    ST-120. Which tap for which configuration. Empty ST-120. Which tap for which configuration.

    I have 3 sets of speakers.
    They sound awfully good together with each making up some of the differences lacking in the others.
    They are all 8ohms.

    In one configuration, all paralleled, I get 2.3 ohms.
    In another, (series/parallel) I can get 5.3 ohms.

    Any ideas which configuration would be best, and at which tap?*

    Thanks gang.

    *I have also tried using a 4 speaker switching box with 5 ohm protection, but it really soaks the life and volume out of the speakers when activated.

    Sorry if this sounds stupid, but sometimes I are.

    In general, the configuration that gives you the highest nominal impedance is easiest on the amp. Tube amps are more tolerant of near-short conditions than SS amps, but still not very happy about it. And what you read with a VOM is a static resistance condition, whereas Impedance varies across the audio spectrum.
