Default Designing custom speaker grills - help me choose a design?

Ive got some Dayton RS-180's in need of grills, and nowhere to buy them, but hey this is DIY afterall...

I've got a place I can get metal laser cut from cad files. The price will probably be about 20-30$ for the pair out of 1/8th inch mild steel.

So... I'm a bit stuck on the designs. I want something clean and simple, but very sturdy. They will be for kick panels... and they might get... kicked.

So here is 4 i came up with so far. Any preferences? Any SQ considerations with these?

And while i'm at it... let me know if you need any, maybe i can get a better price if i get a handful burned!



Thanks, Brandon

I like #1 the best, BUT is the RS-180 going to be your midbass only or midrange also? If midrange, I'd try to just keep the six spokes without the two rings (like #4 without the curved design. That way there's less chance of diffraction.

Midrange also... playing up to 2000.

I get a little worried about sturdiness on something like that... but Ill give that a try! Thanks.

4 is the only one that doesn't look like a shower drain

Not knocking your designs, it's just the first thing that popped into my head.

Not really any sort of designer actually. just a guy with a computer and Inventor...

And your absolutely right. They all look like Shower drains except for 4. I hate them all now. thanks a lot... lol

Sorry dude Your work was great. I like the 6 spoke design. You might want to look up rims on tire rack and just copy a design you like.

I'd like to see what you finally decide on.

On your second run I like #1 & #3. At this point I guess it depends on what vehicle you drive & what kind of theme (if any) does the rest of it follow? Do you have aftermarket wheels on your ride?

Oh, & cool designs by the way. What kind of stuff do you invent?

Good idea! These are just a few I threw together in some 5 minute time chunks I squeezed in between real work. Maybe I'll spend a bit more time coming up with something cooler.

Well, its a 98 Audi a4. Stock everything. Mediocre interior with tan old leather, wood grain, and an awkward color of blue leather for everything else.

So... no theme. The theme is "please dont kick in my spendy speakers". Lol

Oh, and I do all the mechanical design, web design, and graphic design for a small forklift attachments company. Jack of all trades, master of none.

As far as diffraction...

Quote:
A slit which is wider than a wavelength produces interference effects in the space downstream of the slit.
http://en.wikipedia.org/wiki/Diffraction

This is speaking of diffraction through a single slit, but IIRC the principle is the same for circular apertures or multiple slits.

Wavelength
of 3khz sound is about 4.5", 2khz is more like 6.7"

Thing is, a smaller slit causes more diffraction (i.e. the sound waves spread out more) so .

Can someone double check this?

This one seems to be the best for speakers. I agree with the others when trying to watch out for diffraction. Simple may not be as edgy but definitely better for sound, but that's just my $.02

Default Re: Designing custom speaker grills - help me choose a design?

Well, got the quote back from the metal place. If I get them out of 1/8" stainless steel, theyll be 13$ a piece...

Thats with the "freinds and family" discount. If i got them out of regular steel they'd be cheaper... but im starting to think that the stainless might look better and be worth a few extra bucks.

I think i can do 13$ a piece...

I decided that 6 spoke design didnt have quite enough metal for me... so i tried a 12 spoke one, and a couple other randoms.

Im sick of messing with this, so any input on these few would be appreciated then ill go ahead and order a pair up:

Nope... not unless I ordered like 10 pairs.

I'd give em to you for the price I pay plus shipping if your serious.

I was thinking about ordering tomorrow, so let me know!

Also, if you've got a better idea for a design, let me know. I can draw it up and post a pic.

Out of your newest designs (7-9) I like #7 the best by far. I prefer simplicity.

I was secretly hoping you'd get #8 .. it kind of looks like a BBS RS.

Although, a bar style grille would have looked pretty cool IMO.

I considered doing bar style, but I'm not a fan of the style you pictured, and better ones cost more money, and don't offer as good of protection as these will, and these give me the option to stretch some grille cloth over if I want.

And what's a bbs-rs?

Your final design is very similar to what I made for a pair over the summer.

Great price you got them done for however! The material (aluminium) alone cost me about 5x that.
