Lightweight enclosure

[Gala69 0]

Hi to all, I'm new to the forum and I need info about a new enclosure based on two REaudio sx12 subs, I've thinked about a 4cf tuned to 35hz box 'cause I listen to hipop/rap and r&b kind of music. Can the box be built with mdf light or mdf ultra light material?

You can use baltic birch void-free plywood. That stuff is a lot lighter than MDF. I made my last box out of it. Or you can make it out of fiberglass, but that's a fair bit more work.

Thank you for the reply, is 4cf tuned at 35hz the right box for these subs?

That sounds pretty good.

Ok, there's someone who can help me designing this kind of box? I need to fit it to the trunk of my beemer.

what are the dimensions of the area you have to work with?

i dont know the strength properties of going with mdf light or virtually any other wood that is lighter AND costs nearly the same...

Typically, the lighter the wood is, the more expensive it will be if retaining or even increasing it's strength. Some wood used in boats cost over $200 a sheet and is very light but impractical.

My suggestion is to use bracing in the box just as a precaution for whatever lightweight material you choose to use.

I'll take some measure of the trunk.
