I never used Birch to build a box,I did a little research on the Lowes website review section and there were some not so great reviews about the quality build...sooo my question is where do you guys who use Birch purchase your wood? and what size in thickness do you use generally? lot of questions but how else can I learn?..Box will be housing 2-12 Soundown 12"Zs with an 6"Aero Port. Thanks for input.

never used it im classic, and just stick with the mdf, as long as its sealed and braced right don't see why you would have a problem.

I was talking to Dave the box guy (spltuscon on here) and he told me the wood he's had the best luck with is Arauco Plywood ( Shop 23/32" 4X8 ARAUCO PLYWOOD ACX at Lowes.com (http://www.lowes.com/pd_161485-49114-LBR-161485_4294934117_4294937087?productId=3014767) ). Costs $7 more than MDF, about 20 lbs lighter and stronger. The plywood is advertised as 23/32, so even if it's slightly smaller it will still be around 3/4".

I've never worked with plywood before. This makes me wonder how it would handle roundover bits, say, if I used a 1"-1 1/4 bits to it. I would be afraid that the layers would splinter. Has anyone done this?

birch machines really nice its virtually void free dont use roofing plywood birch is like cabinet grade stuff very high quality

and besides weight and strength over MDF by leaps and bounds it :

1)takes screws .....over and over without stripping
2)makes less dust
3)isnt so damaging to your tools( bits and blades)
4)takes nails and screws to assemble without splitting like mdf
5)dont swell if it gets wet
6)can be stained and the end grain dont **** paint like mdf requiring tons of work to either seal it or coat it until it stops absorbing

birch machines really nice
So does that include taking roundovers to it? I wanna go as big as possible considering the small size of my trunk and squeezing that thing in my trunk hole will be helped with the use of roundovers. Not only that, but it just looks much nicer. I also like the idea of having much less weight in the back.

I get mine at lowes and I will only use baltic birch. Laminated birch is junk. Birch is stronger and lighter then mdf by leaps and bounds. Cost a tad more but why skimp on the most important part of ur substage.

I use baltic birch for pretty much everything. I may try using 1/4" thick for next box due to size constraints, but usually use .75.

Ok, I use titebond II for MDF. Most builds that I have seen made out of birch, the builder used that PL stuff. Would PL glue be better for birch?

I use titebond 3 on my birch boxes and I have never had an issue..

PL or TBII either or. Don't really matter. I prefer the TBII.

use wood glue. Pl400 and the similar are construction adhesives mostly used for gluing plywood down to form floors. It's not made to bond the 2 pieces together to hold when constant pressure is applied.

some home depots have a cabnet grade plywood that is just the same as birch, i use it to build every box for customers and such... its only 24 bucks i even use it on my own boxes.. and this type of wood doesn't hurt our scores any... although onetime we forgot to vaccuum all the saw dust out one time... smelled like a forest fire in that car LMAO!!!!

This is what mine is.. Im very happy with it. And the weight is great for my small car.

How are the Acoustics/sound within the lows verses each other??Id figure the burch would echo,as the MDF would absorb the ecohing sound??Looking to build for 4-xtra heavy 10s in a x-cab Chevy..Was to be using 1in Mdf as always, but you guys have me considering??Does it sound a bit more heavy/or ??Think I used reg Plywood back in the day when I was broke,yet dont remember the reason for the change.Any other input may change my new install.I dont mind the weight,just the Acoustics??Thanks:wallbash:

The biggest difference in a daily system is all in the workability. The difference in sound is negligible in an unprepared cabin. To truly hear a difference you need to put each in a sound booth side by side. With out doing that or similar you will never hear the slight resonance. That only goes for normal people though, audiophiles and sq guys will probably be able to pick up the difference just because of the added experience they have had with listening for those type's of things. I have said it tons of times before but, If you want to hate your car stereo go listen to some properly prepared HT equipment.
