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!

I think the DAC-1 won't be around too much longer. I really hope to try the Lavry DA10 soon. The DAC-1 is a good DAC, with excellent features for my setup, but my experience with Lavry converters is that they come closer to sounding exactly like the source than anything else I've heard.

Ryder:

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.

Jethro,

Thanks for your response. Now I know your IB1's are set up on the long wall. I knew these speakers need to be further apart from each other to create a bigger soundstage and as such, setting them along the short wall in a room of roughly 225 sq ft. is pretty tough. The IB1's I auditioned in the showroom was set up roughly 8-9 ft. apart in a huge room clear from side walls and you are right that these are excellent speakers. Driven by Bryston electronics(as usual),the bass is just phenomenal and full.

Mine will be 8' apart along a 12.5' wall, a solid 2' from the side walls. The front corners are treated with bass trapping and there is substantial broadband trapping at the reflection points, as well. I have a good feeling I can make it work! However, I may need to move my listening position back a bit since I get the feeling the IB1s don't like to be toed in.

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.
