Dear Apex,
I understand from your post that Mosfet Xover are better than BJT based.
I have seen two types of Mosfet Xover.
Let me know the which is better?
Or advantages of both the circuits.
Or suggest which is best for using 2" throat driver.

Hi, I'm from Chile ATOM and would like to know if you have the possibility to send some model gia Acute wave line array to advance my project to design and build with you simplest possible materials and craft. I have carefully followed their proposals for the construction of low frequencies and boxes are very interesting.
Waiting for your response Sincerely.
