How thick does aluminum need to be for a solid non-flexing baffle for 2 12" subs for infinite baffle? I read that aluminum is 3 times stronger, so could you technically use 1/4"?
You need the modulates of stiffness, not the strength...How thick does aluminum need to be for a solid non-flexing baffle for 2 12" subs for infinite baffle? I read that aluminum is 3 times stronger, so could you technically use 1/4"?
Back to skis...I have 1/4 Aluminum plate myself that I’ve used for various projects and if you made a sandwich with rubber between two 1/4” plates then you would have the ultimate non-resonating baffle. 1/4” thick Aluminum plate by itself is pretty stout.
looks are a big thought with aluminum. I have another idea also, but just did a bathroom remodel a few months ago and used aluminum for a shelf and I really liked how it looks. I would be cutting with a router.
I'm never been good at modeling ported enclosures (on built a couple in my life for others and both turned out really well).Did you model them? I can model them with Bassbox Pro tomorrow if you want. Resonant frequency is low on those.
I have cut and shaped aluminum on a router with wood bits, only up to 1/4" though... Let's just say, it's not for the faint of heart!Jerry, I need to agree with the others.
Make a birch baffle and cover with thinner aluminum trim. Just like most countertops and shelves. You'll save yourself fists full of cash.
If you feel the need to stick with billet aluminum then 1/4" seems a little thin. You may encounter resonances. Go with 3/8th" or better yet 1/2".
Also, how the heck would you cut this with a router? Curious. I wasn't aware a wide variety of metal bits existed. Also, how would you keep the bit lubricated / cool?
