The best speaker you ever heard?

Martin Logan Statements (powered by Cello) long time ago. Recently, A-Physics Medea (driven by S-Line Kraft monos). Aural memory failing me, I can't chose b/tween the 2, sorry.
Quite a few speakers suggested above I'd like to hear though...

Detlof, I'd add "...driven by Jadis 80" to your recent post!

Looking back at this thread, I wonder at the validity of my suggestion(s). Speakers, being at the end of the chain, are definitively system dependent -- apart from their inherent engineering quality, ofcourse.

I wonder whether I have really *heard* giga speakers I have listened to play at their utmost... (commensurate source, pre, power, etc). At the end of the day, I think not.

To do justice to the thread, I should revise my post from months back to read: speakers I have heard playing better the best tunes I remember" -- i.e. NOT the BEST, just better than my personal (benchmark) system.

Cheers!

Goodgorl: the jbl's are excellent players, but not full-range (i.e. not intended for home use)-- or am I mistaken?

This Apogee "Synergy" eulogy vs Analysis "Amphitryon" just caught my attention. It's intersting to compare published specs referred to above by Dracule

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.

OTOH, Synergy rates impedance at 2.5ohm, rather tricky (but much better than the Scintilla); "you only need 30 watts/channel" yeah, and how many volts, and a hyper stabilised circuit:).

Amphi specs 4ohm which is even more benign for the average amp -- so, on the face of it much easier to drive.

Dracule tells us the Synergy hits 110dB spl (in room, both spkrs driven, I assume?). Similarly, the Amphi would require ~100W from a normal amp to reach 110dB spl (in room both spkrs... etc).

Synergy FR specs 20-25kHz (stereo?, in room, remember). Likewise the Amphi, but single anechoic. Both specs are elusive at best... i.e. how many dB down or up (unlikely) at 20? But at face value, the Amphi seems to spec better in room, both spkrs driven.

Basically, I've heard neither of the two (or if I have I don;t remember it). Just putting some thoughts on screen.

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.
