Re: Tricks of the trade?
The only thing I can say that I have found out is lots of port area, a well designed box that doesn't flex, coat all exterrior walls with resin. I have also found out that box size depends on the amount of power you are using. A larger box will make the sub(s) more efficient. But this is only good if your using a minimul amount of power. If your running them at or around the rms value, you may actually want a box around the reccomended size. If you want to put more power than the rms value put them in a smaller box so they can handle it. (This is why you see guys putting 5k to a 12"...it's in a .5cu' box)
I have an sql box for my Brahma. It's 4.5cu' tuned to 38Hz....makes my stomache hurt. Tune your box a little higher, like Gauntlet said. Some where around 36-40ish. I have a few ideas for an all out spl box that I will be competing with next season, but your interested in sql so I'm not geting into detail about it.
