Reference strada one or two subs?

Many thanks for your helpful comments and experience. How do you have the tr3s wired and what are your settings for the crossover?

The TR-3s are wired from line outputs on my Aesthetix Calypso linestage. Hard to tell what the crossover settings really are, since they are not marked as to frequency, but I have the crossover knobs' pointers set at approx. 12:30, and with the "level" controls usually set at 11:30 in my system. Both are subject to experimentation, but I think this is a good starting point. My main amps are SET monoblocks with 845-type output tubes.

Really helpful. Thanks. Assuming its a linear scale and starting at 30 and ending at 180hz then a crossover around 12:30 should equate to something like 110hz or so it seems. My rel goes up to 120hz so I may try that first. Currently it's set around 80. Also see a tr3 locally that I may pickup and experiment with. Thanks again for the help.

You're welcome. I think you're right about the 110 Hz, or thereabouts. Be sure to check out that TR-3 before buying it. I had QC problems with a couple. Good luck.

Many thanks for the warning on qc issues. I will look and test carefully for sure.
