SilverSport Posted August 9, 2009 Share Posted August 9, 2009 I have been a happy customer of Bob Crites since I had him freshen thecrossovers in a pair of Heresys (1978) some years ago...Since then I had another set of Heresys (1980) renewed...I've evenbought a pair of Bob's K-77 replacements across the front of my HeresyHome Theater...I renewed and improved a pair of Quartets by newcrossovers, getting them off the fragile terminal cup and then addingTitanium diaphragms...I was so pleased with the clearer upper range of the Quartet (where ittakes a back seat to the Heresy) that I tried the Titanium diaphragmson a pair of KG 5.5s...same result...clearer and extended highs...wellworth the price of admission and if this all thumbed, seemingly noneapposable installer can do it you can...Today I took on a more difficult undertaking...adding a third set ofTitanium diaphragms to a pair of Chorus IIs...it is more difficultbecause the previous owner glued on bucking magnets on all threespeakers...not only can't the tweeter come out the front as it wasdesigned but it weighs a lot...making these Chorus IIs over 100lbs...but hey...that's half the fun isn't it???after some drama (it's all about the drama isn't it? ) I have them back together...hooked up and right now I am listening to some really great Eagles (Hell Freezes Over)...yum!Yes, I tried the sound with one new Titanium diaphragm and onephenolic...I thought they both sounded nice...the phenolic, what I wasused to and had been listening to for a month or so and theTitanium???...nice but clearer and cleaner.If I have used any audiophile terms, it is merely a coincidence as thatis not my area of expertise...as for Bob Crites...well...A+++ and ifanyone is still on the fence over these Titanium diaphragmupgrades...getchusome...Bill Quote Link to comment Share on other sites More sharing options...
jcmusic Posted August 9, 2009 Share Posted August 9, 2009 Does Bob have these for the K-77's? Jay Quote Link to comment Share on other sites More sharing options...
SilverSport Posted August 9, 2009 Author Share Posted August 9, 2009 I don't believe they have them for us with older Heritage...(he didn't when I checked a couple of months back) Bill Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted August 9, 2009 Share Posted August 9, 2009 I felt that there was a much more noticeable upgrade when I installed the Ti tweeters compared to the crossover networks. Quote Link to comment Share on other sites More sharing options...
Islander Posted August 9, 2009 Share Posted August 9, 2009 Does Bob have these for the K-77's? Bob has the CT125 tweeters, which are a definite improvement over the K-77s. Quote Link to comment Share on other sites More sharing options...
youngjj Posted August 10, 2009 Share Posted August 10, 2009 Wuzzer, how difficult was the upgrade to titanium diaphragms? You did that on your Forte IIs, right? Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted August 10, 2009 Share Posted August 10, 2009 Wuzzer, how difficult was the upgrade to titanium diaphragms? You did that on your Forte IIs, right? Ridiculously easy. Bob has a step-by-step guide on his website on how to do it. Took all of 10 minutes per side. The only thing that's slightly difficult is installing the horn back in the cabinet because it has to be inserted at just the right angle. It does help to have a needle nose pliers as stated on his website to remove the screws holding the horn onto the diaphragm/magnet. Here's the link: http://critesspeakers.com/replacing_the_diaphragm_on_.html Well worth the money in my opinion. Quote Link to comment Share on other sites More sharing options...
tyler8 Posted August 11, 2009 Share Posted August 11, 2009 Found the tweeter upgrade to my Forte II's easy as well. Now I need the CT125 upgrade for my Cornwalls having already done the caps. Easy mods. Quote Link to comment Share on other sites More sharing options...
