PMC IB1 and room size

I just put a down payment on a demo pair of these. I still have not yet heard them, but the price was so good, I'm not worried about getting my money back if I don't like them (tho it's interesting I've never heard anyone say anything bad about them!). They seem ideal for my needs, but I'm a bit concerned they may be a bit much for my room.

My room is a specially-constructed trapezoidal room -- about 225 square feet. Short ceilings, but heavily bass-trapped. Any IB1 owners here want to chime in regarding whether or not this is too small a room for these speakers? Do they play well against the wall (I've heard they do)?

Thanks!

www.audiocircle.com - There's a Bryston/PMC Owner's Circle.
The DAC-1 has really nice mids with the 4B-ST - electric guitar rocks in this setup IMHO. I've tried this exact setup but with the analog bypass of the SP-1.7 as a pre-amp. You may find less bass with the DAC-1 than other DACs such as Bryston's DACs and Bel Canto DAC3. This may work well since you have been using bass traps. I think you will be pleased.

The bass was less boomy (not that I found them real boomy with the ST) with the SST and perhaps reached deeper, although this may have been masked with the ST. Mids and highs were a touch fuller, but not too full. I've recently also added a Bel Canto DAC3 to my system (analog bypass input to the SP-1.7) and the bass is just crazy good. For more comments you might want to look at audiocircle's Bryston/PMC newsgroup (I moderate this newsgroup but have no no financial relationship with Bryston nor PMC). I also bought my IB1's without listening and they are the best speakers that I have heard to date.

I have a pair of IB1's and an IB1 center in a room of the same size as yours and they are fantastic speakers. Mine are against the wall with no problems. When you are ready, the 4B-SST is a huge improvement over the 4B-ST with the IB1s.

My room is about 13' x 18.5' - a little bigger than 225 ft^2.
My speakers are on the 18.5' side, 8' feet apart, shifted to the left side of the room. I luck out on the left side as there is a small opening which seems to take care of reflections. The right speaker is far from the right wall. I have a small sweet spot for music. I tend to listen with the lights off and my eyes closed because the speakers are pretty close. My center is the IB1-C and quite often I also listen to some music in PLII. I have heavy curtain behind the listening position. Everything is crystal clear and the bass is extended and tight. Although theoretically not a perfect setup, in practice it works well. I know of a very knowledgeable Bryston/PMC person who has used BB5's in the same setup with great success.

Hopefully I can post this link which answers a lot of questions that you have. The IB1's should be toed-in and this link contains instructions plus a lot more info about room size with PMC's.
