Switch off the amplifier and all sources before making connections to your sound system. When you switch on the
system or change sources, set the volume control to minimum and turn up the level gradually.
The position of your Volume Control is NOT a reliable guide as to the maximum capabilities of your sound system. Playing
the system with extreme settings of volume and tone controls may damage the amplifier and loudspeakers.
Do not connect loudspeaker terminals to the mains supply.
Ensure that your loudspeakers are correctly wired and are in phase.
Do not subject your loudspeakers to excessive cold, heat or sunlight.

Preliminaries

Looking After Your Loudspeaker
Your Loudspeakers use a specially sealed finish. They should not be waxed or treated with spray polishes which
will smear and dim the finish. Occasionally polish them with a dry or barely moist cloth to remove dust and
finger marks, etc.

Unpacking Your Loudspeakers
Diamond 10 loudspeakers come in many shapes and sizes. If you are unpacking the larger loudspeakers or a
subwoofer, please remember that these units are heavy. We suggest that you have someone to assist you.
Lift the loudspeaker carefully out of the packing. Do NOT try and lift the loudspeaker using the protective bag.

If you play the speakers with the grilles off exercise great care. NEVER operate speakers with the grilles off if there
are children or pets in the house.

Unpack any accessories carefully.

Occasionally, remove the loudspeaker grilles and brush them gently with a soft brush before replacing them.

If there is any sign of damage or if the contents are incomplete, report this to your dealer as soon as possible.

NEVER use a vacuum cleaner to clean loudspeaker grilles.

Retain the packing for future safe transport of the product. If you dispose of the packing, do so with respect to any
recycling provisions in your area.

NEVER stand objects on your loudspeakers. In particular do not stand flowers etc on them - they are not
jardinieres!
Avoid getting any liquid behind the grille. If you accidentally spill liquid on your loudspeakers, take them to your
dealer for attention before using them again.

Attaching the Spikes to Floorstanding Models - 10.3, 10.4,10.5, 10.6 and 10.7

Do not open the speakers; there are no user serviceable parts inside.

Make sure you have plenty of unobstructed working space.

Never touch the drive units either with an object or your hands.

Place a soft cloth on the floor to protect the loudspeaker.
Invert the loudspeaker onto the cloth.

Servicing

Levelling the Loudspeakers
When the speaker is upright: You
will probably find that the speaker
will wobble with one spike not contacting the floor. Adjust this spike
until all four spikes are on the floor.
With the aid of a spirit level move each spike in and out until the loudspeaker is
level and sitting squarely on all four spikes with no rocking.
Now tighten each locknut securely against the collar in the plinth
to secure the spike
Screw in rubber feet are provided for use on wood or stone floors
etc. and should be attached in the same manner as the spikes.

Cables and Connectors

Delay and LFE Settings
The purpose of delay is to enable surround and dialogue information to arrive at the listener’s ears at the same time
as the Front channels, even when the listening seat is in a non-ideal position.
Rear Delay: If the listening position is equidistant from the Front and Rear speakers, a low delay setting should be
set. The closer the listener is to the Rear speakers the higher should be the delay setting used.
Centre Delay: If the Centre speaker is level with (or slightly behind) the Front speakers, set the delay to zero. If the
Centre speaker is forward of the Front speakers, increase the delay.
LFE: In domestic systems the LFE channel typically feeds into the subwoofer. Where no subwoofer is used, the LFE
signal is combined with Front Channel information. When you set the LFE level at your AV processor, use care as the
powerful low frequencies can overload domestic loudspeakers. If you hear popping or thumping noises coming
from the front loudspeakers or subwoofer, immediately turn the AV Processor's volume level down and then back off
the LFE level. This should cure the problem. If it does not, back off the volume level at the subwoofer (if you are using
one) until the problem disappears.
Please read the relevant sections of your AV amplifier manual and familiarise yourself with the various issues. If you
are unsure, consult your dealer for help.

Choosing Loudspeaker Cable
Specialist audio cable usually offers better performance than general purpose ‘bell’ or ‘zip’ wire.
Choose a cable of suitable diameter – cable that is too thin will limit the dynamics of the sound and may impair the
bass response. Audio cable is polarised, with two cores of different colours, or often a raised rib or coloured tracer in
the case of twin cable. Before you purchase your cable, give careful thought to the positioning of your loudspeakers.
This is especially the case if you are bi-wiring your loudspeakers.
Cable lengths to loudspeaker pairs should be the same for left and right channels in order to equalise the signal
transmission. Allow some slack in your speaker cables so you can alter their position to best advantage.

