Just curious if anyone has looked into doing a DIY version of the single 10" coax JTR and if it would be worth it? They seem to be extremely well reviewed by those who own them, and from what I saw from someone who opened one up they use a standard B&C 10FCX64 coax. Looks like that coax on its own is only 25% the price that the speakers sell for. The box is a sealed box 16x11x8, which seems simple enough. That leaves the crossover, which is what I don't know anything about. Is the crossover likely to be that complex and expensive that there's no point even trying to build something like this? Even if it was another few hundred to build a crossover it seems like you'd still be well ahead, though depends on where you can get individual components I suppose. Sorry if this is a dumb question, I'm not a speaker designer but just looking at the cost of the driver vs the finished product I figured it was worth asking if something can be done that will perform roughly the same.
