RM7si-II or Revel M20 or .....need help please


My room is 12 feet wide, 18 feet long. There is a fireplace where the stereo would normally go. I only have room for monitors that will sit on a mantle on either side of the fireplace (firing down the lenght of the room), no more than 18 inches from the back wall, and maybe 24 inches from the side walls.

I have an all McIntosh system with the MA 6900 integrated amp, MCD 205 CD-changer, and MR 85 tuner. I listen to a wide variety of music.

Two intriguing speakers are the Joesph Audio RM 7si-II, and the Revel M20. I have read many good things about the M20 on other threads in this location, but not very much on the Joesph's. Can anyone speak to these or any other monitors (not B&W though, i've heard those) they have used in similar circumstances?

Thank you,

Thank you all! I believe the Joseph's have a port in the front. Also, don't the Revel's have an adjustment of some kind on them in case you plan to put them close to a back wall?

I would appreciate any other feedback you all can give. Thanks,
Yes, the Revels are rear-ported but have an adjustment control for stand or shelf-mounting. I use the stand-mounting option without any bass boominess. I don't think this control will make a big difference...the deciding factor is likely to be the room and the setup.
I have ProAc 2.5s which are rear ported and in my 11 x 13.5 room. The bass was awful for the first 40-50 hours and didn't get good until over 100 hours. It then got real good with amp, pre-amp, and CD upgrades. I'm able to keep the rear cabinet side 38" from the rear wall and 36' from side walls. I use a REL subwoofer and run speakers full range. The system makes beautiful music - it can be done with rear ported speakers in a small room. And, 4 out of 4 seasoned audiophiles who've heard the system agree!
Tomryan: I will be lucky if I can even put the speakers 18 inches from the back wall. So rear ported speakers might not work for me. Atleast you had 3 feet to work with. I will have to consider the use of a subwoofer though.
The Energy c-3 monitor with front firing port was favorably compared to the Revel at soundstage.com...and can be had for around $400 online...dont get me wrong...the Revel is a better speaker hands down...but the C-3 at 1/4 the price is a better cost vs. performance option....they look cool too...
