Big bass out of a small box. The SQL subwoofers are specifically designed to work in small sealed or small ported boxes and provide deep, clean, loud bass. Subwoofers either sound good but are too dainty to be turned up, or sound “ok” but can get pretty loud. Our SQL subwoofer accomplishes the perfect mix of sounding excellent with music while possessing the capability to keep up with the most demanding closet bass head in all of us. We accomplish this by using a larger and longer voice coil with a tight gap powerful motor. Mass has been balanced precisely to provide bass from down below human hearing up to your subwoofers crossover point. Controlling the moving assembly are two large spiders and a tall rubber surround for linear suspension movement and lower distortion. Lower distortion continues with stellar 28.4 mm one-way linear excursion from the voice coil and motor topology. 28.4 millimeters each direction for distortion-free bass. Solid power handling of 1000 watts RMS and a small sealed enclosure recommendation of 0.80 to 1.0 ft^3. Vented enclosure is 1.6 ft^3 tuned to 33 Hz.
