I did RTFM (!) for the two I have at home right now, they are waay too convoluted (written by chinese, with english as a second language??), & waay too much information I that cant fathom, , , thats why I'm here.
Mainly the higher freq's (I also worked around fighter jets for 4 years usaf = ejection seats, jet engines started the damage, dozers stepped in for the kill) The 'Technics are '3 way', have 12" woofers, I can 'feel' the bass.
I think a lower end av rec, (4 or 5 hdmi in & one out) (& a simple remote!) (phono input, I have a decent pre-amp for one) & something to 'boost' the sound level is all I need/want. Any more, I cannot appreciate the 'quality' of the sound, I dont need perfect undistorted sound, just decent sound.
Now I'm rambling!

edit: yes, those are my klipsch speakers. I have 'em about 7' away & the centers at ± ear level
