thanks for the input, gentlemen....
in looking at the Titan, it strikes me that Dr. Edgar has integrated into a single cabinet the basic array of 3 direct radiating horns seen in the System 100 in my original post.
the only photos of these direct radiators i've seen are the ones at the Vintage Audio Traders site and at Michael Christ's website. i'm pretty sure these are the same ones in both locations. i'm not sure who actually owns them. do you guys think M.Christ got some mdf cabs from edgar and veneered them? has anybody heard those models?
TBrennan-- how are you using the 'salad bowls' (what's your low pass/high pass for the input, and are you keeping them 'free floating' or mounted on something)?
where is a good place to find upcoming 'horn fests', shows, demos, etc?
thanks again...
