4 Pi baffle cutout question
type: item
description: I noticed on the Eminence website where they specify a cut out dimension for the H290 horn of 10.3 inches by 4.9 inches, Yet, the 4 Pi baffle cut out document calls for 9.5 inches by 4.75 inches. Is there an error somewhere? Like maybe in my reading! Thanks. G.

description: The lip on those H290's is so thin, you want as much meat as possible, especially if you route them flush. In fact, we put a half baffle behind the sections that are routed. Anyway, my point is I like to make that cutout as small as possible, which is why the plans show a slightly smaller cutout area.

description: I've used Wayne's dimensions- works fine. I just put the horn lips on the outside and haven't routed or inset it. Plenty of room for t-nuts inside.

description: The cutout Eminence suggests is too large. We did a few with the Eminence suggested hole size way back when, and it barely left enough edge to put mounting holes through. So I measured the horn and came up with dimensions that would allow flush fit but still had a maximum size lip. It's 9-1/2" x 4-3/4". Eminence should probably update their spec sheet to use this figure, because 10.3 x 4.9 is neither convenient nor useful. It's too big.

description: Regarding Horn assembly, I'm worried about driver weight I just received a pair of PSD2002 and they are heavy! Is the Horn the only place where the drivers are attached? Thanks!
