Previously my way bigger ported speakers were tuned to about 40Hz. That was too high to take advantage of my (!) room to anywhere lower.
Mine are tuned to 12 Hz, but the port gain extends an octave or two above that. Low enough to avoid audible GD. No port noise or chuffing either :)

Here is a super cheap dual driver subwoofer. I am prepared to duck. That company also has triple driver subs.


It's backordered, but what a price and Cdn$, for 12" triple driver Sub.
