[QUOTE="Kevin McDonough, post: 147351, member: 10402"] Re: New DIY Mid High lol very true. In my excitement at trying out this design and checking that the 810s for the 12" section would be a possibility, I forgot to check this. Having a look at some available horns, the only one I can see initially that meets the criteria of 90 degrees (edit: [I]actually, while the website I saw it on said 90 degrees, the actual ciare spec sheet says 100 degrees[/I]) with loading down low enough is the Ciare PR 401. However it then becomes a little wider even than the beyma horn, which was already wider than your original design. I'd have to make the cab around 80mm wider internally to fit the horn at the front which isn't ideal. Or possibly add a slight trap angle to the sides, a very rough scale drawing says around 6 or 7 degree sidewalls should keep the baffle for the 12" around the same but then expand enough by the front to squeeze in the larger horn, but this obviously then changes the expansion of the horn and will have an effect on the response. Nothing is ever easy! :lol: k [/QUOTE]
