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.

The Cerwin-Vega XLS-215 for about $1,000 is apparently a contender. They may be embarrasing to own, but not listen to. Google up a review or two. Perhaps with the left over $3,000 you can have some custom cabinets made.
I also am a Maggie 3.6R owner for years and use an SVS Ultra 13 sub with mine, but....

I am with Alpha220. Cerwin Vega XlS-215's or CLS-215's for under $1K will rock out a room that size and fill it with more bass than you will believe.

Keep the Maggies and look into the CV's like Alpha220 says..
The Cerwin-Vega's and ATC's mentioned above are a good idea.

At the high-end of your price range is the B&W 801N (the successor to the Matrix), which can be had for around $4k now used if you are patient, but they require bi-amping with powerful amps to really do their thing and are thus effectively more expensive.
Check out the Mirage OMD-28s at vanns. Bargain of the year, bass to die for, and when I crank Tool...I get goosebumps. Give them ample power and a couple feet around them, and you will not stop smiling.

My comparison between Magies 3.6 and B&W 801. The room size was 24 feet wide where speakers were and 26 long with another opening at the back end of the room. In total I would say over 1000 square feet of open space and as mentioned I sold the magies and kept the B&W's.....My amp was and is PASS x250
