There is little to no market for undocumented DIY designs, however, I would imagine you would have more luck trying to sell a well documented DIY kit speaker like linkwitz, selah, northcreekmusic, etc.
The lack of interest in true DIY speakers is understandable considering the only feedback regarding how the speakers sound would come from the seller.
