Nice project! Very challenging indeed!!! As far as actual area of the diaphragm, don't forget that a traditional cone will have a larger area than a flat diaphragm of the same dimensions, but I don't know the dimensions of the Pioneers so you may be right. Also, my guess about the purpose of the foam blocks on the side act as a damper to reduce standing waves, while the textured surface reduces noisy spikes in the lower midrange from reflections inside such a tight little box. Obviously the vents are really the screened openings on the back of the cabinet. As far as the ribbon tweeters are concearned, if they are like ribbons I've looked first hand, they are probably sealed in the back & you really can't damage them from acoustic pressure or they would blow, whether the box was sealed or not.Superduper said:Here's the inside of the cabinet but it's not really going to show you anything. Here also is the backside of the drivers but it's not going to show you anything either. The round portion is really a whizzer cone, that is isolated from the flat bass section via it's own surround. The only way to see how it's constructed is to saw the speaker in half. Interesting note: The flat woofer, by spanning edge to edge instead of losing real estate to the radius', is equivalent to approx 8.5" round woofer.

Very nice 1 of a kind design. Also, re-edged speakers, of any shape are rarely as tight as the originals, no matter the skill of the tech doing the job so don't be disappointed if the Bass is not quite as clean as the originals. It'll never be the same but very close, all the same....
Cheers,
