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.

Thanks to all who offered their thoughts on this. I went with one SVS SB 1000. Easy to tinker with settings through the app. Huge positive change in my system. I can see where 2 would be peachy, but down the road maybe. Don’t think I could go back from this. Kind of magic . Box disappears but music gets bigger.

YES! Exactly!!! This is what a good sub(s) can do. It offers SO MUCH more than just more bass. Add another sub and you’ll be equally amazed at what it can do. Subs add ambiance and have presence we can’t know until we get a good one and properly set up it up. Turn the sub off and the music and soundstage just shrinks. It’s amazing. Those who don’t try will never know the difference. Goodonya!!!

I don't think there's any doubt a well integrated sub is a wonderful addition.  The problem is usually the work needed to integrate a sub well.  For a novice, success can seem random, and often frustrating.
