Sub w/a CJ ET3 SE

It all depends on what subwoofer you are using. There are many different ways to hook up a sub to a system. More info would help!

My current sub is a 14 year old Velodyne. Pretty much a johnny one note. Looking around I noticed Klipsch has wireless sub and REL can connect directly to an amplifier. Has anyone tried these connections. I just bought a pair of Aerial 5T's very sweet sound and the bass is pretty good but I want a little more punch at the bottom. A smaller sub would be preferable and in the $800 range.

Take a look at this SVS SB-1000. The owners manual will show you all the options for hooking up a sub. BTW,I think that the SB-1000 would be a good match with the 5T’s!

I have the same preamp on my second system and I use a splitter for the sub and it works great.

Yogiboy and ricpan thanks. My local dealer sells SVS and he may have that model on hand.
