Speakers for leading edge, transients, speed and big sound

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?

Von Schweikert speakers with a easy placement due to their adjustable active bass.  The more expensive models have more adjustments.  The smaller, less expensive models play big, superior dispersion and adding a pair of 10" shockwave subs should power/balance the sound in moderately large size rooms.  Otherwise, Rockports are balanced sounding with outstanding sonic characteristics.  If you want precision over musicality, there are many modern speakers from Vivid, Magico, Wilson, B&W, Borressen, et.al.  which will fill the bill, the bigger units with bigger, defined and fast bass.
