Yes, but if you could make it broadband enough, it might function
effectively as a filter. IE, remove a broad notch from 300 to the mass
rolloff of the horn. Just thinking aloud. What about a front
compression chamber? That would seemingly be the most obvious
acoustical lowpass. It might be sonically acceptable if enough care is
taken.
Back to your original idea, perhaps a simple 2" of rigid fiberglass
would do the trick - like corning 703. It'd be easy enough to try at
least. The absorption factor of fiberglass is easy to predict, just
look it up. My worry would be that the sound would be overdamped.
Interesting challenge.
