that's pretty fascinating....I must be different because I care greatly how my music sounds, but could really care less how my TV/movies sound. Kind of makes me wonder how many in here do home theater mixed in w/ their hi fi.
I have an old Boston/Kenwood Unity and we never even turn it on....i do have a blue ray and a plasma though.
The Allison movie industry reference can confuse those grown up with the current Home Theater experience. Which basically made obsolete the "full range" speakers and replaced them with satellite/subwoofer set ups. So the East/West Coast thing today is pretty much obsolete. Subwoofers are expected to give the necessary punch. And satellites are able to specialize in the high and mids. Separated duties to keep the hot side hot and the cold side cold.
As for as my personal experience many years ago --- before the age of Home Theater or subwoofers in every pot, I would agree with the premise that within my budget range, there were few speakers with deep punchy bass or really high clean treble.
So I had to save up for an upgrade.
As I became exposed to live concerts and dance bands, that gap between home speakers and the live experience became obvious.
My introduction to the West Coast sound came about searching for speakers that that would give that kind of dynamic "realism" or "illusion" depending on the camp you fall under. I wanted that crisp bass line, sizzlling quitars where you can hear the strum and friction on the windings, soaring vocals ...
I made it known I was looking specifically for tight punchy bass and sizzling soaring highs. The SALESMAN introduced me to the Cannon TLS 1232s which he said had the classic West Coast sound. Piezo tweeter, 12 inch woofer, 12 inch passive. I demoed listening to Chuck Mangione/Esther Satterfield's Land of Make Believe. Oo-oo-oo ... brass, drums, chilling vocals. Sold.
If you do a search there are more comprehensive East vs West Coast threads, but basically this is as good a capsule definition as any:

Back in hi-fi’s golden age, there used to be hot debates over “East Coast” vs. “West Coast” sound — no doubt a tame forerunner of the hip-hop wars of the ’90s. East Coast speakers were thought to be smooth and mellow, with “concert-hall” sound best suited to classical music and jazz. West Coast models were bright and punchy — just the ticket for loud rock & roll.
