TJIann Posted January 24, 2015 Share Posted January 24, 2015 Ok. I have CWIIs and am going to do a Crites upgrade by replacing the crossover (this is the one on back of the input cover) and replace the tweeter diaphram with Bobs titanium one. Who here has CIIs and has done these mods? How's the improvement in your opinion? Other alternatives (for CIIs, not other versiins) that you have found are better? Thanks.

Thanks. - I did a setup that upgraded the caps and the titanium diaphragms - I found the titanium too bright at first but it did settle in after a month or so - will you part with the crossovers or just do the upgrade of the caps - I am interested in the CWII stock crossovers if you decide to sell these - Quote Link to comment Share on other sites More sharing options...
OO1 Posted January 25, 2015 Share Posted January 25, 2015 (edited) The upgrades of the mids and tweeter diaphragms is best as well as these are old after 30 years of usage - old caps - old diaphragms - woofers are the only items that last - even new non-titanium diaphragms will sound better than the current - titanium will have a brighter tone - if you listen to classical music , you will notice improvement with the acoustics - Edited January 25, 2015 by Randyh 1 Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted January 25, 2015 Share Posted January 25, 2015 That cabinet has no internal damping and resonates at high volumes. 1" thick acoustic foam on the three non opposing sides will make a nice difference. The crossover network in the CII looks like it was built by playschool. I would spend some money on a different crossover design rather than replacing the original with marginally better parts. Not a fan at all of the titanium diaphrams they are screechy and sizzly sounding as compared to the original phenolic diaphrams. YMMV 3 Quote Link to comment Share on other sites More sharing options...

Not a fan at all of the titanium diaphrams they are screechy and sizzly sounding as compared to the original phenolic diaphrams. YMMV from what you are saying - The CW II cabinets dont have the acoustic foam that came in the CW1 from the factory - hence , the MDF resonates as a consequence of this missing in the cabinet - do you know if that applies as well to the CW3 - I am surprised that the tests in the anechoic chamber at Klipsch in Hope Ark didnt show the issue of resonance - 2 Quote Link to comment Share on other sites More sharing options...

PrestonTom Posted January 26, 2015 Share Posted January 26, 2015 (edited) I would not worry about putting stuffing in the cabinet if it was not there originally. BTW, it will have no impact on the MDF resonating Edited January 26, 2015 by PrestonTom 1 Quote Link to comment Share on other sites More sharing options...
Lemon string Posted January 26, 2015 Share Posted January 26, 2015 (edited) i have CWII's and updated/upgraded the x overs, with a different vendor, it was a GREAT upgrade. I have also replaced the original tweeters with Bobs Ti diaphragms, I never found them to be harsh in my room but they did clean up the soundstage and are more articulate imo. In addition I replaced the the stock woofers with Eminence Kappa 15c's from parts express. This really cleaned up the mid lows and the bass response is way tighter. I've considered replacing the mid diaphragms but Bob didn't seem to strongly advocate it so at this point I haven't. Good luck Edited January 27, 2015 by Lemon string 2 Quote Link to comment Share on other sites More sharing options...

Good luck - -I would have thought that the KAPPA C was more like a k43 - less bass -as these need 4x more power -the k33 is a 100 watts woofer versus the Kappa C 's 400 plus - please can you give us your feedback -tx Edited January 26, 2015 by Randyh 1 Quote Link to comment Share on other sites More sharing options...

TJIann Posted March 19, 2015 Author Share Posted March 19, 2015 Just got done installing new Crites crossovers and titanium tweeter diaphragms in my CIIs tonight. Wow, what a difference! Stunning. What a difference in crossover quality of build too! Bob and his son do great work. 1 Quote Link to comment Share on other sites More sharing options...
