Hi there, I've been messing around with hornresp and simulating a tangband w5-2143 horn. I'm aware that the compression ratio shouldn't normally exceed 2:1 for high Xmax drivers, and port velocity shouldn't ideally exceed 14 m/sec. But given this is a 5" full range driver with a Xmax of 2.5mm, how high can my compression ratio go?, Is the limiting factor throat velocity?, can I simulate total harmonic distortion?. Currently it's compression ratio is 8.90:1 but it's throat velocity is only 14.5 m/s (at 30 watts). I know that at 30 m/s a port hole on a reflex box will begin to seal over and not function, but my question is will my horn destroy the driver or will it sound horrific?. The reason why I have even bothered to ask is because I saw plans for a XKI cabinet for the w5-2143 here: https://www.diyaudio.com/community/threads/xki-xs-ab-initio-karlson-6th-order-bandpass.268524/
And I would guess that it also has a high compression ratio.
