The Speedwoofer 10E is brand new so I have no experience with it. But, I started out with a RSL Speedwoofer 10S Mk II and replaced it with the SVS SB2000 Pro. The RSL 10S MkII was good, but being a rear-vented design, it was boomy at certain frequencies. The SVS I have now is a sealed unit, and ii eliminated the boominess I had experienced with the RSL.?
