Hi,
My dad still runs a pair of original Legacys.
I might be a little off, but I believe their efficiency was on the order of 86 - 88 dB/Wm with a frequency response of 0.04 - 20kHz. In reality, though, he routinely got response down to about 0.035 kHz, with everything falling off rapidly below that (as is the nature of sealed, large driver enclosures).
I'll give him a ring to see if he still has the owner's manuals. If he does, I'll write again. I cut my teeth in the world of audio with these speakers, though, and I think I'm relatively close with my memories! Ah, the memories!
