4th Order Bandpass for two 12 Q's?

Recommended Posts

Anyone have any experience with FI Q 4th order bandpass boxes? I'm thinking about doing one for two FI q 12's. I've heard they really help to eliminate trunk rattles when you port them through the deck. I have 2200 RMS to work with.

Yes, they will work in 4th orders. Trunk rattles are only gone if ported through the deck or pass through. If still firing into the trunk, they are just as bad as a normal sealed or ported setup.

Thanks,

Scott

Be careful with your design to optimize the passband to fit your goals.
