SUBA21 Single 21" Powered Subwoofer

Cerwin-Vega SUBWOOFER Series — The Pulse of the Performance Big air displacement, compact footprint. The SUBA21 (Powered) proves that you don't need a massive dual-cabinet to get deep, earth-moving bass. By pairing a single, high-excursion 21" woofer with a dedicated 1800W RMS power module, this active sub delivers a massive 135dB peak SPL in a form factor that’s easy to move and even easier to hide. Why the SUBA21 is Your Next Must-Have: Single 21" Precision Experience the unique "breath" of a 21-inch driver without the bulk. With an 1800W RMS internal amplifier tuned specifically for this driver, the SUBA21 hits down to 40Hz with incredible authority, providing a rich, cinematic low-end extension that smaller drivers simply can’t replicate. Road-Ready & Install-Safe Space-saving doesn't mean fragile. This cabinet is built from multilayer composite plywood and finished with wear-resistant polyurea paint, ensuring it stays looking new through countless load-ins or years of fixed use. It’s a professional-grade build that handles high-vibration output with ease. Ultimate Versatility: Mounted or Mobile The SUBA21 is the ultimate "problem solver." Its 600mm width makes it perfect for tucking under stages or into tight club corners for permanent installs, while the built-in power and XLR connectivity make it a favorite for mobile DJs and rental companies who need a fast, one-man setup. From the Stage to the Streets Whether you’re reinforcing a point-source system in a lounge or adding extra "thump" to a mobile line array, the SUBA21 delivers professional power without the bulk. It’s the perfect balance of size and soul—loud, proud, and built to last.
