Wilson CUB I

Bummer it didn't work out for you. 

All the best

As the 2 gentlemen above stated, your amp will work fine with those speakers. Cubs are not all that hard to drive & 400wpc at 4ohms will work well. 

Good luck!

@rfnoise - They worked well in a 15' square room. I had them 8' apart, 3' from front wall, & listened (on center) approx. 8' away from them. What Arc amp do you own?

The cubs are really good speakers for the money (most seem to go for around $2000 a pair). Given the room, they will throw a nice soundstage. I had them in my dedicated room for a few years until they were replaced by B&W 802D’s. I’m currently running the cubs in our HT & still enjoying them.
