Back in the late 70s or early 80s, i was in pacfic stereo,in houston.listening to jbl l300 and other top end jbl at that time.there was a speaker in that room, it had a cabinet like the l250 maybe larger,three or four way,multi drivers and it had l.e.d lights if memory serves at the bottom of the speaker for power input.they were highend,they struck me at the time as very good.this is vague,was it pradox,can't remember through the fog.
