Hello Mark, Thanks a lot for your reply. Yes, I think that by placing the drivers next to each other, this could lead to phase problems while increasing the SPL. by setting them 100 cm apart, the objective it to overlay the standing waves with a 1/4 wave difference constructively. When one is at zero-crossing, the other is at max amplitude. But only at one frequency ...
I am building a test enclosure and have the drivers already.
First, I want to use the horn sound and the free to air part. Second, the first driver should be as close to the throat as possible. With a throat area of 450 cm2 and a mouth area of 2400 cm2, volume 500 liters there are few ripples, usable up to 400 Hz and phase response looks good, smooth up to 400 Hz, -45 to -90. Can post the hornresp results, can't do it on this virtual machine. Will configure the 2 drivers in various ways and measure it ... best regards Marc
