SET Amp question

Rock,

Thanks. Yes, I have had several respond indicating that some better built higher power SETs have produced good results with some less efficient speakers even in lieu of a separate powered sub.

Is there anything that will minimize the speaker SET interaction?

In the case of speakers that are voiced to be used with high damping factor/low output impedance amps, such as typical solid state amps, I would expect that the tonal imbalance problems which were explained in Duke's excellent response could be significantly reduced by inserting a pair of Zero Autoformers between the amp and speakers.

I have no personal experience with them, though.

Best regards,

If you have questions about how an SET or other 'current source' amplifier will drive a speaker, maybe this link will help in understanding what is going on:

Thanks for the read Ralph! It would seem that the distortion spectrum or bandwidth is more important with respect to the preceived loudness then the intrinsic acoustic power? EG: to make a rig sound less forward one would strive to minimise odd distortions in the presents range ( 1500 Hz).
