Audio Flynn Posted January 3, 2009 Share Posted January 3, 2009 The thread about what people did for their systems this year made me laugh. Upgrades you avoid one year leave discoveries in the next. Avoiding the upgrade bug for a year is tough. If the economy gets a little better I am thinking my Belles may need a little modding. I have not touched them since Dean made me the ALK Jrs. about 1.5 years ago. What would you do first? Tweeters or trachorns? If tweeters which one?

joshnich Posted January 4, 2009 Share Posted January 4, 2009 Agree. Trachorn was the most significant upgrade for my belles. Josh Quote Link to comment Share on other sites More sharing options...
NOSValves Posted January 4, 2009 Share Posted January 4, 2009 Trachorn.... No doubt about it.... If you want to play with tweeters come on up here I have at least 2 extra sets that will bolt right in. One set of Bob Crites new replacements and one of his early endeavers with a stock klispch K77 with some type of extra large heavy duty magnet or something Dean talked me into LOL!! I'm now using the proper Eminence baby cheek horn lense designed for the APT-50 driver http://www.parts-express.com/pe/showdetl.cfm?Partnumber=290-530 that Bob is using in his current aftermarket tweeter. I think AL K. can fit a baby cheek type horn in his trachorn modification for a Bell speaker. Nice thing about the Eminence APT-200 tweeter and Bob bolt in replacement is it seems to blend perfectly without tweeter attentuation.

DrWho Posted January 4, 2009 Share Posted January 4, 2009 I'd take care of both by going 2-way...lots of options there depending on how much you're willing to spend. Quote Link to comment Share on other sites More sharing options...

It is the same APT-50 driver on a 100x50 horn. I still have Bob's CT125s mounted in the cabinet. Quote Link to comment Share on other sites More sharing options...
Audio Flynn Posted January 5, 2009 Author Share Posted January 5, 2009 I had a feeling I was going to have to do some "surgery "on the ladies to go to the next level. I will have to read up on the details it has been well over a year since I read about the process to integrate the trachorns intothhe Belles and it has been a rough year.

db101 Posted January 8, 2009 Share Posted January 8, 2009 Perhaps someone can tell me if this apt-50 driver with adaptor will work on the tweets of my 77 Cornwalls? It seems that sometimes I'm missing a bit of upper end extension but not sure if it's the tweeter or the limited bandwidth of my 2A3 mono's. Thanks, Greg Quote Link to comment Share on other sites More sharing options...

Trachorns - It's a slam dunk..........you live in the midrange ----- Tweeters marginal Positively, absolutely 100% agree! Trachorns first, followed by ALK's "Extreme Slope" networks... tweeters pretty much last. Have a super weekend! Rob Quote Link to comment Share on other sites More sharing options...
djk Posted January 10, 2009 Share Posted January 10, 2009 "tweeters pretty much last." I think the K77 sounds like a nail; bright, but no real high end. I would replace it before blowing big bucks on the networks. Quote Link to comment Share on other sites More sharing options...

And the "big bucks" spent on the "ES" networks was money [very] well spent, not "blown" by any stretch of the imagination. Rob Quote Link to comment Share on other sites More sharing options...

No amplifier or xover will fix distortion/resonances from a driver unless you're moving the sources out of the passband (which isn't the case in this situation). Also, xovers need to be designed for the drivers you're using. Buying expensive crossovers first seems totally backwards if you're gonna change the tweets later on. Really, the xover should be modified at the same time as the driver change and the driver should dictate what the xover needs to do. Quote Link to comment Share on other sites More sharing options...
