I,m amazed by the use of copper for the melons. You would think something lighter would work out better and add some sensitivity along the way.
But then again, when you have house amps this size who cares!

Regards
David

When I said no uneducated comments, I didn't mean no praise
Thanks for the kind words.

Magnasanti,

Thanks for answering my questions on the other thread. It sounds like you have a good approach - make the metallic base parts that the lamellas attach to before making the lamellas, otherwise you won't be able to test the lamellas. That's great you have made the mold for the lamellas though. The mold is the hard part, as the fun part is actually making the parts from the mold.

Once you said 'samurai' carbon fiber, I immediately though pressurized/heat setting, but you already have a plan to vacuum bag and cure it in the oven. Do you have the compresser and bag equipment? What type of oven are you using to heat set these parts? I have some equipment at work I can use (compresser, bags, all types of ovens, mill, lathe), otherwise most of this work is done in my garage haha. I do not plan on using fiberglass for my cones, but it's cheap and I wanted to see what I was working with before spending more on aerospace grade carbon fiber or pre-pregs (many types of fiber materials her: www.hexcel.com). The only other fiberglass work I've done before this was repairing surfboards.

So you had to purchase a driver specifically for it's voice coil and magnet? Is it the Dayton Audio RS52AN listed in another one of your posts? I'm still on the look for voice coil sources, but it may be cheaper to buy cheap speakers from parts-express.com or wherever.
