Peavey Electronics","The QW™ 118 incorporates one of the new extra-high power Low Rider™ 18\" woofers and a new compact cabinet design. The QW 118 is a direct radiator subwoofer designed specifically for the high-end pro audio user. The new Low Rider 18\" driver is a milestone in high-power subwoofer design. An incredible 1,600 Watt program rating and extra-long cone excursion come together to produce amazing new levels of clean, deep bass. This makes the QW 118 a superior choice for the bottom end of any high powered sound system. The QW 118 is unusually compact for its power handling, SPL output, distortion performance and bass extension. This is made possible by special characteristics designed into the Low Rider woofer. The QW 118 is well braced and very stiff, as internal pressures produced by the Low Rider woofer can be very high. The vent design integrated into the enclosure includes a vertical brace to further increase enclosure stiffness. The QW 118 vent's large area and long path length allow for a large volume of air to move with very low resistance. This is important due to the massive air flow volumes that the Low Rider woofer can produce.
Peavey Electronics","Despite its compact dimensions for a dual 15 inch bass enclosure, the QW® 215 system can provide over 130 dB of serious low end and take 2,400 watts of power, resulting in large area coverage with excellent punch and high reliability. This subwoofer system utilizes two Pro Rider® 15 inch high power woofers with Kevlar® impregnated cones, 4 inch voice coils & extra-long cone excursion and provide extreme low frequency response down to 34 Hz. Inputs utilize 2 Neutrik® 4-pin input connectors in parallel for full-range, in addition to an 8-pin and a parallel 4-pin Neutrik® connector for bi-amping and daisy-chaining. This subwoofer is ideal for high power and high quality sound systems where space may be an issue. Trapezoidal enclosure design for speaker arraying.
