I'm searching, but can't come up with any parameters for them. Any idea of the efficiency, frequency range, QTS? Thanx.
I've heard the Fs quoted as 19Hz, and I'm betting that's close, due to the very loose suspension, which probably has a Qms somewhere in the 7 range, though it may have some age-induced variance. Assuming the AlNiCo hasn't gotten De-magged, I'd expect a low Qes and hence Qts. They say that the sealed box Leak used gave it a 58Hz resonance, and they weren't known as bass monsters, so I'm assuming something like a .2 Qts and an overdamped bass alignment (.6 Qtc or so). They'd probably be very fine horn drivers. I believe they had a breakup starting somewhere around 900Hz.
That's all guessing- I'm staring at these as well but just can't justify buying more woofers at the moment. That could change any time, as my dorky self is lacking in woofer-resistance fortitude.
