Help with used "rock" speakers under 4K


Hi to all,
I am new on this board and would like to ask for speaker recommendation.
Looking for used speakers, under 4000.00 for listening to rock music ( loud and deep bass)
For other music - i got the magnepans 3.6r
my room is about 30x35 and ceiling 20ft (open to the top)
I have search the forums and came u with couple choices:
- B&W Matrix 801
- Aerial Acoustics 10T

any other suggestions?
Thanks a lot.

If you like the Magnepans (I am a Maggie owner) trading them in to get some 'other' sound is not going to make you happy if yu like the maggies except for wanting some extra thumpability to rock out at times.
For 4 grand your could buy a Fathom. or a pair of REL.
those are the brands subs I would recommend to add to a 3.6
For the best electric guitars ever: Zu Druid.

For instance Jim Suhler and Monkey Beat, "Tijuana Bible" at a really good volume is to die for.

In that case a sub is mandatory: Zu Method in my case.

thanks,
i will keep Magnepans - just planing to get another speakers with more "air moving".
looking at past threads - another option i see is Thiel 3.5

only problem is - maybe someone has experience with large room
The Aerials are nice speakers and worth listening to. I would also suggest you listen to the Vandersteen 3A sigs. They will, with power behind them move a lot of air. I tried a pair as an alternative to my Maggie 2.7s and they moved a lot of air. I couldn't afford to keep both so ultimately stuck with the Maggies.