Preparing Loudspeaker Cable

10mm

Split the twin cores to a depth of about 40mm. Carefully strip the insulation from each
end, leaving about 10mm of bare wire. If the cable is stranded, lightly twist to gather
any loose strands.

40mm

Connecting Screw Terminals
All the loudspeakers use screw terminals.

Troubleshooting

Unscrew the terminal. Insert the bare end of the cable into the hole in the base of the
terminal. Tighten securely.

If your system is not working properly please work through this checklist before returning a unit to your dealer.
Before investigating a problem, always switch off the system at the mains.

No Sound:
The system is not switched on. Speaker cables are shorting terminals out. The wrong source is selected.

The sound lacks bass content: Bass reproduction indistinct:
The front loudspeakers are out of phase. The subwoofer is not switched on.
The subwoofer phase is incorrectly set. The subwoofer crossover control is set too low.

Excessive bass distortion at low volumes:
The subwoofer level is set too high. The LFE level is set too high. The subwoofer is incorrectly wired.

Excessive or distorted bass at high levels:
The system level is set too high. The bass control is set too high. The speakers are too close to room corners.

Distorted or rattling sounds at high levels:
System level too high. Objects on speakers/subwoofer. Objects too close to subwoofer.

Popping or thumping from the subwoofer:
The system level is set too high. The subwoofer level is set too high. The LFE level is set too high.

Indistinct sound: Poor localisation of effects. Poor localisation of dialogue.
One or more loudspeakers is out of phase. (Read the manual for correct connection procedure).

Television picture colour is distorted: (Conventional CRT screens only)

When connecting terminals make sure you leave no strands of bare wire that can
short across to adjacent terminals.
As an alternative to bare wire you can use specialist spade connectors. Your
Wharfedale dealer will be pleased to advise you.

Crossover Networks
Bi-Wireable Networks

Most speakers in the Diamond 10 series use a special bi-wireable crossover panel
with four terminal binding posts. Please follow the drawing carefully to see the
correct orientation of the loudspeaker terminals. The upper terminals connect to
the treble unit, the lower pair to the bass unit. As supplied, the treble terminal pair
is connected to the bass terminal pair via removable metal straps. These should be
left in place for standard installations.

Why Bi-Wire?
Using separate cables for treble and bass units in a Bi-Wiring configuration reduces intermodulation effects and
improves headroom and clarity. To bi-wire, you will need to install two lengths of twin core cable between the
amplifier and each loudspeaker.

The subwoofer is too close to the TV. (Switch off the system and TV. Move the units apart. Switch on after 15 min.).

Standard Networks

D10.SR

The D10.0 compact monitor, the D10.CC compact
Centre Channel speaker and the D10.SR use similar
circular section two terminal crossover panels.
The D10.DFS uses a crossover network panel built
into the speaker’s rear wall. This is illustrated on
Page 7.
None of the above loudspeakers are bi-wireable.

Positioning the Front Loudspeakers

Setting Up a Home Theatre System

The 10.3, 10.4,10.5, 10.6 and 10.7 models are designed to be floor standing. We suggest that they are positioned at least 200
mm from the rear walls and 700 mm from the side walls, facing slightly inwards. The 10.1, and 10.2 models should be stand
or wall mounted though they may be placed on a rigid shelf. The 10.0 model can be stand or wall mounted. The bass
extension will improve if the small speakers are operated closer to the rear wall.

Some of this chapter may appear to repeat the content of the Subwoofer pages - the context however is different.

If the loudspeakers are placed too close to the walls the bass will increase but may be boomy and indistinct. If the
loudspeakers are placed away from the walls, the inward angle may be increased by up to 40%, although this may
restrict the width of the optimum listening position.
A useful rule of thumb is that the listener should be as far from the loudspeakers as they are from each other. The
speakers should ideally be positioned so that the treble units are roughly at ear level to a seated listener. As personal
taste plays a large role, experiment with different configurations and play a wide range of programmes before
finalising the position of your speakers.

