what about 2" driver crossover with protection.

 

[mhtplsh]

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.

Use first circuit but with IRFP150 instead IRF540 for 2 inch driver.

Thanks Apex.
IRFP150 is not regular device.
If possible, kindly suggest other equivalents.
is it possible to use two devices instead of one for handling high power?

IRFP140, IRFP250...

Thanks Apex for suggestion.
i got IRFP150 supplier.
But i have also seen your crossover with bulb in series protection.
How will u compare by quality & protection of bulb type with Mosfet circuit?

Estimated Mile:
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.
ATOM
