The best speaker you ever heard?

Odeon horns driven by Accuphase electronics. An image so big & texture so massively palpable it felt like you were transported into Patricia Barbers emotional center. Totally mind-blowing!

Probably the most startlingly realistic sound I've ever encountered was the Overkill loudspeaker at T.H.E a few years back. I've heard tremendous horn systems (in homes) tweaked to the hilt, effortless, clear, powerful etc but never in 30 years have I heard what felt and sounded like a live event like this. Even at great volumes the smoothness, coherence, and sound-staging were locked and breathtakingly free of cabinets AND THE ROOM. Not even MBL on their best day or the likes Wilsons or the big glass 8's were even close. Don't mean to bash but what that Manger driver and awesome bass cabinet were doing with DEQX was a game changer for me.

As an addition to my last post the associated amplifier being used to drive the Overkill loudspeakers was also by Overkill.

Reading through a few posts on this thread I noticed very few respondents mention the associated amplifier being used to drive the speakers that left such an impression. Perhaps, to the best of their recollection, past and subsequent posters can include this very valuable association to the experience. The reason being several of the loudspeakers mentioned I have also heard and, at the time sounded not so special. I heard the Focal Grand Utopia's powered with class A rated Spectral mono's at a dealership in Santa Barbara that sounded (for me) awful; shrill and painful. Yet with the right amp and associated gear the FGU's can sound exceptional. Electrical synergy that translates to emotional and component harmony is key. As we all know a speaker is only as good as what the amplifier is doing for it primarily and what the room is doing additionally.
