kevinmi Posted December 11, 2009 Share Posted December 11, 2009 These are not complete yet, but I wanted to try out the Selenium D405 2 inch phenolic diaphragm drivers before I went any further to see if I'd like the sound. I did a short comparison with 1- 2 inch horn vs. my K55-V driven tractrix horn. It's not an easy comparison, but what I info I did get is that it plays louder, so I'll have to attenuate it more than the -5 db that I have my 1 inch horns set at. It seems to be more open and a little crisper than the 1 inch, but still retaining the same timbre overall, with a little bit quicker response. Although this driver lists a response of 300hz to 7000hz with a recommended 500hz crossover, I think crossing it over at 400 is a safe bet considering the low amount of wattage it will see in real life. I heard no signs of it breaking up whatsoever. But remember that this driver is only good to 7000hz, so it won't work in a 2 way system. My complete upgrade will include new tractrix tweeter horns also. Stay tuned.. Quote Link to comment Share on other sites More sharing options...

Marvel Posted December 11, 2009 Share Posted December 11, 2009 Kevin -- those look really nice! Are you going to try to match the color of the horns to the Khorn bass bins? Bruce Quote Link to comment Share on other sites More sharing options...
jwc Posted December 11, 2009 Share Posted December 11, 2009 Those look great. Gonna have some great low mids. I would be curious how those perform above 4000Hz off axis. jc Quote Link to comment Share on other sites More sharing options...

kevinmi Posted December 12, 2009 Author Share Posted December 12, 2009 Kevin -- those look really nice! Are you going to try to match the color of the horns to the Khorn bass bins? Bruce My goal is to match them to the bass bins. This one is a little lighter right now, but I'm going to darken it a bit. It's not really that far off, but the finish is too glossy and reflects light too much. The other one I'm making turned out much better, of course!

I would be curious how those perform above 4000Hz off axis. jc I was really suprised how well that horn sounded sitting on top of the K-horn. My plan was to hinge the horn so I could angle it down a tad (the tweeter will be underneath it), but I might not have to. I didn't notice a lot of difference from sitting or standing. My listening room isn't really big enough to worry about off axis sound (18' X 12'). Quote Link to comment Share on other sites More sharing options...

Coytee Posted December 12, 2009 Share Posted December 12, 2009 Comparison of the Selenium 2" driver to the K55-V driver Love the comparison. Horn looks great! Is it destined to be in view, on top of the Khorn or are you considering trying to build it into its own top? (clearly it won't fit in stock form nor shape because of its height) Quote Link to comment Share on other sites More sharing options...
Don Richard Posted December 12, 2009 Share Posted December 12, 2009 Nice! We like big horns. Quote Link to comment Share on other sites More sharing options...
jwc Posted December 12, 2009 Share Posted December 12, 2009 OK. Just worry about that horn being beamy after 4000Hz. Just a consideration to XO a little lower if possible. But if it sounds good the way you have it, right on. Love the big horns... jc Quote Link to comment Share on other sites More sharing options...

Is it destined to be in view, on top of the Khorn or are you considering trying to build it into its own top? (clearly it won't fit in stock form nor shape because of its height) When the project is done, the oak horn will be on top with the black top that I have now. The tweeter will be in the middle, painted black to look like the original riser. Both the tweeter and oak squaker will be nekkid (no grill cloth) The tweeter will be a wooden tractrix horn driven by a Crites (APT50) driver.

Mike Dubay Posted December 13, 2009 Share Posted December 13, 2009 Great job on the oak veener horns! Are you in need of any 1 inch wide iron on oak veener? I have a bunch left over from my last project. What is going to be your driver for the tractrix tweeter? Quote Link to comment Share on other sites More sharing options...

Mike Dubay Posted December 23, 2009 Share Posted December 23, 2009 Had a great listening session with Kevin last Sunday. The large mid horns do open up the sound. A very impressive sounding system! And Kevin still wants to tinker? The bug has bitten him badly. Quote Link to comment Share on other sites More sharing options...
kevinmi Posted December 24, 2009 Author Share Posted December 24, 2009 Yeah, Mike brought his hand made single ended amp over and we listened to some sweet 5 watt tube music! Now he's got me thinking of bi-amping the Behemoths! -Kevin Quote Link to comment Share on other sites More sharing options...

clermontcop Posted December 29, 2009 Share Posted December 29, 2009 Kevin those horns are crazy big. They are stunning to look at. I can only imagine what they sound like. Maybe if you turn them up enough I could hear them from where im at. Keep up the good work. I hope to have some more vinyl shipped out to you by week end. If not, it will be the first of the week.[H] Quote Link to comment Share on other sites More sharing options...
