PROFE S S IONA l DX1012-8A FEATURES - THE ALTEC LANSING DIFFERENCE • Point-source single magnet structure Duplex® design • Large Format HF Driver (1.4" exit, 2.8" diaphragm) • 90˚ conical high frequency horn • 12"/300 mm direct radiator low frequency speaker • Passive crossover network with Neutrik Speak-On® and barrier strip connectors • 13-Ply Paintable Poplar Enclosure offered in Charcoal Gray or White with contrasting cloth-covered metal grille • Eyebolt Hanging Hardware included • Neutral grille cloth included that can be dyed to match any décor GENERAL PRODUCT DESCRIPTION Houses of Worship and Auditoriums require speaker systems that can accurately reproduce the human voice and not miss a beat when the task is live or recorded high fidelity music. Standard two-way speaker systems are adequate, but suffer from cancellations and interference from adjacent HF and LF sources. Altec Lansing’s solution is a Duplex® single magnet, point-source component that minimizes these cancellations without sacrificing speech intelligibility or high fidelity, full-range music reproduction. The DX1012-8A uses a unique Duplex® ENGINE component featuring a large format high frequency driver and a 12"/300 mm low frequency speaker & voice coil mounted to the front of the same magnet structure. This point-source design means that all of the acoustic energy is generated in a 1.5" space. The high frequency driver is mated to a 90˚ conical high frequency horn, insuring smooth coverage across the rated bandwidth. A 13-ply poplar paintable cabinet has internal reinforced L-brackets presenting multiple suspension options (horizontal and vertical orientation). Three forged eyebolts are included with each speaker. The model DX1012-8A-G is a charcoal gray painted cabinet with contrasting light gray cloth covered metal grille. The DX1012-8A-W is a white cabinet with contrasting beige cloth covered metal grille. Should you need to paint the cabinet to match the décor of the facility, a piece of neutral grille cloth is included with each speaker. This grille cloth can be dyed to match the speaker cabinet color, or to integrate the frontal area of the cabinet into the architectural space. Where extended low frequency performance is required in Auditorium and House of Worship systems, the Altec Lansing Professional model LF115-8A single 15" flyable subwoofer provides an excellent complement to the DX1012-8A.

The level is then corrected to be equivalent to a 2.83 V 1 m measurement. A near field measurement of the loudspeaker system is performed for frequencies below 500 Hz. This data is then combined with the full range measurement to give an accurate composite frequency response curve. 2 The limits of the frequency response are referenced to -3 dB of the systems rated sensitivity. 3 The sensitivity of the loudspeaker system is the log based average SPL taken over the intended bandwidth of operation for the system with a 2.83 V swept sine stimulus. The data is measured and level corrected in a manner consistent with note 1. 4 The power handling capacity of the loudspeaker system is tested using a full range form of AES Standard 2-1984. The test stimulus is band limited (40 Hz – 16 kHz) pink noise with a 6 dB crest factor. The applied RMS voltage is determined using the minimum impedance of the system. The amplifier used to drive the system has a minimum operating headroom of 6 dB referenced to the RMS voltage. 5 The maximum output level of the loudspeaker system is calculated based on the sensitivity and the power handling capabilities of the system. 6 The coverage angles for the loudspeaker system are taken as the -6 dB points of the directivity response and averaged from 500 Hz – 16 kHz. 7 The minimum impedance of the loudspeaker system is taken over its intended band of operation. 8 The distortion measurements of the loudspeaker system are performed at a distance of 1 m with RMS input voltages corresponding to 1% and 10% of rated system power handling calculated using minimum system impedance. The distortion percentages are log based averages from 300 Hz – 3 kHz. 9 Before attempting to suspend the loudspeaker system, consult a certified structural engineer. This loudspeaker system can fall from improper suspension, resulting in serious injury and property damage. Suspend this loudspeaker system using no less than two of its suspension points. Maximum enclosure rigging angle is 45°. Use only the correct mating hardware, forged shoulder machinery eye bolt, Mil Spec MIL 51937-3. All associated rigging is the responsibility of others.
