I have owned Cornwall IVs and LaScala IIs. It is true that you need a big(er) sub to keep up with the 15” drivers. Although I ended up going with HSU, the owner of Rhythmik steered me away from a pair of 12” subs. I bought a pair of ULS 15 II subs that paired well with both horn speakers.
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.
