[Cali_Screw 10+ year member]

hey every one...

So i began a build for my Two JL Audio W6's. I am going sealed on this enclosure, and it will be a up fire design.

Here are some photos of the progress, Some one had mention to me that i need bracing can any one help me determine where to place it?

And Also another had mention that i am probably give them to much air and i will lose output and gain SQ is this true?

(This cut out area is for a seat bracket that i must build around...)

What size woofers are they? How many cu. ft. per chamber? Extra bracing would help out a lot though, but as short as each wall is, it probably won't be necessary.

Sorry i didn't clarify that.. The subs are 12" and the box is roughly 2.5-2.7 ish (1.25-1.35 each) in cubic feet.. its hard to get exact measurements being half wood and fiberglass...

Also have you heard to much air kills output? i mean the 12w6 is said to need 1.25 per sub..

If your giving them 1.25-1.35 cubes each, and spec is 1.25 cubes... your WELL close enough that it'll be fine!! shouldn't really need bracing provided you get at least 1/2 thick with your glass, esp not until you hit the 2.0+ cube sizes (Per sealed / ported chamber)
