Seems like I've narrowed down my choices pretty well now. I was just wondering why you didn't choose to use a PiAlignment for the Theater series? (havn't checked out the rest). I just did a quick check of the internal box volume used and it just seems to be very different. Is there any reason for this? The PiAligned Delta 15 and the box used on the Theater series didn't have much change in the transfer function between each other, but its quite a difference in box size though.

Thanks!
