Add a subwoofer?


I run a pair of Cornwall 1’s driven by primaluna, VPI, and Sutherland 20/20.  Room is 34 x14 x 14 high.  I love the Klipsch, but never felt like they were overly heavy bass.  I’m curious about a subs ability to “fill in” the sound.  I called a dealer regarding REL’s smaller products.  I was told that the Cornwall has huge bass and I’d need a very large sub to notice a difference.   Really can’t afford a quality big subwoofer.  ie thousands of dollars.  Not wanting thumping bass, just fuller sound.  No experience with subwoofers so, ,,,,
Thanks for your input.

I second the HSU's. Good value for dollars spent. Take a visit to their website.

The also answer their phone and talk to you.

Great info.  Thanks to everyone.  This will be a journey.  And moving furniture a bit I’m sure. Very cool stuff 

Subs always help unless they aren't set up right.  It sounds like you want to do it right, which means filling in low end information that the speakers can't reproduce.

While the Cornwalls are very efficient, it's not going to be hard to "keep up" with them as some others have said.  I have Klipsch Chorus and Quartets.  I have a Rythmik F15 with the Chorus and the volume level is barely on. 

You could easily get by with a moderately powered 12" sealed sub.  My first recommendation would be Rythmik, but SVS has some very affordable models that would work.  Two subs are better than one, and 12" sealed subs don't take up much space and would be much better than getting a single 15" sub. 

If you want to pressurize the room and feel your bowels shake, you'll need to step things up, but if you just want to fill in the bottom end, you'll be fine with one or two small subs.

@soix You obviously are not familiar with Cornwalls which are capable of prodigious output. They will swamp two 12" drivers. 

I many systems subwoofers do more harm than good. If the OP is a critical listener and continues along the path he is on he will be very disappointed.

@mijostyn First, the OP has already said he’s not satisfied with the bass he’s getting and is looking for improvement, so clearly their bass output is not all that prodigious in his room. Second, there’s no way a pair of 12” subs that go down to 20Hz -3dB will not add meaningful information that the Cornwalls are simply not physically capable of — that the subs’ drivers are not 15” is determinative of nothing.  And third, he can try the SVS subs with absolutely no risk, and I’d bet big $$$ he would not be disappointed and would not return them.  There are precious few speakers (if any) that wouldn’t get at least some benefit from adding two good 12” subs just to better manage in-room bass issues if nothing else, and the Cornwalls are not “magic speakers” that somehow defy physics and logic.
