I bought a pair around a year ago and just love them. Very detailed, great soundstage, refined etc... As far as deep bass goes, there is none. If you look at Stereophile's measurements, they are flat down to 50hz, down 5db @ 40hz and down 10db @ 30hz.

Around 5 months ago I purchased a REL Carbon Limited sub and liked what it did so much I just bought another one. With the 2 REL's paired with the YG C 2's the sound is unbelievably good. I run the subs in stereo via the 'Speakon' connection system and cross them over @ 45hz and use very little volume. For me in my room I found it works better to have speakers that are not quite full range and use subs to dial in the deep bass. With speakers that play deeper I found it more difficult to get the right mix of deep bass with the rest of the frequency (in my room).
The Carmel 2's are very sensitive to everything upstream....Don't try to use cheap electronics with these speakers. If you have a small room and listen to small scale music you might be ok with no sub but if you like larger scale material a high quality sub would be a must.....Hope this helps.
