To learn more about box building check this out:

I started using water resistant MDF (its a green/olive color). This stuff is about double the density and weight of regular MDF. I have yet to find another wood product even close to this. It is even more enjoyable to work with than Birch (I have worked plenty with Baltic birch and regular mdf). Because it doesn't absorb moisture, painting it is a pleasure without the need to seal cut edges. In terms of sound and especially bass response, it performs incredibly well.

MDF kills tone.

I’ll stick with plywood. You can deaden it no sweat and it’s tougher to damage and moisture won’t instantly damage you box.

The very BEST Wood for your subwoofer is dessard ironwood!

I'm building Hi-fi speakers out of 1" Baltic Birch...which is actually 18mm. Stuffs expensive for sure. The other main problem is that it comes entirely from Russia, the same Russia that's invading Ukraine right now. So imports have stopped, and prices are way up. It's a beautiful material though.

I dislike mdf its like pressed wood dust. Too many stripped holes ive seen with mdf even when i used screw in threads with glue. I actually prefer plywood as birch is $$$

I BET i'll believe it. i BET you're gonna tell me with your hands and I can leave the volume down

MDF all the way and all day long.

liked the Video just pointing out a little bias. You said that most people talking down on the MDF are actually talking about particle board not MDF. At the same time, for 80% of the video comparing Birch to MDF, you talked about Pine and not Birch. Just Sayin cheers.

i remember the first sheet of mdf that i bought from home depot was $6. back when i was first getting into enclosures, i used plywood, osb and particle board those all could be had readily for $4-5 per sheet. i recently made a sub enclosure from some scrap osb i found in the alley next to a construction job. solid box. cheers

Great video overall. Thank you! Another thing--you taught me a much-needed Baltic Birch thing or three I did not already know.

Cool! Yeah, I definitely like DIY projects. I've never done anything with speaker or sub enclosures, but have been really satisfied with the potential of old reclaimed pine and the finish that can be achieved.

I like the birch simply because of the weight. Sometimes I have to take the box out of my truck and plywood definitely saves the back!

love the channel and content. Its been decades since i built an enclosure; that said,, I live in the south with all of the great humidity.

All good points 👍 Justin keep up the great work

I switched to 1/2" 6 ply Baltic birch from Rockler years ago for my guitar amp/speaker cab projects and have never looked back. Super solid and light weight compared to 3/4" MDF. Plus I can simply stain/poly the cabs and call it a day. There's nothing wrong with MDF - but I would never go with if for anything that has to be moved around or exposed to the elements (like beer). I really appreicated the safety issues you point out! That's one thing a lot of newbies over look when when start on these kind of projects...

Very well put together. Love It!

I sealed my mdf with a white sealer. Just left it white. Worked great

Excellent presentation, thank you !
