Fiberglassing the inside of a subwoofer box?

[Matt A 10+ year member]

Hello,

I am planning to fiberglass resin the inside of my 4 12s box... my current box is now 7.25 cubes internal before woofer and aero port displacement... I am going to use 1 gallon of resin ( which will bring airspace down as well as increase strength and airflow) and I was wondering if doing this would lead to definite gains on the meter with resin alone? I have never done this before so thats why I ask... my system is listed in the sig ( box listed below is not current one at the moment)... Thank you

it makes it denser and smooths airflow... also pretty much guarantees no leaks...( all beneficial )

thin the resin 50/50 with acetone before adding hardener... it make it absorb and spread smoother...

what would be the typical increase on the meter with resin? and is a whole gallon needed?

there really is no "typical" gain on a meter with resin... some people gain, some people lose
