Tweeter Spheres - pics and examples

I figured it makes sense to have a tweeter sphere thread here as well.

I started making another set last night, worked on them a bit more tonight.

I buy solid wooden spheres ($1.50) - like knobs or post tops, at my local Hobby Lobby. i hollow out a cylinder, (using Forstner bits, hole saws, dremel, etc.), drill a hole for threaded rod, and then... i'm not sure where to go next for a nice finish.

i used double-sided foam tape to hold the sphere in the vice without making marks. works well.

I had to dremel sand the opening a bit larger in order to fit. the Forstner bit was either too small or too large. :(

i haven't decided how best to finish off the mount. there is a gap around the tweeter face due to it's construction. the widest flange is in the middle. so i need something to create a smooth transition. and then the grill - the Vifa doesn't have one. i have one, but it's larger than necessary.

I read the discussion on this concept and do think it's a neat concept. Looks even neater to me, too. Just wish I hadn't cut my doors before this came up lol.

before Forstner bits - a hole saw first

then a paddle bit - we used two to create a ledge

then a dremel to smooth

how do you feel about reflecting off the glass?

Siiiick!! I want. Price for a pair? Lol.

You should see my lame *** attempt with a ball o' yarn and some resin. Lmfao. Strictly experimental and with stuff I had laying around the house. Well, my Mom's house. I ain't got no yarn at my crib.

Here you go...

little dip in the resin to make caramel apples.

aiming the tweeters toward you eliminates dominant windshield reflections.

firing across had reflection issues that resulted in phase interference.

reflections in the scion are off the nearby side window - which extends the soundstage width to beyond the side mirrors. it's cool.

the spheres in pods i have now are ok, but not ideal. course, they are just some random RF tweets i had laying around. they sound good for what they are.

i got about 2 hours of work in the new tweeter spheres so far (first set of pics).

I was just reading through the diffraction thread on DIY on my way to AZ the last week...

I made a set of tweeter spheres using rubber balls. I needed a 1-13/16" hole for my tweeter flush mount cup, and the balls I found at the hardware store in the pet care department are just about perfect. $1.79 for 2. They can be cut by hand with a sharp knife and fine adjustments are done with a sanding drum on a Dremel.

:omg:

This was a huge help man... I've been debating between a flush-mount of the tweeters in the sails or a-pillars... and these spheres. Any experience flush-mounting in the sail panels?

exactly what I plan on doing with my tweeters. I just don't know what size I will be going with yet.

dude how much for 2 of them........if not where do u get the spheres from? holmes depot?

They don't look too hard to make if you got the tools man. Let's give it a shot next week?
