Anyone remember a brand called Essence? There were a bunch of drivers in individual boxes stacked up in a staggered fashion for time alignment. I heard them back in, I think, '83. Driven by all CJ Premier amps and a Sota Sapphire table they were pretty stunning. $8K which was a chunk of change in those days.
Ditto Large Advents.
I had a pair of ADS. Don't remember the model #, but a 6" 2 way w/ a metal grill. Being a moron when in college I put them in my hotrod VW bug. Best damn car audio I've ever heard, but of course the extremes of heat and cold took their toll on the poor speakers.
My high end audio adventures started w/ hearing a pair of the Chartwell version of the BBC monitor in oh....'78 I think.
