I am still here still trying to work it out. Read your mid bass horns article again. Learned a bit more. You right about open baffle I once foolishly sold everything I owned to buy a pair of km30. They never sounded good until one day almost by mistake I drove them with a amp that was low frequency limited to just above the baffle size I had them in. I couldn't believe what I was hearing. For the first time they came to life. I still don't get how people build all these open baffle speakers and drive them full range and say they sound good. I agree that open baffle are useless in small rooms too. I just read that bit about someone saying they are suitable.
Anyway I still haven't started building. I have been reading for 12 hours a day for A very long time it seems. I want to get to work on a mid bass horn. But I am still no closer to knowing what would work then when I started. I have changed my mind a hundred times. I am going to drive all my channels from one amp now (except the tapped horns) with out digital correction. Purists insist this is the way. I still believe I will use tapped horns in the 50 to 100. My mid bass will be straight ~70hz horn. I was going to try get my compression drivers to go low but I have decided most likely I will build a cone low mid horn and then cross it at 1500 to a 1inch into a yet to be specified horn and then into a compression tweeter at 10k so no drivers are stressed.
I have some ev15 woofers and looking at a set of Goodman's audiom 80 woofers presently pondering if they would be suitable for mid bass duty's and a set of very beat up vitavox ak121 12" with a cracked frame even. But if the cones come out easy I could tig it up I think. I wonder if that would flatten the magnet though. There $200. I also have been collecting Philip's 12" drivers of different specs well pretty much all of them accept the Philip's AD 12202/M15 which I may snare tonite the most desirable because its the most efficient.(I didn't) What a waste of staying up all night. I will save my money for the Goodman's or vitavox I think. I wonder if these might make good horn drivers (Phillips)if I cut the whizzers off. They have big motors and light cones.
I am weary so weary of endless study. Even though I know the closest thing to the truth is here I don't come too often as you are so cynical it discourages from keeping going. You hate OB, vintage guys,more art dude(god I hate him too. he is like a living ad trojan) You seem to hate most every thing. But you seem to be the most knowledgeable guy on earth willing to share your knowledge so freely which I am grateful for. And I like the way you filter through the BS so proficiently.
I may be a audio moron unworthy of your time. But perhaps you could try to be patient and help me recover from my illness and build a Romy inspired horn system that works.
Though I have to say I don't think I have hit rock bottom yet. I still enjoy fetish-sizing vintage gear. I opened a set of Mitsubishi 8" eas coaxial's this week. One had never been opened in 40 years. That really blew my mind. Are well maybe I will never build anything worth listening too . But I will keep reading and maybe when I come up with a plan you don't think is moronic I will start building. I payed 29$ each for them! How I could say no! The Eas coaxes this is!
Sorry But I love being Audio Moron. Its so much fun building stupid irrational audio systems based on the fetishism of vintage audio parts.
Especially vintage tubes and open baffles and mostly horns of every shape and size.
I am over Evs I want to buy a table saw. I need some horns.
