4638 system uses parallel wiring,


so the SYSTEM z with two 8 ohm nominal drivers is rated as 4 ohms. I tested sensitivity with a single 2035H, ie one 8 ohm driver, connected to the amp. 2.83 volts, at the driver terminals, into a nominal 8 ohm z. But the v.c. DCR is 3.95 ohms. The 4638 system, with both drivers hooked up, was 2.0 ohms DCR, maybe a tough load for some amps, but who cares cause this one is being chopped up as a "donor" for woofers in my Pseudo 4 Pi Pro rear surrounds.
