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!
