Thanks for the look. Appreciate it. Was a fun show, full of great great people. Funs where had.

10% weight reduction = 7% fuel savings. Government mandate by 2025 that the fleet average of ANY manufacturer selling in the US averages 54.5mpg. You are starting to see some unreliable nasty shit put into cars to get there. Poop loads of lightweighting activities going on. My labs are busy!

Turns out it was a quick fix, all the bolts weren't even finger tight. Didn't have to remove the box to fix it!

If something like that gave real world fuel economy increases, the auto manufactures would be using it. Easiest way I know to get better economy is take all the extra pounds of stuff out of your car. http://www.popularmechanics.com/cars/a3983/4310717/

my last metering with the original Icons was 143.6db @ 10hz...... WITH FOUR 10"........ on a Crown A3000gti that set up was so flat the output only varied 3db from 10hz to 35hz.... the flattest response I have EVER seen with ported subs still KICKING myself in the ass for letting them go the only thing I would have changed on them would have been the surround... I was ripping them off the cone I would have went with a higher rolling surround and called it a day.... awesome woofer

Jeep trip this weekend:

:[ all good but heres a cool video, at the very last 30 seconds he figures it out lol

I would be happy with it, if thats what your asking. With the transfer function of the car you should be right on point, and the sub should blend well with the mids. Youre gaining 6db output in the sweet spot, WITHOUT needing any additional power. Whats not to like about that?

You could shift the port tuning a few hz and see what happens to the peak. Maybe give 30hz and 35hz a try. Beyond that, I honestly think your graph looks pretty good. One of the goals with a ported enclosure is to gain output in the intended bandwidth, which your design is clearly doing. If you want a smooth response, perhaps model sealed.
