Avalon Isis Advice needed


I fell in love with these speakers (walnut finish), but my dedicated listening room is only 11'3"W X 30'L X 7'10"H.
Suspended tile ceilings with cork floors over concrete.
Power: Goldmund 29.4 monoblocks (300 wpc) via Halcro DM10 pre.
Avalon recommends 3' minimum from side walls & I only have about 2' from side walls with toe in.
Will this work out for me?
Have plenty of room behind speakers & listen from 15' away.
Have 8' of space behind the sweet spot & can treat.
Any help is vital & very much apreciated by Isis owners.
Currenty using Sonus Faber Stradavari's, but just a tad too wide for my new dedicated room @ 25.5" W vs. 14.5" W for the Avalons.
Will have 4' - 5' behind the Isis (recommended by Avalon).
They also recommend 3' from sidewalls (minimum).
Have been using the Strad's on Adona 24" X 24" X 1.5"H granite with MDF platforms which tends to help placing the Strad's closer to the side & rear walls very effectivly - Will this help with the Isis?
Thanks very much to all!
Please do not recommend any other speakers to me, as I have made this decision on what I have heard & digested.
I only hope that my room is large enough to accomidate.

Try the Acoustic system resonators , these will blow your mind and will sort out your problem.
Richard: I do think that the room may be too small and you may have lots of problems. I would recommend calling Avalon directly, not your dealer, and letting them know what you intend to do and see if they think the speakers will work in your room. I believe they will be honest with you, they are very good guys.

Good Luck,

BTW, 15' away is way too far in that room.
Not sure if that would work. The bass output on the Isis is substantial. Have you considered the Avalon Time or Eidelon Diamond perhaps? Your room would need some very heavy treatment to deal with waves bouncing around.

If you sit 15 feet away from these speakers with only 6 feet of separation, your soundstage will probably be very distant and uninvolving.

I agree with emailing/calling Gary Mulder at Avalon. He has experience setting these up. Send him photos. My dealer had the Isis in a smallish room, and he did some major treatments to the walls.
