How many here heard the "Wall of Sound" Dead 70's

I saw/heard the "wall of sound" at the Hollywood Bowl.I remember the moat was covered up with this huge ass colum of speakers. I don't recall the year exactly but I do recall it was the best sound system I ever heard untill the stones "voodoo lounge" tour.

I saw them in Portland Or. in about 1974, the sound was very good and in fact contrary to the usual festival 'standing' in those days, they actually seated the crowd! The Coloseum was notorious for echo, but the Dead sounded sweet...

I saw them twice in '74 and once in '75. I may be totally wrong (and I am a dancing fool) but I thought I saw the name Marshall through the haze on those speakers.....were they Marshalls driven by Phase Linear and Mac, or was MY linear fazed?

Saw the famous "Wall" in Jersey City, 1974. Without a doubt, the cleanest-sounding big rig I've ever heard. During the music, you could whisper to your friend and still be heard. Yeah, those were Macs piled high. But not sure whose drivers were in the tweeter array and cabinets.

For those interested, there were 48 Mac 2300 amps feeding JBL drivers and Electrovoice tweeters. There were 641 speakers in the wall. 89 15" drivers 178 12" drivers, 320 5" drivers 54 tweeters. For more details see:
