Can someone check my work, to verify I am gaining maximum beneficial value from the bracing? From my understanding the bracing has two primary functions, other than structural support. To keep two panels from having the same resonate frequency, and to break up standing waves. Is there any adjustments I should make? Will I benefit from routeing the bracing edges round? Should I add a few randomly placed triangle braces? Remove the diagonals from the center brace? This is my first enclosure with matrix bracing, so I could have a big red flag in there and wouldn't know it. The enclosure is built for two SSA 15" Icons sealed, running 2000 watts total. The final volume is to the maximum sealed recommendation of 2.5 cu. ft. per sub, for a net of 5 cu. foot. The enclosure will be stuffed with 5 pounds of poly fill, to smooth out the response curve.

Subs are in stock and ready to ship! http://store.soundsolutionsaudio.com/products/us-acoustics-cw12d2.html

Glad to see you back on! Gorgeous work. Only thing I might add (which isn't nearly as relevant on a sub) would be to space them unevenly. General goal is to have no symmetry, but that is overkill. I of course tend to like overkill.

finally got around to vinyl wrapping some stuff for the buick. just need to dye them the right color.

I gathered the no symmetry, the second time around reading the cookbook. After cutting the braces. Doh. Will adding a few randomly placed triangle braces be a good bandaid at this point. Anything worth doing is worth doing right my opinion.

I don't understand the theoretical (and impossible) analogy. Everything is related to the physical and electrical design of the driver and then the enclosure it is in. No one answered the OP's question yet, because there isn't an answer that relates sound to any one characteristic. He asked: which actually has a pretty easy answer. The more travel you ask for in your driver the worse it will sound. This is less pronounced in a sub as Doppler distortion and such aren't so disturbing at low frequencies. But in essence the only general thing I can say about excursion is that the more you use the worse the response. If he actually meant extension (ie, frequency range) and not excursion (which it doesn't look like if you read the whole paragraph) then you could also make the generalization that the more extension the less possible output or less quality output across the same range. That is a more broad generalization though and taken out of context won't always apply.

Nice enclosure man, maybe that's why my sealed enclosure sucked because i didnt add any bracing.

Nice work J !!! Long time no chat.

Gracias señor nem. Looks like it's time to glue and screw.

Beautiful work, you should not have any issues aside from it sounding solid.

The opinion of others may vary but it looks like a beautifully constructed enclosure to me. That bracing should not be any issue at all with this being a sealed enclosure. I have seen comments where that style of bracing can affect output in a ported enclosure, which if true could possibly be an issue if one was intending to use it for SPL competition, but I can't imagine how it would be any issue ever in a sealed enclosure.

Flew in a 757 today. What a luxury!! So much more room, even in the cheep seats.

grabbed a gtx 1070, pretty sweet card

Lol

Got this to hang.

This is pretty big, as I have been a US Acoustics fan from day 1, and for there to be subs now is pretty sweet.
