Peavey Hisys H15 Sub

Designed for high-end installations or touring professional audio where compact high-powered point source speakers are required, HIsys powered speakers are suitable for anything from a small bar gig to a dedicated live music venue.
Designed to be as light weight and versatile as possible, creating an easy-to-manage high performance system. The H15 SUB and H18 SUB provide impressive low-end power, considering their compact size. Equipped with analog processing and a stereo input (providing a total of two inputs and two outputs), no external processing is required when matching a sub to a satellite.
Additionally, the HIsys subs have selectable crossover frequency (80Hz, 125Hz), polarity (0, 180¬°) ground lift and adjustable level.
HIsys satellites are not only the smallest in their category (with comparable features), but also full of customized details. What is more impressive is how loud these are for their size; the H15 satellite can reach 133dB and the H18 sub will peak at 135dB.
HIsys speakers benefit from Class D amplification and a large aluminum plate, which strengthens the rear of each respective cabinet. The aluminum plate serves as a heat sink for the amplifier.