2 - 4 metres

Front And Effects Channels: The front loudspeakers are placed on either side of the television screen, 2 to 3 metres
apart. The speakers should be angled slightly so they are aimed towards the listeners.
We recommend placing the rear effects speakers in a high position, behind the listener’s head. If the rear or side
walls are a long way from the listening seat, consider stand mounting the loudspeakers. If the centre loudspeaker is
very high or low, angle it towards the listener's ear level. The front faces of the centre and surround loudspeakers
should also be in line as far as possible.
Subwoofer: As the ear is unable to detect the direction from which deep bass originates, you have freedom to
position the unit. Varying the distance from the wall alters the bass. Placing the subwoofer across a corner boosts
the bass but may impair clarity. The performance of Home Theatre systems is enhanced by using two subwoofers.

Dolby Labs, DTS and THX offer 6.1 and 7.1 formats. Although the precise configuration of these systems will depend
on the capabilities of your processor and you should be guided by those instructions, we would make some
observations.
For 6.1 and 7.1 formats the listening seat should not be too close to the rear wall.
Optimising the time delay so that information from all speakers arrives at the listening seat coherently is critical if
the benefits of these systems are to be fully realised.

Positioning the Centre Loudspeaker
The Centre channel loudspeaker should be positioned centrally between the loudspeakers, close to the television
and mounted above or below the screen.
The loudspeaker should be located on a stable flat surface to avoid
any cabinet movement at high sound levels. If you mount the unit
above the television, move it forward so that the front grille sits
slightly in front of the screen. This will reduce sound reflections
from the screen and the top of the cabinet.
Centre channel speakers are supplied with a set of four self
adhesive mounting feet and two extra feet. Remove the protective
backing from four feet. Place the feet at the bottom of the cabinet.
Attach each foot 10 mm in from the sides of the cabinet and place
them so that the cabinet is supported in a horizontal position with
the curve of the cabinet clear of the shelf. The extra feet enable
you to tilt the cabinet up or down so that the speaker points
directly at the listening position. This facility is particularly useful if
the speaker is mounted under the screen.
A custom stand is available for the D10 CM which allows the
loudspeaker to be positioned under a wall mounted monitor and
has an adjustable vertical tilt for optimal dispersion.

Setting Loudspeaker Sizes and Levels
If you are not using a subwoofer: Set the Front Speakers to ‘Large’. Set the ‘Subwoofer’ option on the processor to
'Off' or ‘No'. The Front channels will now receive all the system bass.
If you are using a subwoofer: When set to ‘Small’ all the system bass will go into the subwoofer. If you choose
‘Large’ the Front channel bass will be reproduced from the Front speakers. Follow the instructions on the previous
page for suitable size and crossover settings.
Once the loudspeaker settings have been finalised, put the AV amplifier into its “Test” mode and adjust the level of
each channel until all channels are reproduced at equal loudness. You may need to adjust the subwoofer output
level. Avoid setting too high a level or you will swamp the sound with bass which be tiring to listen to and may limit
the subwoofer’s ability to respond to large bass transients. Set a sensible level going into the subwoofer. The
subwoofer volume control should be between 12 o’clock and 3 o’clock
15

Fine Tuning Procedures

Positioning Surround Loudspeakers

Set up the subwoofer with all tone controls and filters on your amplifier or processor set ‘flat’.

D10 DFS Surround Loudspeakers

Listening rooms are not ideal. Because of room geometry and construction there will be areas with severe peaks at
some frequencies and severe troughs at others. If you site loudspeakers in such areas the response will be highly
non-flat. It is easier to treat high frequency irregularities by the use of drapes, soft furnishings etc., but very hard to
do the same at bass frequencies due to the very long wavelengths.
To help locate standing waves in your listening room, one idea is to sit in the listening seat and recruit a friend with a
deep voice to speak as he moves around the area where you propose to site your subwoofer - you will soon find out
where not to site it! Where the voice sounds most natural is a good place to start.
Although the subwoofer's bass output is enhanced by walls or corners, so often is coloration. The floor will influence
the sound. The surface under the subwoofer should be stable and unobstructed. If the carpet is very thick, consider
placing the subwoofer on a solid surface such as a marble slab. If you place the subwoofer where it amplifies the
irregularities of the room or the main speakers the result will be bloated, coloured bass. If acoustic guitar and male
voice sounds coloured when the subwoofer is operating at normal level and less coloured if the subwoofer volume
is reduced, you need to address the positioning first before adjusting any controls.
Loudspeaker Phasing: Make sure that all loudspeakers are connected in phase. If there is a doubt about the way
the loudspeakers are connected, check their phasing by playing a mono source - the sound should appear from a
point midway between the front loudspeakers. If this position is indefinite, reverse the connections to one speaker.
Correctly connected loudspeakers give a definite centre sound source with fuller bodied tenor and bass registers.

