TFM-420 bi-amped floor monitor
The TFM-420 is a high performance professional bi-amped floor monitor consisting of a custom designed 4”
voice coil neodymium 12” low frequency driver, and a high power 1.4” diaphragm neodymium high
frequency compression driver on a custom 40° x 60° waveguide in a compact vented enclosure.
The drive units are mounted side by side on a 37° baffle, producing a small footprint which
results in a highly efficient wedge monitor package, ideal for use wherever high SPL and
exceptional intelligibility is required. A low box profile is maintained, thereby improving
sightlines, by mounting the HF horn alongside, rather than on top of, the low frequency driver.
The HF horn pattern is designed to give very even coverage both close to, and standing back
from, the monitor while at the same time minimising sound spillage into adjacent microphones.
As a result the TFM-420 offers impressive feedback rejection, developing high sound pressure
levels without the need for excessive equalisation. The TFM-420 has been designed as a
symmetrical mirror-image monitor, allowing multiple units to be used with one monitor inverted
to form left and right pairs. The included pole mount socket also allows the TFM-420 to be used
vertically as a front of house loudspeaker.
