Killer Floor Standing Speakers under $4000 for Rock?

I had some tekton 6.5t monitors on rigid stands with good punch and sound. I also tried some Tekton mini lores, not for me as they were too refined with no punch.

I still stand by my ProAc studio 148 recommendation, which I am using in my main setup now with soundocity sev9 outriggers (another strong recommendation). After 9 months of use (ProAcs take a while to break in) I believe my 148s sounded like the used ProAc studio 125s I had in my room for a while but the 148s have much better bottom end with the 2.5 way design. The 125 / 148 sound just gets rock and many other musical components like single and double reeds, drums and cymbals, etc so very right, plus the classic rock midrange while listening to floyd and similar bands has been mentioned in many reviews. 

When I read the title of this post and see "kick ass" and "high volumes", I'm thinking only a higher sensitivity speaker will be suitable for the poster. A 3db increase in loudness requires a double of the power or a 3db increase in speaker sensitivity. The sensitivity of speaker recommendations here range from 87db to 104db, both spec'd at 2.83v @ 1m, however both are 4 ohm speakers, so the 2.83v is 2 watts. A 1 watt rating will be 3db lower, 84db and 101db. It's been noted in another thread that while listening at an average of 75db, peaks were measured at over 100db on classical music. With rock/fusion jazz at high volume I have no doubts that peaks will be over 100db. Now listening at 3m and using that speaker with the lowest sensitivity would require over 200w for 100db and over 700w for 105db. Obviously that speaker is a poor choice. The speaker with the highest sensitivity would only require about 5w for 100db and about 15w for 105db. These power estimates come from an online calculator that factors in use of 2 speakers and in a room, not anechoic chamber. IMHO, the poster should use speakers with a sensitivity of mid 90's and above.

FWIW, the Zu Omen Def is a home speaker with the same sensitivity of those JBL's.

FYI, there's some 148s on ebay right now I've been eyeing--but they're a white finish, and my local dealer is just too cool to not want to buy from him.
(If its not obvious, I'm not, nor do I know the seller).

Google the Lirpa Labs Liberty Freedom 1776 A-FY.

I did and I'm thinking, LOUD, and lots of it.
