Speakers for leading edge, transients, speed and big sound

The JBL K2 S9900's have my vote for what you want. You won't hear much better than these for smooth, powerful and clean reproduction. As for lack of extreme bass, you could move the speakers closer to the corners or add subs. personally I would chose the former.

So, guys, wait a second. The JBL K2s have big honkin 15" woofers mounted in big-arse bass reflex cabinets like it’s 1975, but they’ve got no bass. No bass. And a used pair is asking $18K. Am I reading this right? Can someone please describe what makes these speakers attractive?

Thanks again. What do we feel about the Wilson Alexia 2? for electronics, I have some leftover Crown amps from my JBL M2 system that I may replace

Some speakers with big woofers don’t actually go extremely low because they have low excursion (the cone does not move very far back and forth).  These designs prioritize clean and fast response.  I prefer this kind of bass.

I hear you and I respect your sonic preferences, but how does low xmax translate into clean, and especially fast, bass? Especially when paired with a 15" paper cone?
