Let's Design A 2x12 Cabinet.
#1
Let's go ahead and get one thing out of the way before my long post. I am a carpenter by trade. I've been framing houses, running trim, remodeling, and working in cabinet shops since I was 14. I even spent 7 months in a custom car audio shop building the cabinets for competition systems. I got this! Lol!

So, I have 2, 16ohm ,Celestion V-Series 70W drivers coming. I got them in a trade with another member here, "if he wishes to be known he can speak up."
These speakers have been described as a G12H/ Greenback cross. 

The cab will be meant for future use with a homebrew 2203 build, but for now it will sitting under a Peavey Windsor that is being modded as close to a 2203 as I can get it. So, you get where I'm going with this, right?

The cabinet will be built out of 3/4" solid pine, just like the old stuff. I just have to find pieces wide enough for my needs, and that is why we are here. I need to get a design ready so there is no confusion or guess work later.

My initial idea is 31" x 15.25" x 21.5". That leaves me 29.5" x 13" x 20", after baffle inset.  A grand total of 7670 cubic inches, or 4.439 cubic feet of inside airspace. That's not a bad sized cabinet.

Not sure if I want to front or rear load it yet. If it's front loaded I won't have to make a removable back. I'm just not sure if it makes a sonic difference or not. The interwebs is split about 50/50.

I'm wanting to sand, stain, and Polly for the finish. The only problem with that is, I have no dovetail jig and don't plan on buying one. I'll to 45, glue, and screw all my corners. I was planning on recessing the screws and filling the holes with putty. You'll see them, but oh well.

That's the partial plan for now. Any other ideas or recommendations? I'm wanting to pick up materials tomorrow and get started.
I hear Mexico is nice this time of year.

Ax84 has a great 1x12 grrrr , should just cut a dowel and put wood in it to cover the screws. Too far away to use the brothers dovetail anyway. Getting into Tolex is almost always no fun too. I wonder what the specs on Devins Hovercab are , that thing is oversized and sounds great ?

Flat black spray paint and steel amp corners.  Start here...

Someone should put that in their signature…

I'm wanting the overall design to look like that British companies, just without the tolex, and logo. Is that a port across the bottom of that cab?

I'm kind of wondering if I can get away with a birch ply baffle. From what I can find, my back panel it going to have to be a 2 piece. I can't find anything over 16" wide.

I do like the idea of painting it black. You'd never see my screw holes. I think you can get some stuff in can like Rino Lining. I'm hoping I can find something like that.

Nice dude

Don't most people use birch ply baffles?

I like the idea of the flat black cab too, especially if I was gigging with it.

If it was just going to sit at home though, who knows what I would do... maybe a nice figured walnut veneer over the pine frame or something more exotic... who knows.

Yeah, I'm thinking that 7 ply birch at lowes is going to have to work. It does seem to be common. Now i'm hung up on if a 2 piece back panel will take away from that musical effect of a solid pine cabs flexibility. "I'm just knit picking now, I know."

I'm also curious about that port in Dr. Veg's picture. I've always preferred a sealed cabinet, but it may have it's place with these Marshall style setups. I'd like to know the reason for it.

You can read about porting here.
- https://en.wikipedia.org/wiki/Loudspeaker_enclosure -
I'm a sealed box person myself because they produce a tighter bottom end and overall sound to me.
Up until more recent years I gathered most speakers were designed to operate in air tight enclosures.
None the less porting has existed since the early years of sound.

I've just never used a ported guitar cabinet before. I'm not really sure if that will benefit or hinder what I'm trying to do. I'm in a 18x18 room, and it will probably never leave this room. The main use will be recording, and getting my jollies off when I just want to crank the amp and jam on 70's-80's rock/hard rock. 

It's not like I'd be gigging with it. I gave that shit up a couple years ago. This is for fun.

I've been thinking about doing a build of a 2x12 guitar cab too. I'm not sure if I would go ported or not but my decision is pretty much based around what speakers I would use. I am not a very experienced woodworker but I have some basic skills. So it would be a lot easier for me to build a closed box and just throw in some non neo speakers.

Mine would probably not be very pretty but it would be functional.
