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).
