Speaker City in Burbank makes their own speakers using premium parts - like scan speak woofers and tweeter; the same parts that go into Wilson and other top notch speakers. Their prices are much much lower, so I would check them out.
This is their web sight.

But I would seriously consider buying them here on the audiogon - you would end up with a considerably better quality for the same bucks ! Also when you upgrade, you can sell them here again and not lose too much - if you keep them in a good condition.
Used is the way to go - most people who buy at this level take good care of their gears, and it's safer than Ebay. No, I don't work for them, but since we are using their sight, we should give them something back too.
