immediately corrected. Use only hardware which is rated for the loading conditions of the installation and any possible short-term

unexpected overloading. Never exceed the rating of the hardware or equipment. Consult a licensed, professional engineer when any

doubt or questions arise regarding a physical equipment installation.

Introduction

Part of the DCS Digital Cinema Speaker Series, QSC’s SB-15121 subwoofer offers the highest performance available for cinema subwoofer applications.

It is designed for use in premiere cinemas and post-production applications where the ultimate in performance is required.

The massive 21 low-frequency transducer features a 6 diameter voice coil in a vented, neodymium magnet structure that is designed to dissipate " "

extreme amounts of heat and allow for excursion that is double that of typical 18 transducers. Ensuring cool operation, even at high power levels, "

increases driver lifespan and decreases power compression at high drive levels.

The large, ported enclosure ensures response to the lowest audible frequency for bass that you can not only hear but also feel. The enclosure is con-

structed of high quality, heavily braced MDF Panels. Large, fully radiused ports ensure smooth airﬂow, especially at higher drive levels. This prevents

potentially audible port turbulence noise. Both internal and external port openings are ﬂared.

With symmetrical port loading, the bass ports are evenly spaced around the transducer, making internal pressure more uniform across the back
