Tweeter Spheres - pics and examples

[Bettr n' Revrse]

I'm doing this I just am not sure I have the tools... Gunna use seas prestige soft domes I think...

I want a pair. Looks like I need to buy more tools.

I like that swivel idea. I had already bought the threaded nipples to use for mine.
I was going to try the PVC end cap idea though Cheap, adjustable, easily replaceable tweeter pods - DIYMA.com - Scientific Car Audio - Truth in Sound Quality.

Anyone know if there's a difference between the wood spheres and the PVC end caps as far as performance? or is it pretty much the same principle?

[keep_hope_alive]

i have PVC caps also.

yes, the same principle.

the idea is to eliminate any hard edges around the tweeter. using a cylinder (pvc cap) is very similar to a sphere.

The Forstner bits are the way to go - but mine have a smaller guide spike $25 for the small set, $50 for the set i have. the larger bit is $25 by itself. You could just buy the forstner bit that is the size of your tweeter. The Irwin version has a better guide spike. The hole in the wooden sphere is larger than the spike, so the forstner bit wobbles a bit at first. If you have a paddle bit you can get a similar result. If you have a hole saw, you will need to fill the hole created at the back. you will need a vice to hold the sphere steady, and i have found double-sided foam tape works well to prevent marking and hold it in place.

I have access to a drill press - and will get it in my garage soon.

The wood is more rigid as well.

i feel the spheres are better, but a cylinder is capable of being as good if not better based on Dickason's measurements. but note he is discussing mounting on the side - not the top.

I actually like the look of the wood spheres better, but like the ease of the PVC caps. Still deciding which one I'm gonna do.

If I were to do the cylindrical PVC cap, would it be better to have the tweeter flush with the opening or recessed in a bit? I guess if the idea is to avoid hard surfaces around the tweet, they should be flush, huh?

The best ones I've seen have some mechanism to swivel them once mounted to really dial them in once mounted.

flush is best. the swivel air tool linked in the previous page is a great idea. i will employ that soon.

I finally got these done today and I was NOT expecting the huge difference these things made. My tweeters were initially on the dash facing the respective headrest. Now they are about mid way up my pillars, same aiming and it made a world of difference. My entire stage seemed to just open up. Also, even though the tweeters are actually closer to me than they were before, the vocalist seems to be right about at my windshield wipers instead of right at the tip of my dash. Instruments/musicians that were about halfway between center and far left or right now have more definite placement and my high frequencies seem a lot more airy with the tweeters being pretty difficult to locate by ear. Overall, I am very impressed and this is using the PVC end caps. I will be changing to wooden spheres some time next week.

Just thought I'd share my experience

Thats right after they were sprayed. I should have let them sit a little longer as some of the paint came off when I went to install them. Not a huge deal since I'm going with the wooden spheres soon.


This is before I put the tweeter in. I didn't take any shots after the tweeter was in or of the other side. I can tomorrow when its brighter outside though if need be.


I also didnt intend for them to stick out so far but it was what I had and I dont think it looks bad, so I left it. I might switch up to shorter "threaded nipples" later though

Glad you like the improvement. Menards had the swivel air tool fitting for $3. I got some to try.

Is it exactly the same? If so, could you link them to me so I could order them from Menards? I wish we had a store over here
Also, I'm currently still using a standard passive component set. Would you think the pods even worth the effort at this point? Or should I just wait till I switch to an active set-up?

Any front stage, active or passive can benefit from spheres. The setup he did in the tC used spheres and that set was passive. Diffraction doesnt care about active or passive lol
