    Hello Earl

    That looks good! That would be a great combo nothing like a 12 on steroids!

    Hi Rob,

    Have you run any distortion measurements on your AMTs to see how low they can go ( before needing to be crossed out to a woofer )?

    Can they do 750-800hz ( with a 3-pole network ) ?

    Hello Earl

    Not sure if I did sine or impulse will tale a look. I used the ESS schematics as a reference. They used 18 dB networks in the AMT look at the schematics posted in the General Audio Forum also take a look at the link. Either way when I rerun them I will do a sine sweep to see what's up.

    I wonder how the Heil would respond in a sealed midrange style enclosure ? ESS used to make a model 1B Bookshelf that looks interesting.
