Two-way loudspeaker with back coverPrevious page


The BCM8-40TWBC is an two-way built-in loudspeaker that can be used as a 8 ohms or 70/100 volt loudspeaker. In 8 ohms use, you can connect up to 2 loudspeakers in parallel on each channel of a standard 4 ohms amplifier. For 100 volt use, the BCM8-40TWBC is equipped with a high-quality 100 volt transformer with several power tappings. Therefore it can be used in projects with high ceilings or places with background noise where a little more power is needed.

The built-in 8” coaxial plastic speaker driver is designed of wide frequency response 90-20kHz what results in a very great sound. To complete the sound, a 1,5” tweeter has been integrated. It makes the BCM8-40TWBC very suitable for the distribution of microphone calls and background music.

The housing is made of high quality ABS. The woofer is made out of enforced polypropylene, what makes it moisture-proof. The loudspeaker is easy to install, due to its simple, quick mounting system with only 3 screws. These screws are hidden behind the loudspeaker grill, what gives the loudspeaker a modern and striking design.
