Room size suitable for which Wilsons?


My room size is 12.5' X 26' X 10' height, with the speakers on the short wall.

I've a pair of Watt/Puppy 8s on order, but was offered a great deal on MAXX2s.

Will the MAXX2s overload/kill my room acoustics? According to Cardas' ratio, I have to place the W/Ps 3.5 ft from the side wall, leaving only about 5.5ft from speaker to speaker.

I've written to Jfrech, and he's kindly advised that the MAXX2s won't be a problem, whilst another dealer said that its '100%' MAXX2s won't work. Jim Smith of Get Better Sound thinks it might be a little tight too.

Comments/advice greatly appreciated!

Great responses guys, thanks for all of them.

I'm made to understand that the bigger(biggest?) issue is bass overload?

A friend has suggested the Synergistic Research Acoustic Arts treatment for the room, I read up a bit about them and they seem to be quite the thing now for audio tweaks.

Would additional treatments like Auralex foams and diffusors on the ceiling be any more helpful? Does anyone have any specific product they've had experience with?
12.5' wide? This is very narrow. I wouldn't put any wilsons in a room this narrow. Wilsons are ultradynamic, and have a lot of bass. I would look into a a smallish pair of monitors for a narrow room, and place a subwoofer where it will minimize the room problems.
Err..that for starters isn't something I'd consider.

I listen to rock music at least 50% of the time, and dynamics are very much a consideration.

Thanks anyway, Goatwuss.
I can not speak about the Watt puppy 8's or the MAXX2's. But I have a very similar sized room and have had Sophia's in the room they worked fine as far as the low end goes...and did not over power the room.
Daisiu - With all due respect, and I do with you the best of luck, you can consider whatever you'd like. However, I've had smallish standmounts that were too large a speaker for a 14 ft room dimension.

Of course dynamics are a consideration, but any wilson speaker, except possibly the Duettes, is far and away too big a speaker for a 12.5' room dimension. If you are looking for somewhat even bass, you will need to spend thousands in room treatments to deal with the bass problems that you will get.

Clearly other people have had other experiences, but I've tried several times to put largish speakers in rooms that are too small, and it never, ever works out.
