Sealed Box Tricks

Make sure that box is like a rock.

The smallest panel flex will hurt you.

Ducttape over the woofer flange.

hey ray ive been spraying the inside of my box with *** spectrum (after adding extra silicone on any "holes" there are) and just had a thought. should i throw some fiberglass cloth in the mix? by that i mean get the surface wet with some spectrum lay the cloth down let it dry for a bit of adhesion and continue spraying? would this do anything without resin? only reason i wouldnt use the resin is i dont think the spectrum would stick to the resin

Use slabs of wood to temporarily decrease the volume inside your boxes. Should help reduce excursion a little and maybe help your score.

Would polly-fill slow down the cone movement to help till you recone???

Poly-fill makes the box seem larger, would probably result in more excursion

X2 don't do that unless you want to go lower or play flatter and you can use to much poly fill and lose output and cause super excusion. Can you say bye-bye spider.

the spectrum instead of resin idea wont do squat.

use resin with the cloth, then give it a good rough sand with like 60 grit then add spectrum, it wont come off.

[Ray]

60 grit?

That shits for pussies.

36grit all day baby.

But yeah gotta resin it man.

And i would try to make the box smaller.

If you can already do a 148+ out of the sealed box it's probably not the box that needs any work. You need to test different things in the car. Try holding certain pannels when you burp the vehicle, try different seat positions, flip the visors down, have someone sit in the middle of the windshield, try bracing the trunk of the car, add some deadener to help seal off some cavities in the car to bring up the car's note. There are so many little things that can add up to a db or even more. I'd be willing to bet with a good day of testing you can squeeze out a db in your car. Also like you said try sealing the box off from the trunk. If you fire everything foward and build a shell type seal around the box it will work like a bandpass and still allow you to keep your sq. It may work so well you will have your 150 out of it.
