dayton hpsa1000 rack amp. I forgot about the behringer EuroPower EP2500 before I ordered the dayton but at least I know dayton has a good reputation.
Finally, a freestanding high-power subwoofer amplifier designed for the DIYer, installer, and systems integrator. This unique mono subwoofer amplifier delivers the raw power of a pro-sound amp, but with the features and flexibility of a dedicated subwoofer amplifier. It can be configured for stacking with other audio components, and includes removable ears for mounting in standard audio racks (2RU). The stealthy pop-out knobs on the front panel make adjustments easy, while minimizing the risk of accidental disturbance. The subdued brushed black aluminum faceplate allows this amp to cosmetically blend with any type of audio gear. From a performance standpoint, an adjustable low-pass crossover, adjustable phase, and parametric EQ band allow you to tweak the sound of your sub to match your room. Sophisticated soft clip circuitry provides cleaner transient peaks while protecting your driver from overexcursion. Auto on/off or triggered 12V input allows easy integration into automated systems. Accepts RCA line-level inputs, includes insulated binding posts for the speaker outputs, and accepts a 12V trigger via a 3.5 mm mini-jack.
