That's quite a statement there. I don't know that I woild agree. Also crossing subs as high as 120 hz? You don't find that boomy/very directional from the subs? I understand what you are saying about speakers rolling off and can see where you are going with that mindset. I would strongly prefer not to use a sub with my 396s, but I found a sub to be a MUST for my needs. Volume matched and crossover over correctly, quality sub(s) can certainly add to the experience in music listening. I found the bass very satisfying from the heresy IIIs. Although I was tempted to add a sub (and I did), I found I preferred them without despite frequency response on paper and I listen to plenty of music with very extended bass. For the music I like that doesn't have said extended bass (and even on some of it) those heresy IIIss are AMAZING speakers and a damn bargain at prices they can be had at.
