I intend to use a 2241H 18" woofer crossing over to a 2251J (~9-3/4") woofer.

Through much experimentation, I found that I can get the 2251J "flat" down to ~110Hz. This would then put almost the entirety of the vocal range (begins at ~80Hz), and the first one - two sets of overtones all in the 2251J.

The resonant frequency of the 2251J is 61 Hz and it is mounted in ~0.4 cu ft and ported on the rear with 1-1/2" ID x 2.75" length of PVC.

So, what are the potential consequences of running the 2251J this low in a home setting?

Thanks
