Might be good on a really large waveguide. But it would need to be very large to support 300Hz response.
I can remember people using similar drivers on really large round tractrix horns. That was not a good combination, in my opinion, because a tractrix horn that's large enough to support 300Hz is a laser-beam in the top octave and even below that. So the wide bandwidth was totally lost in that application.
But maybe a waveguide implementation might work better, since it wouldn't get beamy. There the problem would probably be acoustic loading down low rather than directivity up high.
