Product Technical Data Sheet
Model CM208W-TB
Description
The CM208W-TB is a dual 8” subwoofer intended for background music
playback. It is specifically designed for installation in tile grid ceilings.
The input section includes a low pass crossover as well as high passed
outputs that incorporate our series parallel network for driving four 8 ohm
satellite speakers at an 8 ohm total load. Additionally, by removing a pair of
jumpers the subwoofer can be used with DSP based bi-amp designs while
still incorporating the series parallel network for the high pass satellite
outputs to avoid using 70V transformers.
As an option the subwoofer can be ordered with an internal 70V 60W
transformer. This transformer is in circuit before the crossover so the
subwoofer and four CM Series satellites can be powered by one 70V
amplifier channel if desired.
Key Features

1. LF at -10dB
2. Full bandwidth pink noise is applied and amplified to a level and
measured at the loudspeaker terminals - corresponding to 1 Watt as
referenced to the loudspeakers nominal impedance. SPL is measured in
a half-space environment in the loudspeakers far field. Data is
extrapolated to 1 Meters distance from the loudspeaker.
3. AES established with ambient temperature at 22C in accordance with
AES/2-1984 standard. IEC stated in RMS voltage according to IEC 268-5
