I've heard that curved baffles work very well--with one big caveat: the sweet spot is focused into a tiny area defined by the curve of the baffle--sorta like a pair of virtual headphones hanging in space.

At that special little point, time coherence is excellent since all drivers are equidistant from your ears. Since the array is focused, you're also probably beating the 3dB decay rate of a perfect line source. The apparent efficiency (spl) of the array will be magnified, basically beaming its energy straight into your earholes.

Step forward, behind, or to the side of this zone, and all bets are off.

Thanks for the reply. I guess I'll have to make a separate set of "regular" speakers in case others are listening.

In the 7 (really 6) speaker bessel array, two sets of speakers (the closest and furthest pair from the center) are out of phase. What if these pairs were made to share an enclosure? I suppose their response would be similar to an infinite baffle. Is the infinite baffle a good alignment for speakers of Qts of 0.47? I could probably raise the Q to 0.5-7 by playing with the amplifier output impedence.

Thanks, Won

I have had this paper "The Line-Source Loudspeaker and its Applications" by Paul H Taylor from 1963 and have finally completed conversion from paper to pdf.

Some mathematical analysis, with some very illustrative pictures of comb filtering, and some practical applications.
