So I finally found the specs on my Yamaha bookshelves I've had in my dad's garage for like 2 years b/c I didnt know what to do with them.
http://www.yamaha.com/cgi-win/webcgi.exe/Specs/?gSPK00010NS-A738
Type Three-Way Acoustic Suspension, Magnetically Shielded Bookshelf
Driver Complement Woofer = 8" Hi-polymer Coated Cone with Inverted Dust Cover
Midrange = 4" Cone with Inverted Dust Cover
Tweeter = 3/4" Dome, Ferro-fluid cooled
Input Power Nominal = 70 W
Music Input = 140W
Frequency Range 90 Hz to 20,000 Hz (the 90hz sounds really low for something with an 8" woofer, when I play music I can hear bass so thats gotta be a typon on yamaha's part)
Sensitivity 91 dB/2.83v/1M
Impedance 8 ohms
Dimensions Width = 10-1/2"
Height = 16-3/16"
Depth = 13"
Weight 14.4 lbs./each
Hooked them up to my Sony receiver and this speakers are not too shabby, I really doubt they are even broken in, only time they are ever on is when I'm in the driveway washing my car, and since I dont live at home except for the summer they havent been used to much. They are extremely natural sounding , would this be something I could use for rears and get some Athen F1.2s and an Athena C1 center?
