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 compliment and integrate seamlessly.



LEGACY AMPLIFIED
DUAL MODE DSP – LFE MODE SELECT
INTELLIGENT POWER
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 transient performance. The MKII’s new rear-vented Compression Guide™ tuning reduces air-flow turbulence and perceived noise. The wide slot port distributes air-flow to allow placement in close proximity to walls (within only 4-5 inches).
WIRELESS READY
The new reduced-size AT-4 wireless transmitter can convert any Speedwoofer 10S MKII to wireless. Enjoy the freedom to discover the best location for your Speedwoofer. Running multiple subs? The AT-4 will pair with up to 4 Speedwoofers at the same time. Still only $50!
