Hello!
I'm looking at a 4th order bandpass sub with a JBL 2240H, but a simple bassreflex tuned to 25Hz seems to give higher maximum SPL. Simulations were done in WinISD. Any suggestions on a design? Low frequency limit should be about 20-25Hz.I tried rear chamber=187 l, front chamber=41 l, tuning freq=56Hz.
Thanks!
