The KUBE needs to be in front of the amp. You might try the 102s without the KUBE, and perhaps boost the bass a bit.
Kef 102 Reference and Kube use without tape loop or preamp
Hi, I'm trying to figure out a way to use my Kef 102's and Kube for front speakers in a surround setup with a Denon AVR 1713 amplifier that has no tape loop or preamp in-out. Would it make any sense to place the Kube between the speakers and the amp speaker outs?
