The best speaker you ever heard?

In my opinion, the speaker is by far the most important part of the audio system. After all, it is the only part you hear. OK, the other stuff really matters a lot, but without a great speaker... No go.

I am a bit 'speaker-obsessed' I guess, and now I am wondering: What are the best speakers you have ever heard, and what made them the best?
In my system the Quad 988 is the best I've heard. However, I would like to hear the OHM F's (owned from 1975-1989) and Apogee Scintilla (owned from 1989-2001) with the electronics in my set up now.
I now own a pair of second hand Ocellia Tilias. I think the manufacturer has discontinued them in favor of the Celia. In my own home, they are the best speakers I have owned since, due to financial woes, I gave up my Clements RT-7's.
Driven by a newly acquired 50 watt 47 Labs Gaincard, I strongly believe they will be chez moi for a long time.
They are highly room interactive, so positioning them is an adventure and a learning experience, since they exhibit some of the characteristics of direct/reflecting speakers.
They are a resonant cabinet, single driver design. Accuracy without sacrificing musicality, imaging, they have all that.
I can't wait 'till I have owned them long enough to feel I've reached their full potential.
While the 1A, with the outboard crossovers, may be better still, the 1B is as good as I've personally heard. There may be speakers that do this or that a wee bit better, but the Kharma bests them all by being *consistent*. It excels at everything, fails at nothing.
just got back from the audio show in Montreal and I would
say the best was the 989 Quads.

Most speakers have anywhere from 3 to 10% distortion.
The quads have a measly 0.1%

Kinda redefines the word clean and acurate.

They did sound quite amazing.