220 mm

The speakers should ideally be sited 600 mm-1.5 metres above the listening position and 2.5-3.5
metres apart, central to the listener and behind the listening position, preferably on a rear wall. If
the listening position is some distance from a rear wall, the speakers may be mounted on opposite
side walls but always behind the listening position.
Ensure that the wall is sound and can support the product. Drill two 5mm holes in the wall 220mm
apart. Fix a suitable No 8 round head screw firmly into each hole using appropriate wall plugs.
Leave a stub of 5mm protruding from the wall.
Connect the loudspeakers. Align the holes in the mounting brackets over the screw and carefully
lower the unit onto the screws. The speaker should now be securely attached with the spacers
resting against the wall. Now connect the speakers to the amplifier.

Note: As an alternative, the D10 DFS can be shelf or stand mounted. The badge on the D10 DFS
can be rotated to match the orientation of the loudspeaker.

Setting the Phase of the Subwoofer: Phase at very low frequencies is not straightforward to detect. Initially we
suggest you temporarily set the low pass filter to highest setting and the phase to 0º and play some bass heavy music in Stereo
through the main speakers and the subwoofer. From the listening position, switch the phase between 0º and 180º. The
setting which appears to give the greater bass output is correct. Now follow the instructions below for setting the
Crossover filter.
Setting Loudspeaker Sizes: Most digital AV Processors ask you to specify the size of speakers in the various
channels. These are usually ‘Large’ or ‘Small’. This sets the bass management for the system.
Front Loudspeakers: The larger loor standing loudspeakers (10.4,10.5, 10.6 and 10.7) can be set to 'Large'. Smaller
loudspeakers (including stand mounted units) should be set to 'Small' The 10.3 should be set to small. If the bass is
excessive, then set the loudspeaker to ‘Large’.
Centre and Surround channels: The D10. CM centre channel speaker should be set to ‘LARGE’. The other centre
channel speakers and the surround channel speakers should be set to ‘SMALL’ so that bass from these channels will
be directed to the subwoofer. Set the ‘Subwoofer’ option on the processor to 'On’ or 'Yes'.
Crossover Control: If you are using a digital AV processor the initial subwoofer setting should be 85Hz as the
processor will have its own bass management system. After experimenting with various sources you may need to
adjust the Subwoofer Crossover settings. Try to ensure the subwoofer blends into the sound stage - the more
invisible the subwoofer component of the sound field is, the better.
Setting levels: Once the loudspeaker settings have been finalised, put the AV amplifier into its “Test” mode (see
instructions supplied with your processor.) Adjust the levels until all channels are reproduced at equal loudness.
When adjusting the subwoofer output level avoid setting too high a level or you will swamp the sound with bass
which be tiring to listen to and may limit the subwoofer’s ability to respond to large bass transients. Set a sensible
level going intothe subwoofer from the processor.

BI-WIRED CONNECTION

Bi-Wiring
Using separate cables for treble and bass units in a Bi-Wiring
configuration reduces intermodulation effects and improves
headroom and clarity. To bi-wire, you will need to install two
equal lengths of twin core cable between the amplifier and
each loudspeaker.

When the system is not in use for extended periods, we suggest you switch off the subwoofer to protect it from
switching noises caused by domestic appliances, etc. The best practice is to switch the complete system on and off
from a central point. Bear in mind that if you play the system with the subwoofer switched off you will get no bass!
Autopower Switch. (Diamond 10. SX-SUB, 10.MX-SUB). If the subwoofer is left permanently on this may result in
low level hum or noise from the subwoofer when the rest of the system is switched off. Setting the AUTO switch to
ON will automatically turn the subwoofer on when a signal is detected at any of the inputs and turn it off (Standby
Mode) after a period of inactivity. We recommend that the AUTO switch be set to ON for normal operation.

