I've used them, I think Towncar has used them. There are no online dealers. The company was founded by former Phoenix Gold folks. Good people. Drop them a line via the website and they'll tell you where you can find them locally. If there's no dealer in your area, they do direct sales.
There was a thorough review on the soundbuggy forum.
Basically, the tweeter is pretty lively for a silk. Not harsh at all though. Mid is solid, especially for a woofer this shallow. Build quality is above average. For the price, I think they're great. And if you can't fit these, nothing is going to fit.
