They did however sell out.
Why do people always assume companies "sell out"? Usually it isn't the case. Most often these companies simply can't survive because people don't want to buy the $300 high quality Made in the USA product when they can buy a "1000W" product made in who-knows-where in some sweatshop with poor quality for $100?
It's a sad fact that too many people just see the absolute price and flashy designs with high power claims, and couldn't care less about the quality they are getting or where the product is made.
Companies like ADST (Orion, a/d/s, Precision Power), Soundstream, and many others have met the same fate. They never "sold out", they just started going under and some other company came in and bought up what was left just so they could continue to use the name.
Heck Orion and PPI were even separate companies themselves way back when, a/d/s came in to buy them out and then even ADST started going under and DEI picked them up after that.
The larger companies like Kicker, MTX, RF, etc. have kept going, mainly by themselves taking up Korean and Chinese manufacturing to cut costs and stay competitive. It's not that good products don't come out of those places with the good brand names on them, tons of these products are quite good. But despite power and technology increases, the days of hand-built amps with mil. spec components, made-in-the-USA are long over. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif I mean how many companies offer that anymore?
I don't want to sound too propaganda-ish but what I'm saying is true. And it applies to everything from car audio, to home audio, to home appliances, to virtually all consumer products. Consumers are typically simply pennywise and pound-foolish as a whole. Not everyone is like this but the majority would appear to be, and it's that majority that dictates what gets bought and what companies survive or go under.
