A real W8C horn is designed to start and end a bit lower than MT121. So if MT121 is getting 170-1.6, then W8C would probably do 130-800 in the same scenario. The original design was the W8, which had 2 lo-mid horns and was over 3 feet tall. The doubling up made the mid horns go lower and louder, making them suitable for direct coupling with subs, for a no-kick-bin system. And it really worked, the old system in MelkVeg sounded lovely. I have doubts about the W8C, I've had them sounding nice by following Martin's instructions, but would wonder whether the single low-mid unit could get strained by too much "kick" energy in 100-150 range. I think the W8C was demand-driven: people didn't want to faff about with big tops boxes any more.
The horn design is subtle, using (as it seems to me) an oversize throat to allow a shallower flare rate plus some 1/4-wave, and a flat phase plug to pick up the high-end just far enough to meet the hi-mid channel but no further. Depending on how "authentic" your cabinets are, if this is not made exactly right the thing will just honk.
Of course you could use a midrange bandpass like I have with my TYs, but I don't think you're into bandpasses. Perhaps I can design you a midrange scoop?
