In-line line-level high pass filters inside an RCA jack adapter.

For around $27 a pair, a cheap way to experiment.
They have a 100 Hz high pass, and a 150 Hz high pass. I would try the 100 Hz model first. Then set your sub crossover to around 80-90 Hz, and see how it does.

I did and it was like wrapping my speakers in a wool blanket.
I hard wire such things, and use high quality caps and resistors.
However, a friend did use them once, and the weren't too bad sounding on a moderately revealing system.
The thing is, they are cheap, and easy to try. If he likes what he hears, fine, if it lacks, but shows promise, then get a higher quality crossover or hard wire one himself.

... and while they do work as advertised as a x-over, sonically they suck. Soundstage shrunk considerably and they overlayed the music with a haze/grain that was intolerable.
The RCA connections/case molding is such that they only accept molded RCA connectors. I had to remove the shell to make room for my AQ and Audiomagic IC's to fit.
The concept is good and if they implemented the circuit with better parts it might be a successful product but they are aimed mainly at car audio enthusiasts.
I have two SW1's if anybody wants to try them...
