Does anyone happen to have info on the 4070 cups? What kind of wood it uses, other materials if any, dimensions (doesn't have to be exact), where the bass port is, how angled the drivers are, etc.

I have no idea what wood was used as I never opened my set but they use the standard Lambda baffle (i.e. flat) and the port is in the baffle. There is a cut out running almost the full length of the baffle from top to bottom on each side of the driver. Here are the only pics I have:

Thanks for the pics. Is there anything you can tell me about dimensions? It looks like the cup is curved on the inside to minimize bad reflections and also angled, which agrees with the stock pics on the internet. Also, do the cups have anything other than fiberglass? I can't tell in the first pic since it's a bit blurry.

While I'm at it, what happens to the sound of the Lambda Pro if I remove the stock damping like Kai did?

Also, where exactly is the port? I'm a bit daft, I need it to be pointed out to me.

Look at a picture of the stock phones and you can see the cup design...

They are the same size as a Lambda but just deeper so the flat part of the housing is about the same size as a Lambda

When you remove the damping you expose some of the things they were trying to hide in the first place, namely the upper midrange etch and some bass issues.

Look at the last picture of the baffle and notice that the long sides have a notch cut into them. That's the port.

Thanks, that helps a lot. Now to figure out how to make wood that thin without breaking it...

Buy a CNC machine? I'd start off with plastic or fiberglass cups as they are easier to handle and you will have to make a few prototypes.

The whole reason of using wood was so I didn't have to source a CNC machine.

If I take two blocks of wood, how many years will it take to sand in the holes for the cups?

a lot longer than if you were to use a chisel or a knife or a router.

LOL even a spoon would do faster

Cut in half. Commence sanding. See you in 10 years.

Pic post fail.
