Soundstage and explosive dynamics?

@csmgolf 
More stupid from you. No surprise. I'm guessing you've never even listened to Tools recorded work. Dynamically compressed doesn't at all describe it. Or DCD for that matter. 

@shadorne 
Multiple 15 inch drivers with 4 inch voice coils is borderline absurd for a normal living room. Nobody has of yet explained to me the benefits if trying to accurately move a hulking, heavy cone when smaller, lighter cones tend to behave better with just a few watts through them. Isn't there some virtue in a driver that will faithfully reproduce bass at 1 or 2 watts? I'm a lot more interested in drivers that will produce accurate bass at a half a watt than I am in drivers that will make crazy bass at 100 watts. No matter how you cut the cake, mass is a limiting factor in dynamic performance. Massive SPL's isn't broad dynamic range. It's just loud. How good is the bass at 35dB? 

^ There are plenty of large cone drivers can be driven to high levels with low power.

Many of the ubiquitous 3-way, narrow baffle, ~$3k towers can do dynamics fairly well, but I haven't come across any that can produce sound with the sheer scale of something like Klipsch Cornwalls. 

Question is do horns, generally speaking, produce life-like dynamics or exaggerated 'life-unlike' dynamics ?
As I understand, 15" woofer is difficult to make fast, maybe couple of 10" - 12" would be better ?
I would not expect any $3k speakers with any source and amps to give me a real scale, $30k would be a more realistic figure, I guess.
Having said that, I read some review of the Gryphon Diablo 300 integrated where the reviewer, after he had done his tests, tried this $16k integrated with $500 Elac monitor speakers, just for fun. He was close to shock - he didn't expect them to be able to play like that.
Speakers need great amps.

....because everybody wants gigantic, hulking crates for speakers, a big honky sound, and 110dB, right? This doesn't strike me as a debate so much about dynamic range as it seems about just blaring, deafeningly loud regardless of the quality. 
The foundation of excellent imaging is flat response across a broad range of volume. You cannot have excellent imaging without that characteristic. Huge speakers are very well known for sonically falling apart when operated below their optimum power. Speakers with smaller drivers remain much more coherent across a much wider power range at the cost of some dynamics at the their limits. It's a trade off and very few speakers deviate far from that truth. That's all I'm trying to say and have acknowledged here.  

Not going to comment on horns here because do not have enough experience beyond PA systems to add any value.

I have heard some impressive dynamics and excellent imaging from medium sized tower speakers with cone drivers that can be had for under ten grand new or used.  Many suggested here already. Here’s my list:

Focals - 1038 Be II or Sopra 3 - used
Wilson - later Watt Puppy or Sophia models - used (good choice IMO)
bigger ProAc Response models - used
PMC - Fact 12 - used (pair on Agon now just above your budget for nearly 1/2 price new, FYI)
Monitor Audio Platinum 300-II - used
Vandersteen - Quattro, maybe, preferably CT model
Revel Ultima Studio 2 - used - very good with right amplification 

none of these are going to be as efficient as horns of course, but you will not need a monster amp to drive most of them to achieve what you are looking for.  I don’t know what you are using now, but these are all very good for around ten grand, give or take a few big ones.
