## Summary description

The Biamp Commercial Audio CMSUB8 is a 1-way wired loudspeaker designed for conferencing systems. With a power rating of 80 W, it features two drivers, an impedance of 8 Ω, and a frequency range of 50 - 200 Hz. The speaker has a sensitivity of 88 dB, ensuring clear sound reproduction. Its sleek white design makes it suitable for various environments.

## Long description

The CMSUB8 is an 8" dual-coil ceiling subwoofer designed to deliver deep, controlled bass while remaining visually discreet. Its compact, white design and aluminium grille allow installation in ceilings or other concealed locations without occupying wall or floor space, and the construction offers suitability for humid environments. The CMSUB8 pairs well with small to medium satellite speakers such as CM3T, CM4, CM4T and small cabinet speakers like the MASK4(T). It is intended for infinite baffle use (for example mounted into a ceiling); no backbox is required, although when installed into an enclosure (furniture or cabinet) a closed box of at least 20 litres is recommended.
Advantages
The CMSUB8 provides deep bass from a recessed ceiling installation while keeping a low visual profile. Its dual-coil design and 80 W power rating deliver reliable low-frequency reinforcement, and the aluminium grille improves durability in humid conditions. The speaker’s impedance and sensitivity make it compatible with a wide range of wired amplifier systems and it integrates well with APART-Audio CM-series satellite speakers.
Suitable for
Background music systems in commercial or hospitality spaces
Distributed ceiling audio installations requiring discreet low-frequency support
Small- to medium-sized conference rooms paired with CM-series satellites
Environments with occasional humidity where an aluminium grille is beneficial

How to use
Install the CMSUB8 into a ceiling cavity for infinite baffle operation, ensuring the cut-out and mounting follow the manufacturer’s instructions. Connect the speaker to a compatible wired amplifier or audio distribution system, observing the 8 Ω impedance and recommended power handling. For installations inside furniture or a dedicated enclosure, mount the speaker in a closed box of at least 20 litres to preserve low-frequency performance. Position and calibrate the subwoofer together with satellite speakers to achieve a balanced bass response across the listening area.
Usage recommendations
For increased low-frequency output in acoustically challenging rooms, add additional CMSUB8 units and distribute them across the area rather than driving a single unit harder. Use appropriate crossover settings and amplification to match the speaker’s 50–200 Hz range and 80 W rating.
