Phase Technology HV81 Down-Firing 8" Audio Subwoofer Sub Woofer Bass Speaker

Phase Technology HV81 - 8" Down-Firing Powered Subwoofer - NEW in Sealed Box
Brand new, factory sealed.
The Phase Technology (PhaseTech) HV81 is a compact down-firing powered subwoofer built to add deep, controlled low end to a music or home theater system without taking up much floor space. It fires straight down into the floor, so it can tuck under or beside furniture and still load the room evenly.
FEATURES- 8" long-throw down-firing woofer with oversized surround for extra-long excursion- Integrated 100-watt servo-controlled amplifier (200 watts peak)- Servo control constantly monitors and adjusts the woofer's output for tight, undistorted bass- Signal-sensing auto on/off - powers up when it sees a signal, sleeps when idle- Variable low-pass crossover to blend with your main speakers- Adjustable gain/level control and phase switch- Both line-level (LFE) and speaker-level inputs for flexible hookup to almost any receiver or amp- Rear slot-loaded port- Frequency response down to 35 Hz- Cube cabinet, roughly 10.75" W x 14.125" H x 14.75" D- Black ash finish
Servo control is like cruise control for the woofer - a sensor watches what the cone is actually doing and the amp corrects it on the fly, the same way cruise control feathers the gas to hold your speed on a hill. The result is bass that stays tight instead of getting loose and boomy when it's pushed.
