Hi, I am about to start a home theatre build and my current surround speakers are much too deep for home theatre columns. 175mm x347mm x286mm. Well, I could build the columns out but would like to save some room. Looking for something a little thinner. Specs for my current speakers. Impedance (Ohm) = 4-8 Power* (W) long / short term = 100 - 140w Will be running off a Denon AV. THoughts on the type of speaker anyone?
