Birch vs 3/4 MDF SPL box

[xSPLoder 10+ year member]

I've heard both good and bad things for each. Any professional suggestions or recommendations? I already have the wood for each in my garage so I want to keep it between those 2. The box will be used for music and burbing

I've been told that birch is stronger, lighter and reduces box rise

birch, much nicer to work with than mdf

mdf is used to make boxes for a reason. birch is a good second option though. its stronger lighter but resonates at a higher freq.

I always stick with mdf... if you need more strength add bracing and glass resin. and really I would not advise using a burp box for music... unless you plan on changing the ports which I have seen many times.

which is what you want for a burp enclosure.

FYI, it's also going to be slot ported, no aero's

then how are you going to use it for music as well?? removeable slot ports are a lot of work. and I highly doubt that the enclosure will be big enough for a daily setup because I hope you will be making it small enough to up the mechanical power handling of the sub and to keep box rise down.

not daily music, in the class I compete in this year I have to do 2x 30 sec runs of music. Next season i'm moving up to another class that does burps or sweeps

regardless, the difference in the rez frequency of the material of the enclosure is mainly deadened by bracing if properly built,

and makes very little real difference.

not to mention that I am going to double layer the box

there is such a thing as a burp box that is only a burp box, not everyone needs to play music...

you will be much happier with birch, its massively easier to work with and will be much lighter when finished.

Awesome, thanks for the advice. I think birch is prolly the all around smarter option.

i used birch once and decided i would never mess with the royal pain in the *** that mdf is.

I know 1 for sure plus with birch over mdf, it cuts way better and less mess than mdf LOL
