Definitive Technology Prosub 800 Black

“The Def Tech ProSub 800 subwoofer is a compact powerhouse…the bass delved deeper than I would have thought possible, and the pitch definition was excellent.”
                         — Home Theater

The Definitive Technology ProSub 800 Powered Subwoofer is the perfect companion for home theater/music/ systems in modestly sized rooms.

• Active 8-inch high excursion woofer pressure-coupled to 8-inch bottom-mounted low bass radiator for massive bass with superior speed, control and detail
• Built-in 300-watt amplifier
• Front-side-mounted volume control for fast and easy adjustments
• Compact size makes it easy to fit in any room

Deep, accurate bass adds a visceral impact to your enjoyment of both movies and music. Fortunately, Definitive has bass down pat. The ProSub 800 features a 300-watt amplifier driving a high excursion 8-inch front-mounted direct-radiating woofer that is pressure-coupled to an 8-inch Low Bass radiator on the bottom of the enclosure. The net radiating area of the ProSub 800 is 27% greater than a single 10-inch woofer but with better speed, pitch definition and control.

Definitive's patented Infinite Power Source MOSFET power amplifiers
All ProSub powered subwoofers incorporate Definitive's unique, patented digitally-coupled Infinite Power Source amplifiers with high-current direct-coupled power supplies and discrete MOSFET output devices to ensure perfect high-definition resolution and reproduction of the most dynamic program material. Only the highest quality components are used, including mil-spec glass epoxy circuit boards and precision resistors and capacitors for many years of superior performance. Tremendous current reserves, high peak-power capabilities and two protection circuits ensure that these subwoofers can never be overdriven. There is also a convenient, signal-sensing, auto on/off feature.

Superior detail and lightning-fast transient response
The powerful, high-definition drivers used in all Definitive powered subwoofers were specifically engineered to deliver rock-solid bass with extremely low distortion. The special ultra-stiff cones are joined to specially formulated surrounds and long-throw voice coils and spiders, while the rigid baskets are engineered to hold the massive magnet structures and large voice coils in absolute alignment. The high temperature voice coils are made of aluminum wound with triple insulated ultra-pure copper wire and baked in epoxy for maximum power handling. The result of all this advanced technology is a sub that can reach down to the lowest frequencies with superior transient response (“tightness”).

Rock-solid cabinets for lower distortion
The cabinet of any speaker plays a large part in its performance, as resonance and vibration can add unwanted distortion and potentially drain away important energy from the system. Definitive's subwoofers utilize monocoque cabinets, which have been specifically engineered to be totally inert and vibration-free to ensure absolutely pure sonic reproduction. Monocoque means that the cabinet is of a unitized construction where all panels are permanently joined together into one solid structure. The cabinet walls themselves are high-density medite fused together by space-age polymer adhesives. The front and rear panels are nearly 2-inches thick and the cabinets each incorporate multiple internal braces to ensure total solidity.

Adjustable crossovers assure a perfect match to your system and room
All Definitive's powered subwoofers have continuously adjustable low pass filter controls which allow you to choose a roll-off of from 40 to 150 Hz for the high end of the subwoofer. This unique "dual stage" roll-off is extremely steep, which ensures perfect blending with your main speakers as well as eliminating unwanted midrange from the subwoofer. The benefit of this approach is that it gives you much greater flexibility in placing your subwoofer in your room without being able to hear where it is located.

All Definitive's powered subwoofers also have a separate low-level direct LFE input for Dolby Digital which bypasses the crossover network. The ProSub 800 has a built-in speaker level high-pass crossover preset at 80Hz, and a precision level control allows you to perfectly adjust the volume of the subwoofer to match your system and room as well as your own personal preference.

Easy hookup
The ProSub 800 has a complete range of inputs, outputs and features to allow easy and effective hookup to any system. Both speaker-level and low-level inputs are provided as well as a separate direct-in LFE low-level input (which bypasses the crossover network), which may be used by itself or in combination with left and right channel high- or low-level inputs for the ultimate in subwoofer flexibility and performance.

More rave reviews for the Definitive ProSub 800
“The ProSub 800 reaches down lower than most subs in this class can go.”
                         — Playback

“This little sub [ProSub 800] produced ample, reasonably even output considerably lower than many inexpensive 8-inchers… And it played unexpectedly loudly and cleanly…I had to push it to ludicrous settings well beyond THX-reference from the overall system to elicit gross rattles or thumps.”
