Cal3713, I agree with Charles that it seems evident that the 4 ohm DI impedance is a particularly benign one, with relatively little variation over the frequency range compared to most 4 ohm speakers, and little if any in the way of challenging phase angles. However two things can be said with a fair amount of certainty: Running the 8 ohm taps of your Franks into the 4 ohm impedance of that version of the speaker will significantly reduce the power capability of the amp, and will result in some degree of degradation of its distortion performance. And there certainly could be other sonic consequences as well. Personally, I don’t like the idea of introducing a known and likely significant compromise into the configuration of a system, on top of all of the unknown and unpredictable tradeoffs, compromises, and effects that are inevitably present in a system. And in a hobby where many concern themselves with things that are likely to be far less significant, even things like which way a fuse is oriented. Without a strong endorsement of the idea from Mr. Blume I would not even consider it. At least without the opportunity for an **extended** audition, and I would be hesitant to invest the time that would require given my suspicion that the result would stand a good chance of being negative. Best of luck, however you decide to proceed. Best regards, -- Al |
