Listening position about 6ft, going to try them full range to see how they perform but most likely end up HPF at 60hz or 40hz, the bass is covered by the SVS PB2000 (12" with 500rms) so i'm not at all concern about the lower end. But usually I listen to music between 75dB to 80dB, at 54 I can't hear frequency above 14khz anymore. lol
I guess just about any 100w amp would do since they most likely won't use more than 50w, i'm not into concert level type loudness anymore, have to be in sane level and preserve my hearing.
