Hello,
I've got a JBL 2384 horn with jbl 2451 driver. This is just a thought: has anyone tried pairing these with an 18" woofer? Say 700hz crossover?

Here's my idea: mobile 3 way system with compact boxes of 3 cu. ft. or less for easy handling.
18" midbass woofer to cover 80-700hz (Faital 18FH500) sealed box - 2.5 cu ft.
JBL 2384 + jbl 2451, 700hz and up
Subwoofer 18" sub woofer -- ported 3 cu ft.

I think that a "fast" 18 inch midrange/midbass is not a common woofer but I saw a few that may work:
Faital 18FH500
Peavey 1808-8 HE BWX

It seems like a light cone, low Le, 18" woofer in a sealed box should do well covering 80-700hz. Will at match the JBL 2384 horn?

thanks,
Herman
