Recently purchased a Seismic Audio 4x10 cab used for $100. I really didn't expect much, it was just a good deal and I had the cash to blow. The thing lists for $200ish on the Seismic Audio website. It's 800w at 8 ohms with horn.
I am absolutely astonished how good the thing sounds for a cheap cab. It's very deep and thick. Up until recently, I had never even heard of the brand. But damn, this thing thunders. I'm using it with my GK MB210 combo for a 6x10 setup.
Just goes to show another prime example that price doesn't always mean quality. If you guys get a chance to try one, I definitely recommend it. The tone compares to $500 "big name" cabs in my opinion.
I kind of had to swallow my pride with this. I've always had a slight disdain for "off brand" gear. This purchase has definitely caused me to be more open-minded.
