Do you mean the Tesla model, by Scientific Fidelity?

Review on Stereophile here (there are sections on specs and measurements also).

that's the exact one's i have ARO 666 and they're accompanied by two ARO 388.
all from a canadian made console branded Symphonic.

what's really strange is wiring, it appears one 388 is not high passed and series feeds the tweeter.

any published spec's on these?

is it possible that this wiring scheme when one considers the phase dots (i.e. polarity) with overlapping frequency ranges it creates a mid cut and crude loudness contour?

or does driver inductance serve a crossover function?

The tweeters in your picture are high passed with the series cap.

I donít have T/S for these, just impedance curves. Fairly flat with a resonance peak @ about 110 Hz.

Remember, it doesn't matter where in the series loop the cap goes.
