Guess I have to chime in, yet again. Every brand has had it's good, bad and ugly. Thankfully my 225W speakers were anything but bad or ugly. I listened to everything from classical (pleasant experience compared to many systems prior), rock, contemporary, big band, etc. etc. Only let me down once, after a major party and they were turned up too high, by a guest of course. Drove them into L.A. at the plant they were made. Both woofers replaced due to loose caps and one midrange due to poor performance (no surprise). Cabinets refinished, all while I waited!
I can't speak for any of the other models, but mine were awesome, hooked up to my Kenny amp and tuner and Dual 1237 TT. Bought them cause they were the closest thing to the L100, that I could afford at the time.
As for advertising, don't understand that statement since advertising is what sparked my curiosity. Maybe the advertising was limited to certain markets as there was no lack of it in SoCal, of course they were made there. Also, part of my decision was based on reviews and auditions against other brands. So no reviews? In fact you can find reviews on ebay, reprints from HiFi magazines of the time, along with reprints of advertising from the time. I'd take the "Private label" with a grain of salt.
I wouldn't hesitate to own a pair again. Not sure how I'd like them today, but I'd give it a go just to see. Have to be another pair of 225's though.
