“When I heard I was going to review a budget $399 subwoofer, I dreaded the month I’d miss my reference subs. I couldn’t have been more wrong!”“I was amazed that such a small sub could produce so much room-shaking bass.”“clean, punchy bass… tight, with no overhang to speak of”“2 Speedwoofers – one hell of a bargain for $800.”“when someone asks me to recommend a budget sub under $500, this will be the first I’ll mention. And a sub under $1000? I’ll recommend two of them.”

“By any measure, this is a fantastic 10-inch sub, one that in many ways delivers the performance of a 12-inch offering”

“a delicious blend of fury and finesse”

“It’s hard not to be impressed by the way the RSL sub doesn’t muddy the song’s rhythm section the way other (even much more expensive) subs do.”

“no audible distortion or chuffing, but plenty of slam-you-in-the-gullet weight.”

“The Speedwoofer 10S… delivers the sort of clean depth and nimble upper-low-bass performance that I never would have dreamt possible from subs of this size (much less this price!)”

DREAMING OF
MOVIE THEATER QUALITY BASS
FOR YOUR HOME THEATER SYSTEM?

Running dual Speedwoofer’s improves distribution and boosts output for an even more awe-inspiring experience.

One Speedwoofer is great. But two Speedwoofers is even better. That’s because two subwoofers have certain advantages over one.

For starters, two subwoofers can provide better bass distribution than one. Room acoustics can cause peaks and valleys in your bass response. In one seat you’re overwhelmed while in another, you may hear almost nothing. With two subs, one will fill in the valleys of another, evening out the distribution. Often, spacing subs apart from each other will achieve this effect (top image).

In addition to improving distribution, dual subs increase output – by a LOT. Two subs placed apart doubles the output with a +3 dB increase at all frequencies. On the other hand, two subs placed together (bottom image) gives you up to a +6 dB increase. That’s FOUR times the output!

With the Speedwoofer 10S’s ridiculously low internet-direct price, you can take advantage of the benefits of two exceptional subwoofers for the same price as one average sub at a big box store. Plus, if you decide to go wireless, you can daisy chain the subs so you only need one transmitter!
