    Hi Dr Toole -

    First and foremost thank you for all your contributions to our community/hobby/passion!

    I'm building a new house and for the first time will have a dedicated 26x15 theater that I'll use for 70% home theater and 30% music.

    I've got two F228Be's and haven't purchased anything else speaker wise for this room. I've traditionally been disappointed with in wall soundstage presentation, but I felt it might be wise to reach out to you and get your impression on using my F228Be's in a baffle wall and what, if anything, can be done to preserve soundstage depth/width in this type of implementation. It'd be great to go with three identical F228Be's across the front behind an AT screen, but I'm concerned of the trade offs that will occur.

    If there are any paper's or research you've done that might help me out I'd very much appreciate you passing them along. Thanks again...

    Hello Dr. Toole,

    I think I just discovered more unexpected side-effects of data smoothing in frequency response measurements. The implications are such that the assumption of a direct-dominant sound-field for mid and high frequencies in the cinema may fall apart or at least need to be modified somewhat.

    Unfortunately, the private messaging feature here has a character limit, so I can't go into detail without sending a bunch of short messages, which is stupid. I'd rather not post this on the public forum unless we make a new thread for it elsewhere. Another possibility is that we converse by private email. My address is: [email protected] if you want to go that route. Either way, I'll need a lot more than "1000 characters", and some images will probably help me explain things better too.
