I have a pair of old 12" SHIVAs in a sealed box ( from a bass list group buy). So far I haven't needed the bridged Haflers to drive them, the Technics (2.1 only )has proved adequate.
And my homemade TL's with their liquid smooth peerless cloth dome.
Suppose I need to get a center channel as I hate they way the engineers mix the channels now-a-days.
