S18H Build Pics

The build is very fast and easy. I have finished two and coated them in Herculiner (insanely durable stuff!) (http://www.herculiner.com/) and have been using them quite a bit. They are pretty big but that's not a problem for me. They honk a little bit past ~120-130 hz but I think that's because I still haven't got the 45 degree reflectors in them yet. I am planning on another pair since I have the drivers sitting around collecting dust. Also planning on a HD215 or two on top of each pair so I might not even bother with the reflectors. Overall I love the bass these make.

I was thinking of buildings one or two ,not a lot information on it ,look,s to have more output than a BR

Nice,i will be using it as a sub and a 1/12 for mid,s,high,s cross at 150 Hr,s

Yes. A pair of these spanks a 2-18" BR. About double the size (cu. ft.) though.

Probably saved an unnoticeable amount but its better than nothing. As for strength, it is not compromised in any way detrimental to the cabs strength. Holes running perpendicular to the panel being braced only compromises the braces strength when being twisted. No such forces will be exerted on the internals of a cab. (If there is you have other problems ) If you think about it the outer panels are only going to flex in and out. These braces should prevent that nicely.

Solid will be best, what you have there as a brace is the equivalent of making it out of thin sticks. When it comes to uneven pressure, consider what the cone is looking into. A lot of Horn cabs start out with uneven pressure regarding loading the cone. You can also deal for this with balance compensators across the mouth of the baffle.
