HS Series cabinets are designed to eliminate unwanted resonance and increase the

accuracy of sound reproduction to their extreme limit. The enclosures are constructed from

a dense MDF with a damped acoustic response. HS Series engineers also employed a traditional three-way mitered-joint technique. Common to architectural design, this construction firmly anchors the corners of the enclosure to improve durability and eliminate unwanted resonance that can influence overall sound

Speaker port design can greatly influence the clarity of overall sound. Often a vortex at the either end of the port can generate air vibrations inside of the port, causing unwanted noise. By adopting a noise reduction technology that incorporates an analysis of

a visual representation of the sound, Yamaha's engineers are able to control and reduce the vortex. Through this analysis Yamaha has arrived at a port design that reduces noise up to 6dB

The HIGH CUT control sets the cutoff frequency of subwoofer output high-frequency attenuation from 80Hz to 120Hz, while PHASE switch adjusts the phase of the subwoofer output.

The LOW CUT switch and LOW CUT controls enables attenuation of low frequencies for output between 80Hz and 120Hz. The HS8S subwoofer is equipped with XLR and TRS phone jack inputs

and for outputs XLR for L and R and EXT SUB out
