Help with used "rock" speakers under 4K

ATCs make for the best "rock" speakers bar none..

That's a very large room. In my opinion, speakers that have a good dynamic capability and smooth power response with robust bass tend to be good candidates for a very large room (think "prosound-style but with smoothness and deep bass"). One way to get smooth power response is to use a big constant-directivity horn and a big woofer, and to cross over where the woofer's pattern has narrowed to match the horn's.

Have you considered something like the Altec Model 19? Long since out of production, the Model 19 is a high-output classic with very good bass and smooth power response.

Seldom available used, but within your price range new, the PiSpeakers 4Pi embraces essentially the same design principles as the Altecs mentioned above, but with more modern, higher-output drivers and an even better crossover. The designer, Wayne Parham, is a master. If you go for the 4Pi, get the JBL woofer and B&C tweeter upgrade, both of which are well within your budget.

thanks for answers
based on some suggestions please suggest me a good Sub that will go well with Mags 3.6.

Fafafion - ATC speaker , do you think it would be enough for the room ATC scm50aslt (i know its above my original budget, but if the extra 3.5K will make a good difference.... maybe)

Look into Cerwin Vega, I think that is a good fit for what you are doing. Very efficient and capable of pressurizing the room. No subwoofer needed.

I have owned Magnepan Mg3.6 on mye stands and B&W 801 matrix 3 at the same time. I sole the Magnepans. I have had many other speakers and only my Revel F52s bettered the B&W.

My opnion, get the B&W's. You will be suprised at how much resolution, imaging and bass presurasation you will have. Make sure you put them on stands.

A good pr should be about 2500 and if you dont hear what I heard you can sell them for what you Pd
