Hello Cal 37 13 and Adam,
Ordinarily I’d suggest choosing the higher speaker impedance if that’s an offered option. Ralph (Atmasphere) has pointed out numerous times that in addition to an easier load for the amplifier there’s less distortion produced driving the higher impedance.
It appears that the Double Impacts are an exceptionally easy load despite their 4 ohm impedance (probably relatively flat impedance curve and no steep phase angles). Cal I suspect that the Frankenstein’s 8 ohm tap would likely be sucessful driving the 4 ohm Double Impacts.
A phone call or email to Israel Blume sure wouldn’t hurt.
Charles
