Owner’s Manual
Congratulations
Congratulations on your purchase of a Definitive Technology ProSub Subwoofer. This revolutionary subwoofer utilizes state-of-the-art components, a non-resonant monocoque cabinet and low diffraction construction in order to achieve the most lifelike sound possible in your listening room for many years to come. The ProSub is a compact, high quality powered speaker system intended primarily for use as a subwoofer in superior quality music or home theater systems.
This ProSub powered subwoofer incorporates a high current power amplifier, electronic crossover and precise equalization in order to achieve the highest possible level of low frequency performance. The amplifier and elec- tronic crossover are completely self-contained modules which are housed in the subwoofer. The ProSubs incorporate Definitive’s proprietary PowerField® technology, by which the amplifier is specifically engineered in conjunction with the driver for optimum load matching and power transfer characteristics. The integrated electronic crossover incorporates high level inputs and outputs as well as a low level input, precise equalization, continuously variable low pass filter (between 40 and 150 Hz), fixed speaker level high pass filter (to match the ProMonitors) and a precision volume control. The tremendous built-in flexibility allows easy, seamless integration with all main speaker systems and optimum performance in any room. The crossover incorporates circuitry which allows for exceptional performance as either a single subwoofer or when two subwoofers are used.
Our engineers have spent many years in developing this product. To ensure that you only experience the finest performance possible from your subwoofer, we encourage you to take a moment with this owner’s manual and familiarize yourself with the proper installation and setup procedures for your subwoofer.
