If money is tight, auction off the B139s and use the cash to buy a
real subwoofer driver.

If I did that, there'd be big holes in my present speakers.

They are basically a waste of good box volume.

Looks like I'll have to scupper the Nautilus copies built out of
plywood and car body filler, then...
