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

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:

Like, wow man, that IS a wall of sound!

I attended about 10 shows with this system and don't think I've heard it's better yet. A few shows latter on they experimented with surround in a delayed system covering the hall.Anyone hear this?
