What is the best method to reduce airspace in a custom box that holds two 12" JL Audio 12w6v2's? I am trying to achieve a tighter sound, but right now it is a bit boomy.
I have loaded the inside of the box full of half-inch MDF pieces, neatly placed inside. However, I do not want to add that much weight to the car already, any suggestions?
Possibly some kind of expanding foam to reduce airspace??
Thanks in advance
Alex, remove all the pieces of mdf from the inside of the box. Next get some packing peanuts. Find a large container like a bucket of some type and fill it with 28.32 Liters of water. Mark a line on the bucket where the top of the water is. Empty the bucket. What you have now is a bucket of known volume. 28.32 L of water = 1 cubic foot of airspace. Fill the bucket as many times as needed and empty into the box to calculate the box internal volume.
To take up space inside of your box and to keep things light, try the following. Now that you know how much volume you have and how much you need to take away, take some styrofoam insulation and cut it into pieces to take up space inside of the box. Once you have the pieces cut and stacked into whatever shape you are going to make them, use duct tape and seal the styrofoam inside. This if wrapped properly should make it airtight and nice and light. Attach to the box by hot glue, spray glue, resin etc. to ensure it does not rattle around.
