I just landed a Def Tech C/L/R 2500. I am very happy at how well it blends with my SDA theater setup. It contains the same types of speakers as the SDA's. Aluminium dome tweeter, sealed inclosure and a built in sub that can blend and contour to match the bass. I wanted something that could keep up nicely with my 2.3TL's and this fit the bill in spades. I'm useing a pair of SDA CRS+'s for the rear surround. Anyone else had luck with these centers?