Crossover Adjustment. This adjusts the blend between the subwoofer and the main speakers. and enables the
system to be set up for optimum bass performance. The higher settings are for use with small bookshelf
loudspeakers, the lower settings for large floorstanding models. If you choose too low a setting with small speakers,
there will be a ‘hole’ in the bass response; too high a setting with large speakers will result in the upper bass
becoming bloated. See the next section for further details.
Again the subwoofer should be an extension of the main loudspeakers.

Bi-Ampifying (Bi-Amping)

Phase Switch: If the bass is indistinct or lacks depth, the Phase switch may need adjustment. Set the switch to 0º
and listen carefully to some music with extended bass. If there is insufficient bass output from the sub-woofer set the
Phase switch to 180º. Select the position which produces the most natural, extended bass.

HF+

Volume Setting: Play a programme with extended bass and set the system volume to a reasonable level. Adjust the
subwoofer volume control to produce the desired level of bass. The bass should be even and an extension of the
main loudspeakers. Do not set the control too high or you will swamp the sound with too much bass and clarity and
definition will suffer.

In AUTO mode, when the subwoofer is switched on, the subwoofer will become active. If there is no audio input
present the subwoofer will go immediately into Standby. As soon as an audio input is detected the subwoofer will
then switch on.

When the system is not in use for extended periods, we suggest you switch off the subwoofer to protect it from
switching noises caused by domestic appliances, etc.

Always turn the main volume control to minimum when you switch the system on or off.

Introduction

DIAMOND 10. GX-SUB REAR PANEL

Wharfedale subwoofers are intended for use with high quality domestic sound systems. They are equally effective in
Stereo and Home Cinema applications. Your subwoofer will probably be used in conjunction with Wharfedale
loudspeakers though they will partner any audiophile or top-quality home cinema amplification and loudspeakers.

Unpacking your Subwoofer
Open the carton and remove all the top packing pieces. Lift the subwoofer out taking care not to damage the
cabinet. When lifting the unit from the carton support it from the bottom. DO NOT attempt to lift the subwoofer out
of the carton using the protective bag. The unit is heavy; if you cannot manage it easily, get someone to assist you.

Preparing the Subwoofer
Diamond 10. SX-SUB and 10. MX-SUB: No further preparation is necessary.
Diamond 10. GX-SUB: You should attach the spikes or protective rubber feet to the subwoofer.

With the aid of a spirit level, screw each foot in and out until the subwoofer is
level (side to side and front to back) and firmly supported on all four feet. Tighten
the washer with a wrench to lock the assembly in position.
Note: When using spiked feet take care not to drag the subwoofer and be careful
not to pierce objects or cables which may be hidden under carpets, etc. Spikes
are not suitable for use with stone floors and can cause damage to wood floors,
so consider carefully before deciding which feet to use.

Positioning the Subwoofer
Although the unit may be placed almost anywhere in the room, we recommend that it be placed in front of the
listener and as central to the listening position as possible. There should be a mains outlet within easy reach. The
subwoofer should not be operated within 450mm of a television set as the drive unit magnet may distort the picture.
The bass unit is mounted underneath the subwoofer and moves a lot of air at high volume, so make sure the floor is
sound. Do not place the subwoofer with the bass port near surfaces or objects that may rattle.
We suggest you initially position the subwoofer about 20cm (8 inches) from the wall. Placing the unit close to the
wall will enhance the bass; placing it across the corner of the room will increase the bass further, possibly at the
expense of clarity.
Experiment with locations and sources before making a final decision.

Switch off your amplifier and all connected source units at the mains. Unplug the power cords if necessary.
Make sure the subwoofer is disconnected from the mains and that the ON/OFF switch is OFF.
Before re-connecting your system to the AC power supply, check that all the connections are properly made.
Signal cables should be properly terminated and fully screened to minimise hum. If you connect your subwoofer
via the low level signal inputs, the cable between your control unit or processor and the subwoofer could be
quite long so screening is particularly important. Consult your dealer if in doubt.

All three subwoofers feature the same connectivity.
The 10. MX-Sub has one additional feature - a USB power supply 1! for charging the internal battery of an
optional wireless receiver. This receiver enables a Subwoofer to receive signals from a suitably equipped AV
amplifier or processor without the need for a signal input interconnect. Consult your Wharfedale dealer for details.
