1" MDF stacked or should I say layered instead of the traditional way of cutting 6 pieces? I wanted to make a template and cut multiple pieces and then glue them all together to make the cabs.
Would this be too much to do for a beginner DIY speaker builder? I know it will take time but just hope I'm not getting in way over my head on this. The cabs are going to be around 32H x 18W x 15D. these will be more narrow in the rear.
Any info or comments are welcomed! :)

I still firmly believe that in order to fix ones eyes and hearts, One should at least reach 5 foot 6 or so with cabinet design. Five drivers on each side or as many as ten wouldn't hurt the triplex of motor combination to achieve acoustic perfection.

for the replies and info.
The more I looked into this the more I was convinced that this is maybe out of my league for now and would cost a lot to gather up proper power tools to do the this job.
I will most likely go the traditional route and just take some of the tips for the internal diffraction and bracing.
I will post back once I start the cabs here a week or two. Hopefully I can post some pics to show my progress.
Thanks everyone!
If you're happy with a box shape, then follow the suggestions of the others.
If you want to layer and get a nice smooth teardrop shape (the only reason that would be worth layering), here's how you'd do it by hand:
(tips: don't do this inside and wear a good respirator)
• Cut templates for the top/bottom piece and then an interior piece. I usually design in Illustrator, print and use the printouts as templates. These templates need to be perfect. You'll want thick walls (one of the benefits of laminating them together and you're paying for it anyway).
• Drill two aligning holes that a dowel can fit through in the interior template. This hole will help align the stack when gluing. Gluing without a dowel is a wretched exercise.
• Rough cut the outline of your template on additional pieces of wood/mdf with a jigsaw and/or bandsaw
• Take your templates and make one copy each by clamping the rough cut wood/mdf to the template and trim off the excess with a router with a trim bit.
• Now you're ready to repeat the exercise, but glue each layer of the rough cut mdf using the dowel holes/dowels for alignment. Do one layer at a time.
• At layer three, curse yourself for taking this method.
• Calculate how long it took you do to three layers, and then project 60 more layers in hours (A). Calculate your yearly free time in hours (B). Calculate your life expectancy in years (C). If A > B X C, abandon project.
• Call up someone with a CNC router and pay whatever he asks.
I tried this for a front horn (search forum for blochorn). Unless you have a very well equipped space, I'd say the labour, waste and dust exposure is too much for a large cabinet. If you simply want to scatter reflections inside the cab, just cover the interior with scraps and offcuts. If it's the visual effect you seek, I'd consider layering up scrap timber, such as pallet boards or demolition floor boards. Real timber or ply looks great layered up, even cheap or scrap stuff.
Many speaker cabinets have been built this way. It will take a lot of time, is somewhat inefficient of material useage, but can have excellent results if done well.
If you are willing to accept the challenge, go for it!
Google Translam speaker cabinets for more info.
Here is a link to a rather ambitious project.

Might want to do the angled thing internally and keep the exterior square.
