Definitive Technology ProSub 1000 Review

Features

Let’s see Definitive Technology ProSub 1000 specs. The compact Definitive Technology ProSub 1000 subwoofer is equipped with a 10-inch woofer that is not mounted on the front panel and an acoustically connected 10-inch passive radiator facing the floor. This solution allowed us to get deep, controlled and unpainted bass, as well as greatly simplify the task of placing a subwoofer in the room. The magnetic system of the woofer is designed to bring from the amplifier to 750 watts of power, which ensures exceptional reliability. The frequency range is 18 - 150 Hz.

Design and build

The speaker diffuser is very light and rigid, which significantly reduces resonances, and is mounted on an elastic suspension of a special shape, which allows it to perform piston movements of large amplitude. The winding of the voice coil is made in such a way as to achieve maximum linearity of the diffuser stroke, and the robust basket has enlarged openings for free passage of air flow from the back of the diffuser. The amplifier in the subwoofer has output stages on discrete MOSFET transistors, made using the patented Infinite Power Source technology, and develops up to 300 watts. The amplifier circuit is mounted on printed circuit boards of "military" quality, using precision resistors and capacitors. The ProSub 1000 uses a dual protection system to prevent damage in the event of any emergency. To eliminate the danger of coloring the sound at high listening volumes, the subwoofer housing has an almost monolithic design, with a very tight connection of the panels.

Connectivity

The subwoofer has an LFE input, as well as high-level inputs for connecting to the acoustic outputs of an amplifier or receiver. There are also filtered acoustic outputs for connecting satellite speakers. The two-stage input filter allows you to adjust the sound of the subwoofer for precise matching with any main acoustics.
