HI "Hifiordie" I want to tell the readers here that this guy is seriuos and has some serious talent.Unluckily for him he has been bitten by the same insect that got us and is obsessed by horns, please do listen to Romy and try to balance your life before going too crazy. Now crazy is good!
The guy wants to glue the parts himself so he can turn them partially, like Anthony is describing but you do have to be careful in one thing: Bass horns do need to be massive, weight matters and materials matter, I have made several horns now, from 110 hz to 140 hz and all the way up, from MDF to HDF (very heavy) to Plywood and now walnut and maple for midrange horns. Don´t make horns too thin, keep them at least 1 1/2" thick. I am afraid you will end up with too thin maple horns and that would defeat the purpose.
Yes MDF is a mess to finish, it´s like polishing a turd... Your idea of 3D printing I think is fascinating, if you can fill them up with sand maybe that is best. NO finish needed.
160 hz is good enough for a start, as Romy claims here: The most important part is the Upper bass horn and the midrange horn combination. Give a close reading to Problems with horns Upper bass horn and How to select mid-upper bass horn drivers from the Audio Knowledge tree.
And no, pro drivers are not crap, JBL, Altec and almost all of them started as PRO drivers and imho have been surpassed by the new technologies and newer PRO drivers, so feel free to take a pick, but look very closely to the published specs.Rerurn to Romy the Cat's Site
