The 2235 gets low enough for music. The question I have is whether one on each side would be enough. In the JBL legacy it may be that the 4350/4355 is closest to the kind of sound you are looking for. It uses the 2235 in pairs, all the necessary parts are obtainable and the crossover has been adapted to an auto-transformerless version you could build.
The 2121 is the least preferable 10" unless you are locked into using the crossover from the 4343. The 2122, 2123 and 2012 would all be better, and in the 4350/55 the 12" 2202 might bring you closest to your drum kit sound.
Also, the proposed direction you have described reminds me of the Drew Daniels Ancient Audiophile system. He used 18" woofers, 2220's from 80 to 300, the 2123, a large format horn at 1200 Hz and a supertweeter. However, the enthusiasm sparked by his narrative makes it easy to gloss over the fact that he resorted to custom frequency response tailoring in his amps and used some very sophisticated and expensive equipment for final set up. Without those things it could sound really horrible.
All of the drivers mentioned require response compensation in h fi systems. You can provide this as Daniels did, in passive filter networks, or with external EQ, but it is probably impossible for most people to do any of those without the ability to do acoustic testing (i.e,, CLIO or the like). Therefore, you would almost certainly be more successful by replicating an engineered system, and the one which comes to mind, as I said above, is the 4350/55.
