Powered Subwoofer: The CS-8080HD features a 5x10-inch
racetrack style subwoofer powered by the built in 300 watt amplifier. The
active driver is pressure coupled to two 5x10-inch racetrack style passive
radiators for a total bass radiating area larger than a 12-inch round woofer.
The class D amplifier features an integrated Digital Signal Processor (DSP)
that equalizes the woofer system to extend and smooth the bass response. A
Linkwitz-Riley crossover network maintains a smooth output around the crossover
frequency. The upward-firing woofer requires 1" of clearance above the
Midrange: The two midranges used in the CS-8080HD are
5-1/4" second generation BDSS (Balanced Double Surround System) drivers.
The midrange cones are injection molded polymer composite with cast aluminum
baskets. BDSS is Definitive's patented technology that supports the speaker cone
at both the inner and outer edges allowing longer and more linear excursion for
greater clarity and detail. The new Linear Response Waveguide (patent pending)
smoothes off-axis frequency response and disperses sound over a wide area (the
HD in the part number stands for High Dispersion).
Tweeter: The tweeter is a pure aluminum dome, heat-treated
to relax the crystal structure, then coated with a ceramic to produce extended
Voice-Matched: The CS-8080HD is a full-range low-distortion
center channel speaker, timbre-matched to blend perfectly with the Definitive
Technology BP-8080ST SuperTower main speakers.
Binding Posts: The speaker terminals are gold-plated, 5-way
binding posts and will accommodate spade connectors, single or dual banana plugs,
pin connectors, and bare wire up to 10 gauge.
Line Input: In addition to the speaker level inputs (which
are required), if the connected receiver/amplifier has a center channel line
level output, it can also be used to send signal to the powered subwoofer
section of the CS-8080HD (this input should not be used with the receiver's LFE
Bass Level: A rotary knob on the back panel controls the
output level (volume) of the powered subwoofer.
Auto Power: When a signal is delivered to the CS-8080HD the
amplifier automatically turns on and the rear panel LED lights. Once the signal
is removed the amplifier automatically turns off (after about an hour).
