Definitive Technology ProSub 800 review: Definitive Technology ProSub 800

For example: the built-in 300-watt, high-current amplifier uses costly MOSFET output transistors. The front-mounted 8-inch woofer's bass output is augmented with a bottom-mounted 8-inch passive (infrasonic) radiator. And the sub's volume control is conveniently located on the side panel.

Connectivity includes one rarely seen feature: filtered, high-pass speaker-level outputs that can be used with Definitive Technology's satellite speakers. There are also the speaker-level inputs and the more common LFE input.

The ProSub 800's cabinet walls are constructed from high-density medite panels fused together by polymer adhesives. The front and rear baffles are extra thick, and the cabinet incorporates internal bracing to ensure total solidity. The front cloth grille is no-frills basic, but it is removable.

Movies like House of Flying Daggers were impressively deep and well defined--far superior to what we've come to expect in similarly sized and priced subs. The ProSub 800 was just as accomplished with music. It was able to control the lowest octave of bass and still integrated well with both the Definitive Technology SSA-50 soundbar speaker and the ProCinema 800 satellite speakers we had on hand. At $400, it's a good addition to either of those systems, or any other surround setup that needs to be anchored with ample bass. Alternately, you can spend $100 more and opt for the ProSub 1000--it's essentially the same design, but with a 10-inch woofer (and corresponding infrasonic radiator).
