It works with SONOS Amp
Very pleased. Its works well with my SONOS Amp and it drives my outdoor subwoofer. Great bass in the pool courtyard.

Good product
Good product but the OSD speaker didnโt work well with it. Will have to change it out. But pleased with the item.

Way below expectation
Not working properly! The crossover isn't working. It sends the full signal to the inwall subs without removing high frequencies!

Did not work well using speaker line in/out function volume of bass was low.
Used as sub for addition to a 2 Channel stereo
