justinsweber Posted February 25, 2011 Share Posted February 25, 2011 hey Everyone, I have a wonderful setup currently, Split Corn Scalas (eminence Kappa 15 c for the bottom). K400/K55, Selenium D220ti up top. That said, I have been planing a move to 2" horn (JBL knockoff) I just saw on Bob Crites site that he now has made a 2way Cornscala (Faital HF200 driver) and a match crossover. Option 1. 3way Selenium D220ti, M2380 horn/Selenium D405 Opttion 2. 2way M2380 horn/Faital HF200 I already have the D405 and D220ti but if the 2way is that much better then changing course now woudl be worth while. Sugestions? Quote Link to comment Share on other sites More sharing options...
tomlang Posted February 25, 2011 Share Posted February 25, 2011 I will vote for Option 2 but am biased since I was thinking the two way also. I just emailed Bob about the M2380 JBL clone and also asked about the CS500 two way crossover for this. Here is his response -- "Just this last weekend, we finalized the 2-way crossover for the Cornscala. It is a 2nd order on both the LF and HF and uses an autotransformer. Yes, the crossover point is 500hz." Quote Link to comment Share on other sites More sharing options...
Guest David H Posted February 25, 2011 Share Posted February 25, 2011 I am leaning towards a 2-way Cornscala as well. I plan on using my Eliptrac horn(obviously) and an ALK AP-12 600 crossover with the Faital Pro. Dave Quote Link to comment Share on other sites More sharing options...
justinsweber Posted February 25, 2011 Author Share Posted February 25, 2011 The real question is if I can sell my D405s... I never used and bought in advance. :-(. If not the economics seems to favor the 3way. Quote Link to comment Share on other sites More sharing options...
tomlang Posted February 25, 2011 Share Posted February 25, 2011 It seems Faital HF200 has a remarkably flat response for a compression driver. That said, can a near "textbook" crossover be used or does it need HF compensation? I guess I should have asked first does the ALK AP-12 600 have HF comp?

The AP-12 600 does not have HF compensation and the Faital pro doesn't seem to need it. Quote Link to comment Share on other sites More sharing options...
BEC Posted February 25, 2011 Share Posted February 25, 2011 Dave, I tried a crossover frequency of 500 and 600 on mine. FR looked a bit better at 500. Bob Crites Quote Link to comment Share on other sites More sharing options...

justinsweber Posted February 26, 2011 Author Share Posted February 26, 2011 I sold my D405s, and bought the new drivers from bob. Ill have some save some coin to get the corssovers and horns, but this seems the best I could get so its progress. Quote Link to comment Share on other sites More sharing options...
tomlang Posted February 26, 2011 Share Posted February 26, 2011 OK, help me out with this. The resonance of the HF200 appears to be about 540 Hz as indicated by an impedance peak. Is there an issue (or compromises) with crossing over lower than this frequency? Apparently not in this case, but in general is this avoided with HF drivers? Also, let me get this straight. Even though the specs call for <no lower than> a 12db crossover at 900 Hz, in fact Bob has it crossed at 500 Hz (12 db) and furthermore has tested it even lower, according to his website -- "I have run this driver at high power (around 100 watts per channel) for quite awhile with no problems crossed at 400hz (?db/octave?) in a Cornscala. The Cornscala does not need to cross that low, but the test proved the Faital Pro HF200 drivers should be safe crossed at 400hz in a Khorn." So this is one rugged, accurate driver indeed. Seems like a bargain to me. Quote Link to comment Share on other sites More sharing options...
Guest David H Posted February 26, 2011 Share Posted February 26, 2011 Tom, ALK and Lee Clinton also did testing on this driver and the general consensus is that it is ok to cross the HF-200 as low as 400hz, Atleast in a home setting. Lots of measurements here http://forums.klipsch.com/forums/t/144319.aspx Quote Link to comment Share on other sites More sharing options...
