Better image link... still wrapping my head around how best to post these things!

Made the most of my afternoon... Mocked up a baffle to get an idea for size, proportions & appearance. I really thought the speaker was smaller than this! Glad I got it out of the box for a "test run", as my original idea wouldn't have worked quite as I'd visualized - It's close enough and the width was restricted.

I still plan on putting LED's in and I haven't figured out the bracing just yet. Slowly but surely.
If anyone notices any glaring mistakes with the drawing please please shout!

Looks like that will work just fine. Proportions are good, very old school hifi. 8L is plenty of bracing, dampening the rear panel will be your main need. Wadding can be added to taste, a dense grade of Dacron would be a good place to start.

I'm not sure why you've offset the horn. The left and right off-axis frequency responses will be different. That's not necessarily a deal breaker, but unless you have a good reason for not doing so, I'd centralise the horn.

I've started the build... In the end, I did decide to centralise the horn. Mostly because it looked like it would sit better visually and it was easier to work out the dimensions. Didn't realise there would be any effect, thanks for sharing! Glad I went down that route. I'll post pictures as and when I get a moment.

In other thoughts - what do people suggest for filling screw caps/holes if one intends to stain or varnish (most likely a darker varnish) the box. If memory serves me well, general purpose Polyfiler won't hold the stain and I'll have a bunch of white dots all over the place! I've read that bee's wax or a similar specialist product could work. Honestly, I'd rather find a home-brew solution (if there's one out there?) as I suspect I may have trouble colour matching, especially now that I can't get into a hardware store for myself - click and collect only at most stores!

Enjoying the build and happy with the progress so far. Only remaining panel to glue and screw is the back and the accompanying braces. I have a bunch of fittings and wadding on order from Blue Aran, so I'll be able to pick the project up again after work next week. 

Lots more to do, but no rush and plenty of (not too steep) learning curves!

As promised, here's some pics of the build:

My stack of plans and thoughts:


Early on in the construction stages. Glue, then screw all round



One of the joints. All the panels were cut with a circular saw. Learnt a few tricks during/after that will be handy next time!



A bit further along the construction. Adding the bracing here. All the joints were given 24-36ish hours of time to cure. Learnt the hard way with one side... Slow down and give each section time!!



Bonus assistant pic



Bracing in and glued up. Feeling sturdy! Definitely removing some of that resonance in the wood



Further along again. No finishing yet, still construction - back panel still to add here.



Back panel getting the glue treatment. I'd be lost without these clamps! By this stage, it was clear that there was some twisting or non-squareness to some of the panels. Nothing was off by too much, but there was an evening of sanding to get it to sit flush, before I could commit to the glue. Worth the effort! You can see the cabling plate I've made up too - only direct wiring for now. Soldering iron's tip bit the bullet half way through unfortunately.



Closer look at the Speakon plate



That's all for now folks! Got a couple more uploading, but having trouble with the image path.
Any suggestions, advice, criticism or questions welcome!

If any of you are on Instagram, I go by the same username as I am on SP. Feel free to follow me, I've been posting updates of the build on there.
Have a great day all!

Here's the cabinet with some finishing. I'm rounding the edges (very carefully) with sandpaper as I don't have a router. Hard, but not impossible! Still need to add a bead of sealant to the back panel (inside) and take apart an old cushion for sound wadding! Attempted to order some proper gear, but everyone's outta stock right now.


Here's a shot of the box, sat atop the bass cabinet. Wasn't too sure if I'd end up with a black finish at the start - so much time and effort's gone into the woodwork, it seems criminal to cover it up now. Couldn't resist seeing how she looked, in place, even if unfinished. Happy with the results so far. Still plenty more to do! I have all of the fixings ready to install and the "prep for stain/varnish" process has begun. You'll notice on the previous pic that I have the wrong colour filler. It's a little too light against the ply. Decided against any more unnecessary trips to B&Q and I'm now calling them a feature!


Enjoy!

Cheers Jammin'! Nice to have the tools out and a project on the way! Long time in the making, but will be worth the wait.
