OK; sorry but I don't remember.

I was born with NO memory. I think it improved for a few years, but I'm 62 now...and I can't remember what I was going to write...

I too never used the transformers. I seem to recall I ran 2 (or 3?) in series and drove them with 150-Watts-into-2-Ohms tubed amps, c-j MV75s paralleled into mono. The Stratherns had raggedy--peaky--upper frequencies and sounded a bit 'hard', about the same as the Eminent Tech.-8 MR drivers do without a lo-pass filter on the top.

I know Entech, the speaker company Damien Martin and Keith Johnson and ? were involved in and made that fabulous 3-driver, servo-controlled subwoofer that Two Jeffreys Audio sold, tried Stratherns. They put a small cone driver (6"?) on the bottom to warm it and a ribbon tweeter on the top to make the treble sound decent. They gave up on that.
