My Rythmik Audio sub

After many hours of designing, machining & assembly.........

Yes, I did make two for my system. How does it sound? AWESOME!!! These subs are first rate IMO. This is 1/2" thick 6061 aluminum.

Nice!

Wanna make two more?

are you guys serious?

Nice industrial design - if those panels began life as thick 6061, you DID do one heck of a lot of machining!

Congratulations on a unique pair of subs.

industrial? really? Hmm. I'm in the race car industry....this is how most bulkeads are done. but ok. Yes, they are 6061-T6.

Nice industrial design is a complement. This is not saying it looks "Industrial"

ahh! That makes me

Thanks for the kind words...

Yea, those look really good, and very creative! Nice job!

Nice job. I love the aluminum but being one that buys a lot of aluminum, I can only imagine what these would cost to build. Not to mention the machine time and shipping cost.

Do you have your own CNC / milling or do you work for someone that allows you use of it?

I have access to CNC equip. I built them for myself as I have been wanting to do this for awhile. I finally did it!!! I certainly could build for others but doubt they would want to pay for it....

You're welcome. In the world of product design, we speak of ID (some call it IDentity), or the industrial design of a product, which is the appearance/cosmetics, not necessarily what's under the skin. We have our Italian source do some ID for us, as it's important in getting a look that is appealing, ergonomic and therefore helps sell a product. ID and packaging mean a lot (sometimes too much to us product performance folks).

Anyway, back to the important stuff: how did you attach the panels together and what did you line the interiors with?

I used this http://www.soundprooffoam.com/quiet-batt-insulation.html and this http://www.parts-express.com/pe/showdetl.cfm?Partnumber=260-330

As for how the panels are attached they are bolted and glued with a special adhesive. I will post a picture on the bolting.

Here are a couple more pics. The first one is the model. The second is showing how the cabinet is assembled. The adhesive is what really holds it together, the bolts just clamp it together to give the adhesive time to cure.

you can see where the bolts are in this picture...the little light blue dots are the bolts.

The lines that you see in the "pockets" is the tool path. I was going to polish them out before hard coat anodize but decided to leave them as I thought they would add something. It looks REALLY cool in person.

Wow

Awesome job!!

That turned out great!

jtw,
Would you care to share the name of the adhesive you used to bond aluminum? I want to build some aluminum speaker cabinets, but I don't want to expose my eyes to welding. Been thinking somebody must make a good glue for aluminum. I bet it's not cheap though?
Thanks
Rich

richidoo-

This should help you http://www.lord.com/Home/ProductsServices/Adhesives/LORDEngineeredAdhesives/AcrylicAdhesives/tabid/3965/Default.aspx

Keep in mind that welding would be great if done properly...the hardest part of that IMO will be keeping the panels from distorting. It can be done but patience will be key. Also, what type of finish will you do? Post welding if you want a smooth edge you will need to mill/grind the weld, therefore creating marks. Just another step to polish them out. I think that the adhesive/bolt way is stil the best way. I was going to build this in segments but decided against that. I would create "slices" which were about 1" thick and they would bolt/glue together and you would never see any of the hardware. Again, the cost/time involved was going to be MUCH higher then what doing this cost. Happy to help if I can...

Thanks for all nice comments. It does feel good to know that someone else can appreciate it. Too bad you weren't closer to hear them...

so what would it cost to buy a box like this from you?

umm. more then you probably would think it's worth....

just because of the time/material cost.
