    thanks, i'll do some googling but if you have some links on hands please let me know. thanks!

    i am looking at the Delite 12" and SR versions. those look like they were built in a sealed 1.6cf cab?

    3) No, most folks use passive crossovers.

    i have a few questions, hoping for anwwers

    1) what are the dimension for e-waves? do they varied by versions (e.g deluxe, standard, sr, etc.)?

    2) are the cabs ported, sealed? doesn't matter?

    3) are all e-wave crossovers active?

    thanks!

    Re: Flex Your PCD Mettle:

    Has anyone tried the new MCM cast frame professional woofers in an econowave? I bought a pair of the 8" (http://www.mcmelectronics.com/product/55-2960) during one of their daily deals for $11 each (normally only $20.49) about a month ago. Build quality is excellent for the price. I mounted them in a 0.5 cu ft sealed box and ran them full range with a 1" dome taking over the highs with a single capacitor and padding resistor in line. Considering the circumstances, they sounded great - much, much better than I expected. The first thing that came to mind is that these could be the bottom of an excellent low cost econowave variation. The larger woofers in this line are still very inexpensive ($34 for the 12") and I assume exhibit similar build quality and performance. Has anyone tried these in this application?

    Thanks stgdz for pointing that out.

    Thanks PE for gettin' it done.
    Too bad the 3012LF are now $325 each , that's more than double what they were a couple of months ago.

    Yeh, I can't wait until they give me the final pricing. When I asked them in an email how much the 2 sizes would be, they said $65. But they prototyped the 10" and 15". So maybe that's an average price. I should know very soon.

    It's pretty neat knowing the these incredible waveguides were designed by the smartest of the DIY guys. BWaslo said they were the best he'd ever tested and that's really saying something!

    If we can keep the price down, it would really be the icing on the cake. They tested great and they look great too.

    About a month or so ago the company gave a higher amount, but said they'd have to go over a few things on the rear mounting plate and hoped for a lower price.

    I can get it done for a decent amount cheaper, but the price of the mold is 10's of thousands of dollars. If I thought the demand would justify 1000's of parts, I'd chance it. But I just don't know.

    I'm still working on other ideas and hoping to get the price lower.

    I think it's very good, maybe too good. I bet Earl would agree with me on this one :D

    I've been back and forth with the company and there will also be a 1 piece baffle with the SEOS and obviously the cutout for the woofer.

    They will look really nice!!

    Is it quite as accessible as the bargain bin, ABS-plastic-JBL-knockoff? No, but it also seems you have a superior product in terms of performance. I doubt that I'm alone in saying that at $65, the price is low enough to move a lot of units to the DIY community. I'd worry about lowering it further (ie, buying expensive tooling) once you get a feel for how much demand is out there. Demand-side economics: it works, especially for the DIY community.

    Erich, you're a total rockstar for going after this, thanks. I'll be in line to buy once they become available...

    Cheers,
    Sam

    Thanks. Keep in mind, I'm just passing along the info they told me. If the other company does there's in fiberglass, it will be gel coated, or they might as well do their heated urethane method. They will be as accessible as any other product when I get done with all this. That was my initial promise, and I'll be keeping that.

    As it stands, Autotech's are ready to order and look great. They added a lot more colors to the standard price and the Group Buy is going right now. There are currently about 40 random horns/waveguides already ordered, so if you want something from them that will ship on this next pallet, don't wait too long. :D

    Re: Flex Your PCD Mettle:

    Once you have one, you have all you need for the next mold. It can't cost 10s of thousands to cast a negative of the waveguide, which could be used to make more of them. I mean, can't you just use expanding foam and a release agent to create a negative that could then be filled with epoxy resin?
    It depends on demand, that's the problem. A few hundred, yes, a cheaper mold can be made. No expanding foam though. Silicone would be the best for that, but has to be the right strength. Epoxy resin wouldn't be the best way to go for these, but there are other resins. A lot of that stuff is brittle, and not every part works out. Drop one, it cracks easily. Plus, look at the mounting plate on the back. That's not an easy shape to work around with the huge overhangs.

    Next up would be an aluminum mold for heated urethane. Cost is anywhere from $5k - $10k. $5k is for one part made each time, $10k is for a mold that makes 2 parts made each time. 2 parts made each time is a little cheaper per piece, but the mold costs more.

    This would make some sense if you were going to make 1000 parts or so. Plus the mold would pretty much last forever.


    Then we step up to injection molding to make 1000's. An injection mold is $40,000 in the US. Actually, I got one estimate that came in at $52k. The parts are obviously much cheaper to make then.....as long as you buy the mold. It can be done for cheaper in China, probably half that. But it's not easy finding a company you can trust to send $25k before you get the product. :rolleyes:

    I met a forum member that lives in China and he's been looking. But it's still a huge risk to take. Keep in mind, I run a landscape business and I'm just doing this to help out as much as I can. However sending $25k+ to an unknown in China isn't the easiest pill to swallow just to get the lowest possible price. And that's IF 1000's need to be made.

    If you think of an idea, let me know, but I may have already looked into it. That also includes having local audio companies help out. ;)

    But as promised, I will get it done one way or the other. I've been working with the local prototyper for many months. It can be done right now in the US for close to the price I listed. I just thought the price was a bit high for the average DIY guy. They can also be ordered through Autotech as well. They said they'll continue making it as needed.



    As promised though, I will get this done. I was just trying to get the end price as low as possible.
