DIY 212 speaker cab build...

FastEddie

When I started reading this thread I got twitchy hands. Then I saw power tools and the quality of your work.
I think I shall now give Zilla a call. 
Great work.

Will the baffle remain inclined?

No, the baffle will be fixed to the front once the grill cloth is fitted. I made it like this so I can take it out again easily in the future.

Smart. 
Any thoughts on inclined baffles?

Not really, they look nice but a little more difficult to make, this has caused enough brain ache as it is.

My office is full of 2 x 12 cabinets, definitely my preferred option, Also the best ones are on the diagonal like you have made.

On most of mine I put additional bracing on the baffle from the front to the rear and it did make a noticeable difference at higher volumes, the sound just holds together much better . Might not be an issue with yours depending on how thick your baffle and rear panels are though.

Well done!

Thanks.
There's scope to add more bracing if needed. I've used nice 18mm birch ply b/bb grade all round, so about the most substantial 18mm ply available, plus  it's only going to be used at home so I'd be surprised it cab resonance is an issue, will find out soon enough, can adjust if necessary.

Looking forward to finishing it now.

Here's a few more pics

Used a fence and a stop on my pillar drill to ensure the holes were all in line, worked well enough.





Used T nuts (and Allen bolts) to secure all the back panels to the cab, more work but a better long term solution compared to regular wood screws.



Fitting the grill cloth isn't fun...
Didn't manage to get it 100% straight, but it doesn't look too bad for a first attempt. 









This ended up being more involved and time consuming than I expected. Nevertheless happy with the result. I'm going to apply a finish to the plywood at some point but that can wait.

Cheers.

A good clean result. What’s that on top? A perfect combination in any case.

Nice work mate, you e motivated me to build a custom angled cab that I’ve been meaning to do for a while now

That’s a very nice job - I like the clean natural look of not having vinyl on the cab... I assumed you were going to cover it. And a very neat size, since I know how (not) big the amp is!

Thanks, I could have reduced the height by another 10-15mm other than that I doubt a diagonal 212 could be much smalller.

The grain on the wood is too nice to cover, I'm going to order in some Osmo oil samples and try them on scrap, leaving them for a month or 3 to see how they settle over time before finishing it.
