NEVER CHOOSE AGAIN.

The Speedwoofer is designed for you to experience bass as it happens in real life. It shouldn't matter whether bass occurs in a movie or music, it should sound right. Whether its a drum solo or an explosion, you'll hear and feel every nuance.

The Speedwoofer's excellent transient performance allows it to integrate well with a variety of speaker systems. Whether its a small bookshelf or a large planar floor-standing speaker, the Speedwoofer will complement and integrate seamlessly.

LEGACY AMPLIFIED

RSL's new XDR™ (eXtended Dynamic Range) series amplifier provides class-leading power and dynamics. 400 watts RMS / 1020 watts peak.

DUAL MODE DSP - LFE MODE SELECT

The new XDR™ amp features selectable dual mode DSP. Select LFE mode for deeper extension with greater low-bass output. Music mode offers identical performance to the original 10S with more power and improved dynamics.

INTELLIGENT POWER

High efficient low distortion class D circuitry coupled with oversized half-bridge SMPS. Advanced thermal management and protection schemes for over/under voltage and DC conditions.

PERFORMANCE IS IN THE DETAILS

Precision craftsmanship not found in competing models at nearly twice the price. Proprietary die-cast aluminum frame. Dual-stacked high-grade magnets. Fatigue-resistant suspension with matched high-excursion linear motor. Our woofers raise the bar.

STRENGTH FROM WITHIN

The Speedwoofer's rock solid enclosure features a 1” thick laminated MDF front baffle coupled with cross-braced 3/4” panels via RSL's patented Compression Guide™ technology. Additional corner bracing ensures maximum strength while minimizing resonance.

NEW REAR-VENTED COMPRESSION GUIDE™ TUNING

RSL's Compression Guide™ tuning has long offered improved bass output and transient performance. The MKII's new rear-vented Compression Guide™ tuning reduces air-flow turbulence and perceived port noise. The wide slot port distributes air-flow to allow placement in close proximity to walls (within only 4-5 inches).
