Soundstage and explosive dynamics?

Hi, I’m looking forward to your findings. Wish #4 , certainly throws a huge curve ball ! Anyway , I heard a friends system, Westlake BBSM-15’s bi amped with a pair of Bryston 4BSST’s . He picked up an almost dead pair from a studio that had shut down . They were flat black . He refinished the cabinets and had the ( JBL ) drivers rebuilt at Orange County speaker . To me the older big JBL studios sound better than the new stuff. You will need a lot of power and some room treatment too . I saw Supertramp play at a restored theatre in Fresno when they first toured . They played “ Crime of the Century “ just like the album . I’ve been trying to capture that sound ever since! There is a guy named “ Chip “, he is on EBay as “ Rumdog”. He’s an old school JBL fanatic. He runs the 44XX series bi amped . Last year he was selling some Everest . He offered me a pair of JBL L 300’s restored for $5k. I’m at 559 392-5209. Text me for his number . He loves to talk and he is a wealth of knowledge . As far as trying you meet all your criteria, I started like you, and now my JBL’s are in the closet ( not for sale ). But to get it all and have the beautiful audiophile smoothness , Big System and Big Bucks . So on a budget , restored JBL , bi amped with a tube mid/ upper and SS in class A/B or class D. Run an active crossover and use room correction . And please share your results . Thanks , and Happy Listening , Mike B.

Wow thanks for the info . Glad I didn’t mention ZZ Top or Green Day “ American Idiot Tour “.  As far as “ Crime of the Century” , if you want to see a system stumble , play it LOUD ! BTW , I saw” Dark Side Of The Moon “ at the Cow Palace in SF , makes sense what you guys are sharing . Also +3 on the Tannoy’s , great suggestion. If I remember correctly Manly Labs , has them scattered around their shop . I’m glad  there is not a -#5 Wife Factor restriction at play 😝. Thanks again, Mike B , Clovis , Ca. 

Hi , this is great stuff . Question to the Horn Guys , you’re way above my skill level , so please share . Do the high quality horn systems move the air with the authority of underhung voice coils and massive power ? My experience is limited , but on this type system ,  can you feel the drum kick on your chest ? Is this an Apples and Oranges thing ? This is a sincere question based on my lack of experience . As a youngster my Grandfather had tube systems with big EV and Altec stuff . It was a sweet , room filling sound , but it didn’t create this sort of “ Air Pressure “ sensation that comes with good live sound or a huge SS rig . Please share as I’m here to learn , not pontificate ( I’m not that smart ). Also I apologize for stepping all over this thread , but with knowledgeable sound engineers and horn experts sharing , this is a wealth of information  . BTW it seems everybody agrees on Tannoy , that says a lot too . Respectfully, Mike.
