SPEEDWOOFER 10S MKII
The Speedwoofer 10S MKII takes the multi-award-winning and revolutionary performance of the original to the next level. A brand new RSL XDR™ series (extended dynamic range) proprietary DSP amplifier design, delivers even more peak and continuous power than ever before – 400 watts RMS with 1020 watts peak. The XDR™ amplifier now offers selectable dual mode DSP for a more optimized movie and music experience. Select movie mode (LFE) to use the MKII’s extra power for deeper bass extension and higher output. Music mode sets the performance to match the original 10S performance but with more power and greater dynamics. A new rear-vented Compression Guide™ tuning achieves the same class leading performance but with reduced air restriction and port noise.
