OSD Audio SMP300 300W Mono-Channel Class D Subwoofer Amplifier

FEATURES:

Variable Low Pass Filter: A front-panel variable low pass filter allows you to adjust the upper frequency limit of the subwoofer to control the overlap of the subwoofer's upper frequencies and the main speakers' lower frequencies. This results in bass that complements the sound from the main speakers rather than overpowers.

Variable Phase Control: The SMP300 also includes a front-panel variable phase control knob that operates over a range from 0 degrees to 180 degrees and allows you to match the arrival times of the sound waves from the subwoofer and the main speakers. This fine-tuning results in bass that is less muddy or thumpy but rather smooth and detailed.

Class D Amp Technology: The SMP300 uses Class D digital amplifier technology that combines the best qualities of both Class A and B amp protocols into a highly efficient compact chassis that is ideal for budget-minded users who want a feature-rich digital sub amp that does not run hot or take up a lot of space.

Why Do You Need Subwoofer Amp? A powered subwoofer has its own internal amplifier. A passive subwoofer requires external power, and most in-wall subs are passive. After all, it's not so easy to install a 100-pound powered subwoofer inside a wall. That's where an amp like the SMP300 comes into play. This amp not only adds necessary power but routes LFE away from your surround speakers, which in turn gives you much cleaner highs and midrange. This subwoofer amp does much more than supply power. It also improves the overall sound quality of your entire surround sound system.
