I move home often, so can't design speakers for a known room shape or size (and room treatments must usually be modest, too). Headphones and near-field listening have been the answer, but I miss having room-sized speakers. I suspect that horn/waveguide type speakers would have many positives in this situation, and I find MEHs especially interesting for other reasons as well.
I've not gone there because they would need to be large; unfortunately it is the somewhat lower frequencies, say at least down to 500hz or so, that would seem most beneficial for me to direct. Keel's equasion indicates something like an 80cm (32inch) wide horn-mouth for that, depending on what angle is chosen. Though they would probably need to play lower than their directvity, down to around 80-100hz, as I'd want to hand over to subwoofer(s) rather than need an additional bass driver.
However.. it occured to me that a lot of MEHs are quite sensibly sized around the actual drivers, taps and the straighter part of the horn. So, if the seconary flare and any round-overs were easily detachable and dismantlable (for transport, storage and when letting-agents come to inspect), the size might not be such a deal-breaker.
Though I've never built a MEH or even a big waveguide; there seems to be a huge amount to learn and test, especially if I'm on the wrong track.. For those who have experience of such speakers: do my hopes and expectations seem valid and reasonably achievable?
Thanks,
Kev
