2405 or 2405H

[tweeter]

What is the difference between 2405 and 2405H?
Are the same tweeters?

[Uncle Paul]

The 2405 has an AlNiCo magnet, while the 2405H is ferrite. Performance wise they are considered the same. Dimensionally, the 2405 is much smaller in diameter than the 2405H.

Dimensionally, the 2405 is much smaller in diameter than the 2405H.The H's ferrite magnet is larger but the baffle hole and mounting screws are identical.

Exactly. Here is a link to the Technical Manual for the 2405H: http://www.jblproservice.com/pdf/Discrete%20Sales%20Models/2405H.pdf

If you design to give clearance for the 2405H, then both will fit just fine.
