IN STOCK READY FOR DISPATCH! Enclosed Subwoofer System with Single 10W0v3-4 Subwoofer, Dark Gray Carpet (300 W, 4 O) – Ported Enclosure. This powerful slot-ported BassWedgeT subwoofer system delivers awesome output at an unsurpassed value. The slot-port runs along the bottom of the enclosure and fires on the same plane as the woofer to produce excellent extension and response smoothness. The port mouth is flared to minimize air-flow noises. The ultra-versatile BassWedgeT shape has extended sides so that it can be placed with the woofer firing out or straight down, off the floor of the vehicle. The shape works equally well in forward or rear-firing installations. This gives you plenty of options for tweaking the loading of the enclosure into your vehicle. Finish: Dark gray, high-grade automotive carpet with “JL AUDIO” embroidery on the top edge and Slot-Ported BassWedgeT embroidered on the port mouth. Recommended amplifier power: 75 – 300W. Nominal Impedance: 4 O.
