Cornwall IV and subwoofers

@wrm57 The Cornwalls are fantastic speakers and I enjoyed them immensely. The LS II just takes everything up a notch, and it's hard to beat a fully horn loaded speaker.

@alan60 I could live with the CW IV without a sub. The bass is very good. The sub just rounded things out a bit on some music. But they can certainly be enjoyed without one.

I run CWIVs with two REL T9i subs.  I would think T7i (smaller units) would suffice.  They are run off speaker level outputs from the amplifier.  They are not necessary, but fill in the lowest octave and provide a good sense of stage depth and make things seem even more lifelike.  

I have Cornscalas, pretty much same specs as CWIV.  I have 100 Hz crossover and feel the subs are "part of the music."  I have two 10" subs.  

@jbhiller Yes, rightly said. I tried the CW4s by themselves and they sound great. I tried them with the REL subs and everything was just better. "More lifelike" is apt. 

I demoed the Cornwall IVs a few weeks ago and the bass floored me and my wife, when turned up. I can’t imagine adding subs to these.
