I know this is an old thread, but I also have an older AP PSL-C2 that I use for a rear surround in my present 6.1 HT setup. This speaker was initially used as a centre speaker in my first attempt at 5.1 surround sound, 15+ years ago, and is still working great in its present capacity. I replaced the original 5.1 surround system with a Polk Audio RMS6750 set about 5 years ago and the Acoustic Profile centre speaker fits in great as a single rear in a 6.1 HT setup.
Like an old 'Timex' . . . it just keeps on ticking !
