djk Posted May 21, 2016 Share Posted May 21, 2016 I'll ask a friend in Baton Rouge if his son will do it, he would need to borrow a horn to scan. 2 Quote Link to comment Share on other sites More sharing options...
quadrokot Posted August 30, 2016 Share Posted August 30, 2016 Friends, use Faital pro 200 together with 402 horn. High frequency audible only on the horn axis. Therefore, using a high-frequency driver. Quote Link to comment Share on other sites More sharing options...

I'm still looking for K402 details. I couldn't buy a pair from US after a year of communication with Panacea Engineering so I just gave it up. Recently I found a good way to cut plywood or MDF or any other material with a CNC milliong machine so build horns. Now I can build K402 with any material needed. I think a BB plywood K402 will look fantastic. I'm talking about 0.02mm of accuracy on the milling machine. if there is anyone who has K402 at hand and can take it to a 3D scanning office, I will pay for the scanning. I really want to hear how it sounds on top of a Jamboree 1 Quote Link to comment Share on other sites More sharing options...

They usually carve piston engines with it, but I'm sure it would be a cakewalk to do a huge block of mahogany, who knows. That is something I would NOT share and there would only be one pair in the world like that, if, if, if. if you can provide me K402 details I may be able to build a pair for you if you can find a way for shipping Quote Link to comment Share on other sites More sharing options...

oohms Posted June 22, 2017 Share Posted June 22, 2017 You can get it looking pretty close by using established measurements with some guesswork, tractrix spreadsheets and CAD 2 Quote Link to comment Share on other sites More sharing options...
NBPK402 Posted July 5, 2017 Share Posted July 5, 2017 I also would like to be able to make a pair that are just like the 402...as importing them to Mexico appears to be pretty expensive with import duties, plus VAT which is all calculated by including shipping costs. I would like to do this as I believe a wooden one or fiberglass one will be better than the one I made is.

Marvel Posted July 10, 2017 Share Posted July 10, 2017 You can use a Microsoft Kinect and free software to make pretty accurate 3D scans. Even if you have to edit the data sets, that is possible. Bruce Quote Link to comment Share on other sites More sharing options...

I agree with this. You should protect your intellectual property. As a photographer, it would be impossible for me to say how much I've been ripped off by clients who violate copyright law because of the ease of scanning my photographs. If I ever make a pair out of wood, it would be a slight performance compromise for the sake of aesthetics and for personal use only. Meanwhile, I'm on my second pair of K-402's with TADs. Rigma comes to mind here. I have been to his house, and there's a man who "did it right," in terms of cloning for personal use and AESTHETICS. But other than a pair of pretty Jubilee bass bind clones, he has more factory built Klipsch speakers than anyone I"ve ever met. Much like I buy original music so the original artist get his/her cut, ever though digital copies are easy, it just isn't right to steal intellectual property and sell it.

Marvel Posted July 14, 2017 Share Posted July 14, 2017 Is that considered a positive or negative? I've looked at this before, and it's not considered a very high rez dsvice, but some researchers used one on a huge T-rex skull with a .5 mm resolution. I would consider that pretty good.

That's a pretty tough tolerance to attain on the finished part, even if the measurement device has that level of accuracy. Measurement accuracy is only half the solution...at best. Fabrication is another issue. Chris Quote Link to comment Share on other sites More sharing options...
