I must admit that a LARGE PART OF MY BIAS stems from my "long running" complaint regarding the shor-comings of passive systems in closely proximating "dynamic transparency" on the whole!
I still remember the first "real" high-end system I heard many years ago. The guy who's home system it was my pleasure to have heard, had a completely active system, that just blew me away!!!!...I din't hear anything even remotely close to that system, dynamically at least, until many many years later. His system was so dynamic IT HURT!!! There was soooooooo much power and dynamic ability there, that it left everything else I heard rather flat sounding and "gut-less" by comparison over the years.
Granted, that system was also very refined and "high-end" sounding as well...not just strong and dynamic!
That said, ESPECIALLY IN REGARDS TO HOME THEATER, I have very little impatience with whimpy sounding passive speaker sysetms that can't DELIVER THE GOODS when it comes to dynamic transparancy and general power deliver/dynamics!..which I think a good HT system should do.
I think more high end speaker makers should be building, at the very least, active woofers(for the demanding bass) into their speakers!
I have talked with many high end designers, and I find that the arguments they usually offer are "cost factor", "flexibility", "tradition", "practicality"(heat build up, space issues, etc),"public acceptance"! To me, I think the only "move-up" that can be made in transducers is to do more active speaker/woofer designs!
It's this reason, not to mention that that's what the "home theater experts" in the field have found, that I think the only way to really handle bass magangement in a passive sysetem, is to enlist the help of a crossover to a powered woofer of some sort!..it's like effectively bi-amping your system, and adding and active woofer to your bass chores...it's closer to what you need for dynamic accuracy.
If people don't want to do this, no problem. But don't think you're going to blow anyone away with your action adventure demo's at home!...that's all I'm saying. Because a lot of what's "exciting" and "involving" from a movie soundtrack, is the "dynamic ability", and authority a good movie has to offer...and a sound system needs to portray that more than anything!...that and dialog inteligibilty and lack of coloration.
