Market 2 would be guys who aren't set up for producing the cabinet pieces but could assemble and maybe finish them. Then there's the new, retail speaker buyers. I'd guess the order of Market size from smallest to largest would be Market 1-2-3. Market 1 guys can buy either plans or flat packs, but Market 2 guys can't use plans....they have to have flat packs. Also, I doubt a majority of DIYers in either group would jump at buying $2400 finished BMRs, because the woodworking/building itself and the $$$ savings gained are a significant component of the hobby for them. OTOH, if you're potentially a retail buyer who wants to save some money and exercise your building skills a kit would be a great option.
I like your thought process here,
. Based on some prior comments though, I wonder (as I have yet to engage on a first-build, myself) about overall complexity. Using the BMR Monitor as the example, you have two distinct issues with the Baffle that raise the complexity level... perhaps considerably...
First is the shape of the BMR Driver and the routing required to flush-mount it. Though doable, this definitely is not the ideal means of learning how to use a router, or knocking those notches out by hand. But one step beyond this is where the extra bit lies: the enclosure for this driver which I would expect wants a bit of routing on the inside of the baffle as well (or perhaps some corner bracing?). Dennis has given us several tips about how essential this enclosure is to the final performance of the driver.
While basic information including just a schematic of the baffle with measurements, and XO schematics of the AA/AA+, Mini-Phil, and New-Phil would suffice for the Market 1 type above... I think a blueprint of the BMR may actually be required for a successful build in the market 1 category. Or access to a BMR that you don't mind tearing down.
(I did, I admit, pull the woofer on my Center BMR to examine if I could turn it upright when I build my equipment stand and free up my front wall. I don't want to do more than that, though!)
I suspect also that the port placement in the BMR is very specific and intentional.
