PDFSP 118 Specifications (pdf)

The SP 118 is a subwoofer designed to enhance the low end in SP and other full-range speaker systems. Other uses include bass guitar, keyboard and drum monitoring.

The enclosure is constructed of Aspen hardwood plywood with internal bracing covered in a heavy-duty, textured Hammertex™ covering. A powder-coated, perforated steel grille covers the front of the enclosure. Recessed steel handles on either side provide portability. A pole guide for support of a pole-mounted, high-pass enclosure is provided on the top face of the SP 118. Rubber feet are provided on one side for horizontal use. Rubber feet and corner casters on the bottom and a corner handle on top make moving the enclosure an easy, one-person operation.

Inputs are at the rear of the enclosure, and consist of two ¼" jacks and one four-pin Neutrik® Speakon® jack. All inputs are in parallel, with the +1 and -1 pins of the Neutrik jack connected to the Pro Rider® driver and other jacks.

This low frequency enclosure is comprised of a single 18" Pro Rider subwoofer driver in a vented alignment. The Pro Rider driver delivers superior performance due to its advanced cooling system, large 4" voice coil with edge-wound aluminum wire and Kevlar® composite cone. This design provides strong bass extension and high power handling to complement a full-range sound system.

As the SP 118 does not include a passive subwoofer crossover, input should be electronically filtered for subwoofer applications. In addition, for high power operation, a high-pass filter set at 35 to 40 Hz and 12 to 24 dB Butterworth should be used to improve performance and reliability.
