general box build

Bracing isn't really a worry. By double layer the baffle do you mean lay 2 sheets on the front?

yes 2 sheets. Helps strengthen the face. The subs especially large ones exert great force on there mounting wall. having more to screw into and the extra thickness really helps.

Have I asked you this before? Sorry if so. So on the side, unrelated to this topic, gimme your scoop! I personally use a higher level mid(for that noise) and oversize my sub enclosure by a(to embarrassing to mention) large amount. Reason for mention- after hearing the sound produced from my boxes and based on these listeners favoring rap. My friends(or so called customers if I charged for services) usually decide to donate a little more space than originally intended to achieve the sound. Now, my higher level associates building for customers to show or appease the more affluent enthusiasts ALWAYS use spec, understood! However, the other day my Cerwin VMAX 12" was mistaken for 2-15's by a individual familiar with car audio who overheard me being annoying with sound at a gas station. A compliment that rarely is given from a spec enclosure.

"do you always build to spec on your own boxes?" NO, it really depends on the subwoofer and the overall goal. I recently went from a 11 cubic foot enclosure for my L7 15s with 100sq.in. of port area to 13.5cu.ft and 200sq.in. of port area. The first enclosure was for daily street beating. It was doing 149db on the tl. The new enclosure is doing 153db. It is tuned to 1/4 wave format to the sensor. It is way peaky, but is what was needed for the SPl shows im doing. I also made a slide in port with 120sq.in. of port area for daily tune. The problem with a design like my current one to do both spl then go to a more SQish sound in one enclosure is it took a lot of testing, design and was not easy at all to construct. Most are not going to do that. Most want in the middle. Sticking more to the recommended specs ensures you are in safe limits of the woofer in a normal music environment. Sticking somewhere within the min-max is going to get you good sound and output. Simply changing tune to put it more in the range of a listeners taste is much easier and way less time consuming. Not to mention much cheaper to not have to do all the testing with enclosure size and ports. The manufactures have mostly done this for you already to give you around the best overall on loudness and a good sound.

That's what I'm talkin about man, I like your style! Thanks for the feedback. Ima avid tester too! Those dimension's sound like some I'd be rockin. For my own systems, I add the sub and cut it off at like 55Hz. Just for a lil vibration in the cab... Cuz thats the way I like it. I can imagine the sound your producing and would pledge that I'd like it.This is what I do for FUN!
