They're wired kinda funny. Since it's 7 drivers, I couldn't get a nominal 8-ohm load. I wired the 3 in the middle in series and the 4 on the outside in series, and then the two runs in parallel (make sense?) and my multimeter reads 6.2 ohms DCR. (I don't have equipment for measuring impedance vs. frequency... yet.)
My question is this: the power handling claimed for these drivers is 10 watts RMS; 20 watts peak. (whatever "RMS" and "peak" mean these days.) They're also intended for full-range use, which I don't use them for. They're crossed over at 200hz, 12dB/octave. 12dB/octave is the right slope to keep excursion constant below the crossover frequency. This should help my power handling, right?
What I'm wondering is, can I somehow find out what the real power handling of my towers is without smoking one to be sure?
