The best speaker you ever heard?

Gregm,

"The Synergies spec 95dB "in 3000 c.ft room". Hence ~90 (?) single spkr anechoic. The Amphi etc specs 86 single anechoic so, say ~90-91dB accordingly. That's ~1/2 the sensitivity this far."

I'm not sure how you made these calculations but seems like a lot of hand waving, not that my comparison wasn't either :-)

Like my grandaddy used to say......."It's a good thing we all don't like the same thing,........ cause everybody'd be after your grandma... hum.......best speaker I ever heard ... has to be Dale Carnagie seriously I've listened to the expensive ones, but I still like my ACI Sapphire II's with the Focal kevlar drivers mated with their Titan Sub

Well, I have heard a good speaker finally. One that does not have a boxy sound, that has a sharp leading edge, that has the pace of music, that images realistically, that has all frequencies arriving at the same time, and one where the speakers themselves vanish. The only problem is that the LSA Model 10 driven by the LSA/Exemplar components cost $80k.

Dracule -- a rule of the thumb: when driving TWO spkrs together inside a venue and feeding IDENTICAL signals, you get +6dB over the rated sensitivity of each spkr measured individually. But in the Synergies case, the spec is for music spl -- i.e. not identical signals, so the extra gain is less, say 4-5dB over the single spkr. So, the single spkr would spec 95-4 or 5= 90-91.
3dB: to go up (or go down) by three dB, you double the power (halve the power).
Cheers.
