soundbound Posted September 22, 2009 Share Posted September 22, 2009 Great job! I might build me some. Quote Link to comment Share on other sites More sharing options...
kg4guy Posted September 22, 2009 Author Share Posted September 22, 2009 Because Parts Express is out of stock on adapters I had to improvise and cut the adapter from the APT 80 horn lens. Watch out for those digits... Orange County Speaker includes the adapter in the price when you buy the APT-50 .Wow Dave I like that horn much better where can you get those?

Guest David H Posted September 22, 2009 Share Posted September 22, 2009 I found those horns on EBay, I think they are from the KSB series speakers. Quote Link to comment Share on other sites More sharing options...
Invidiosulus Posted September 22, 2009 Share Posted September 22, 2009 I found those horns on EBay, I think they are from the KSB series speakers. I think that's right.It looks like the one I've got in my SC1 center channel, IIRC it has a silk dome compression driver or something in the back. Something I've noticed with the K77's and with Bob's CT-125 is that the vertical dispersion really seems pretty narrow so switching to one of the other horns may help alot with placement and soundstage.

Tony Reed Posted November 1, 2009 Share Posted November 1, 2009 GotHover, Very cool... looks like it was made that way. Let us know what you think of the sound. Tony Quote Link to comment Share on other sites More sharing options...
Guest David H Posted November 2, 2009 Share Posted November 2, 2009 I am please with the tweeters outcome. As for the sound, I have not mounted these in anything for extended use but they sound very good in testing. Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted November 2, 2009 Share Posted November 2, 2009 I am confused. There seems to be 2 different combos. What are the options as to drivers and horns? Anyone care to summarize? I also remember reading about a budget midraneg driver by Silenium. Anyone remember what that one was? Quote Link to comment Share on other sites More sharing options...
Guest David H Posted November 2, 2009 Share Posted November 2, 2009 The Selenium D250-X is the budget mid driver, however it rolls off 3500-4000hz. Attached is an in room graph of the D250X coupled to my Fastrac Horn. I am confused. There seems to be 2 different combos. You are not confused, I simply added another possible combination for those that choose to front mount the tweeter and prefer tractrix lenses.

hklinker Posted November 10, 2009 Share Posted November 10, 2009 Because Parts Express is out of stock on adapters I had to improvise and cut the adapter from the APT 80 horn lens.

Good News!Parts Express now has the adaptors back in stock! http://www.parts-express.com/pe/pshowdetl.cfm?Partnumber=290-539 Herb Quote Link to comment Share on other sites More sharing options...
longdrive03 Posted January 11, 2010 Share Posted January 11, 2010 This method should also work for this horn, correct? Quote Link to comment Share on other sites More sharing options...
freddyi Posted January 12, 2010 Share Posted January 12, 2010 what happens with APT50/APT3 on K703? - waste of real estate? Quote Link to comment Share on other sites More sharing options...
Guest David H Posted January 12, 2010 Share Posted January 12, 2010 what happens with APT50/APT3 on K703? - waste of real estate? Dont know, that post just showed up yesterday. The mounting idea should work for that lens as long as it is a one inch. Quote Link to comment Share on other sites More sharing options...
freddyi Posted January 12, 2010 Share Posted January 12, 2010 do you think K94's profile worked out better than the piezo horn - or just different - or not much different? (looking at the saw work makes me think of CTS KSN1142 with its horrible rod-phase plug and dips/peaks - removing some of 1142's plug and threads might help -?) can KSN1016 on stepup compete with APT50 on a rectangular K77 size lens with regard to output and quality?

Guest David H Posted January 13, 2010 Share Posted January 13, 2010 do you think K94's profile worked out better than the piezo horn - or just different - or not much different? Because both share the same driver, they are sonically similar. can KSN1016 on stepup compete with APT50 on a rectangular K77 size lens with regard to output and quality? The 1016 mated to an APT 50 is definately a suitable replacement for the K-77, I am not sure what you mean by stepup.(looking at the saw work makes me think of CTS KSN1142 with its horrible rod-phase plug and dips/peaks - removing some of 1142's plug and threads might help -?) Not sure, may be worth a try. Quote Link to comment Share on other sites More sharing options...
freddyi Posted January 13, 2010 Share Posted January 13, 2010 I meant using KSN1016 instead of APT50/small lens using a 25v line tranfromer driven backwards to step up the voltage to the piezo - in the case below 1uF highpass to 100uH/8R Zobel and 56R to the tweeter - Xover is a bit too low with 1uF Quote Link to comment Share on other sites More sharing options...

djk Posted January 14, 2010 Share Posted January 14, 2010 And not having heard it, what is your opinion worth? Genuine Motorola/CTS piezos sound great (with a proper crossover). Quote Link to comment Share on other sites More sharing options...
Guest David H Posted January 14, 2010 Share Posted January 14, 2010 And not having heard it, what is your opinion worth? Your reply is uncalled for but correct. I have very little experiance with this tweeter, therefore I would be happy to withdraw my previous comment. However I would not use it based on the limited experience I have had with them.

freddyi Posted January 14, 2010 Share Posted January 14, 2010 hi DJK - for Klipsch style application what values for Zoebel and crossover should be considered? - -there's a small chance I cooked a KSN1016 using 1uF highpass - it seemed to lose sensitivity (?) - IIRC my test originally gave ~103 or so dB 2.83vrms 1M - distortion at 103dB/1M/5029hz was ~1/4 of 1% Quote Link to comment Share on other sites More sharing options...
Johnny's Jill Posted January 16, 2010 Share Posted January 16, 2010 Genuine Motorola/CTS piezos sound great (with a proper crossover). Like what balled up wire and a few electrolytics? I will stick with my JBL's. These piezos have been used for years in low buck pro gear, and are not well suited for home use. Quote Link to comment Share on other sites More sharing options...
