Thanks for the quick reply. I don't think the piano has been a problem so far - and in any case I don't think there's much I can do about it as we like having the piano in there and don't have another room that would be suitable. Currently my speakers are right in front of the piano and I'm not aware of any adverse effects (perhaps I just have cloth ears). With the more uniform sound field should I expect more or less "imaging" than I would have with a more traditional out-in-the-room arrangement?
Next question: It seems that all the 7 Pi speakers are identical except for the woofer - is this right? If so, are the sound quality differences between them relatively smaller than between the two-ways where the woofer is crossed over higher? I'm trying to think through the economic tradeoff... I like to listen at moderate levels with headroom for the climaxes, but I'm not often looking for the levels of SPL your systems seem capable of.
Finally, could you send me a copy of the 7 pi plans, please?
I appreciate your help,
