If the specs are unknown? (8 ohm impedance)- they are 15" "full range" in Sunn/Fender cabinets- probably Eminence. I have a L&C meter at work, but I'm scared to hook up a speaker to the thing- I never have- and I wouldn't want to blow one up. Any home shop method with a sine wave and o'scope, perhaps?So I can add the woofer compensation to the excellent 2 way 1600 Hz crossover. It makes the CD horns sound wonderful.
Thanks
