Wayne, thanks for the Studio Two and Two Tower Plans. I've decided I'd like to build something with compression drivers and the horn parked on top. Then I fell over woodhorn.com, which showed some of your stuff with his (freakin' gorgeous!) horns on top.

I'm wondering what driver in which of his horns would be most suitable for a 2A3 or 45 amp. (Currently Wanna Glows - mutated Paramours which may become a 45 amp), on top of which of your cabinets/drivers?

I'm wondering if the Studio Two or 2 Tower makes sense, or if I should go to the Thermionic Three. I don't want to go waayy huge, but I do need efficiency.

It also occurs to me that if the Studio 2's are a good choice, one could start with the Twos, then add the horns later, disconnecting the Piezo or crossing it over as a super tweet. . . .
Keep your ears and your mind open.
