phase inverted preamps...about

I believe phase inverted and polarity inverted is two differnt things. Before switching polarities on speakers or amp better research info on the phase inverted pre. Hope this help.

If your speaker cables consist of two conductors made the same, just that one is marked red for positive and one is marked black for negative, then either way you invert phase you will still have one wire from the + amp terminal to the - speaker terminal, and one from the - amp terminal to the + speaker terminal. It makes no difference which wire is marked red and which is marked black.

Most people...if they do it at all, make the switch at the speaker end for no other reason than convenience I would think.

Just what Sogood51 said. Much easier at the speaker end for me.

Rewind to Clio09's observation about the leads being reversed from the crossover to the woofer he pulled on the Spendor 7/1's. Various crossover designs require a phase inversion on one of the drivers (usually the mid-range) to maintain overall phase cohesiveness. Check out the Loudspeaker Cookbook for reference. There would be no reason to invert your speaker leads in this case. I hope that makes sense.
