    Curious on your motivation...
  2. Yes, all air is excited, and there is flow. Air moves, it is exchanged. Do you think pole vents and basket vents are there because air is stagnant? No, it gets moved around, that's what cools a voice coil. Even outside of the sub itself, it's not circulating the same dead air. If air moves, there is flow. It can change directions in a short area, but that's still flow. Get inside ANY seriously loud SPL vehicle, look at the box, and tell me there's no flow. We go to great extremes to make sure things are very smooth and gradual. Flow has direction. Which direction is this flow? Movement does not equal flow. Does the speaker cone flow? As for the great extremes you allude to, that is not for flow but to reduce laminar resistance.   While your definition is accurate, there are side effects to bracing. What happens when you stiffen a bridge by putting a brace across the lanes a foot off the pavement? Then you would be an idiot of an engineer. The Tacoma Narrows bridge was sufficiently stiff, but had the wrong resonance and not critical enough damping at resonance. It failed miserably. Better question for you. Why do some people have ONE box that does something and without thinking about the math or reasons then apply all the things they did in that box to every other situation? SQ people get judged at 90 dB, and often listen at that level too. I guess you're talk about dampening factors on amps now too right? Just like there are more people who want an SPL setup than compete the same holds true for SQ. To me it is all about the music. Look up Modal Analysis and damping. This discussion is about resonances, not amplifiers. I wasn’t suggesting a rock solid box wasn’t good, but that your idea of an ideal box isn’t rock solid. Bracing is an integral part of designing a good enclosure. The golden ratio is far from golden and again another rule of thumb that gives people the wrong information. Sure if you are limited to an empty box with no bracing and it has to have 90 corners it is better than a square, but it is FAR from ideal. This discussion wasn’t about the vehicle, but about correct box building techniques. Either way though since the environment is jacked the question then becomes do you want to start with a box with a crappy response and try to fix it in a crappy environment or do you want to start with the most ideal box for the installation and then try to fix the crap the environment creates? Real simple if you ask me, I’ll take the least amount of electronic compensation as possible.

    Good to see you, what's happening?

    7 yr even better, 12 not worth it

    A little low. Probably safe, but you'll hear 10 degrees more

    So offer him $3k. Considering the description I think he might bite. I called and left a message. Good luck!
  9. Goals Space Time Budget Everything else is a little detail.

    Much prefer a hot chick in short jean shorts than cargo shorts.

    Fuck, if you want. I'll do it for you. Hell we could play good cop bad cop and I could email him and offer $2500. Then your $3k will sound better.

  14. Who said anything about 90dB? Why don't you understand that midbass is the challenge and adding sub bass is ultra easy in comparison. No it doesn't. Again you have to address not only the frequency but the damping as well. Adding thickness surely has benefit as you note I even recommended it earlier, but it isn't the end all solution. Sort of like using damper as a blocker. The golden ratio doesn't guarantee squat and is another rule of thumb that is generically not so useful. You also have to do a lot more than not make your box a cube. Symmetry is your enemy. The vehicles "effect" is independent of the box. The only thing you aren't confused by in this post is the long wavelength comment, but inconveniently for you that counteracts your whole accurate reproduction post from before.

    I literally loled Its true though. I've been there

    LOL jean shorts and Z4/Panamera

    I've found that somewhere in the 225F range until the middle of the brisket reaches 190F works pretty well in the oven Same temps I use on the smoker. Expect the plateau to last at least 10 hours meaning you will have it in there for between 14-24hrs depending on luck.

    Can you cold smoke it first for a bit in anything?
  20. No extra force no extra speed. Perhaps it didn't slow much. As for the damage, my buddy was driving his mom's grandprix in 1992 (was a 1991) and hit a curb at a 45 degree angle and did similar damage. We were going much closer to 60mph though.
  21. ///M5 replied to mrray13's topic in Off Topic
    That is because MO is in slow time

    Very true, I'd own an '06 M5 in a heartbeat.. But I can't remember which year had bad problems.. i think it was the '06's can't recall though... large trunk + Fast = <3 The SMG had a few issues if its an early 06
  23. And stiffen up the baffle. Shame to spend that much on gear and not put them in right.
  24. ///M5 replied to mrray13's topic in Off Topic
    My M5 was golden and my Chevy a classic GM turd. Parts are WAY cheaper for the old bm'ers than the new though
