I agree,many horns achieve the criteria by only slight margins. They will 'work' But are nothing like the perfect infinite horns.The reactive quality of compromised non ideal horns concerns me but they still sound alright?
[quote] So a short horn on the front of a woofer is basically a front ported enclosure.
Certainly theres a point where the horn is hardly functioning - and there is the opposite extreme where it is functioning to its maximum potential[horns no one can fit in their house]
And often inbetween many basshorns like the labhorn[in large stacks]
For my home use 42hz 2226 horn,I decided the minimum sensitivity would be 100db/1watt,below that I might as well not bother.
Id love to buy some AES-its just that I think the anthology might be more useful and practical.
