Yamaha HS8S 8" Powered Subwoofer 150W Amplified Sub

The HS8S 8" Powered Subwoofer from Yamaha features an eight-inch cone woofer that is capable of up to 150W of output. It can reproduce frequencies down to 22Hz and features variable low and high cut filters between 80 and 120Hz. You can connect to the HS8S through its stereo XLR or 1/4" TRS inputs. It also has stereo XLR extension sub outputs.Low Resonance Enclosure DesignHS 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 soundNoise Reduction TechnologySpeaker 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 6dBControls and ConnectivityThe 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 outSystem Type Powered SubwooferFrequency Response 22 to 150 HzTransducer 1x 8" (203 mm) ConeOutput Power 150WInput Sensitivity -10 dBuImpedance Input: 10 kOutput: 600 Inputs 2x Balanced XLR3-31 Type2x Balanced 1/4" (6.35 mm) TRSControls Level controlPhase Switch: Normal/Reverse.High Cut Control: 80 to 120 Hz, center clickLow Cut Control: 80 to 120 Hz, center clickLow Cut Switch: ON/OFFIndicators 1x Power ON, White LEDDimensions (W x H x D) 11.8 x 13.8 x 15.3"
