Saw these on ebay. Custom made component set from a small company, they list them on ebay.

What do you guys think of these?

They're quality crossovers, which is usually the difference between different component sets from the same company (like MB Quart - the main diff between some of their comp sets is the crossover).
They really don't give any tech specs about the speakers or say anything about the materials used to make them.
