paully Posted July 9, 2007 Share Posted July 9, 2007 I managed to get hold of a pair of Chorus II. Very happy to have them. Apparently the wire has been upgraded (I will have to check that out) but the crossovers should be stock. Is it the opinion of the forum that the actual crossover needs to be upgraded or can I simply sub in newer components and leave the crossover circuit itself as is? Does anyone have a Klipsch crossover schematic that I can look at, or where to find one? The speakers wont be here for two weeks and I have to order some parts for another project. Thought, depending on the advice I get here, that I might go ahead and get the parts for the Chorus to avoid paying more for shipping if I am simply going to sub new parts in. Thanks!

Islander Posted July 9, 2007 Share Posted July 9, 2007 Try just listening to your new speakers for a while. You may be totally happy with them as they are. Quote Link to comment Share on other sites More sharing options...
lwhaples Posted July 9, 2007 Share Posted July 9, 2007 Congrats on the Chorus II's! Secound the listen first. Enjoy'em Larry Quote Link to comment Share on other sites More sharing options...
paully Posted July 9, 2007 Author Share Posted July 9, 2007 That is a definite. Even if I am set on upgrading the components, the capacitors at a bare minimum, I want to know what the changes will have done so I do need to listen first. I am just not sure if people have taken out the stock crossovers and simply replaced the components or are they buying completely new crossovers like they seem to be doing for the La Scalas and Khorns.

Moderators dtel's wife Posted July 9, 2007 Moderators Share Posted July 9, 2007 Paully, Congrats on the Chorus II. Take some time to listen to your speakers, you may find they are in perfect working order and you don't need to change out a thing. After a few listening sessions you will have a lot better idea. But....in the meantime I am sure some of these guys could help you out with the info you are looking for. Again, congratulations. Quote Link to comment Share on other sites More sharing options...
meagain Posted July 9, 2007 Share Posted July 9, 2007 Congrats Paully! I have Chorus II's and think they're great speakers. I've not upgraded the crossovers in mine cuz they aren't being used right now. Quote Link to comment Share on other sites More sharing options...
DrWho Posted July 9, 2007 Share Posted July 9, 2007 As far as I know, my Chorus II's are stock. I have measured them in quite a few environments and have not come across anything that might hint at a need for a crossover change. My ears tell me the same, but that's kinda implied. I must confess that I have thought about modify things a bit just for the sake of experimenting, but it's kinda pointless when there really aren't any objective gains to be achieved. That's not to say that improvements aren't possible, just that there are much larger issues to be dealing with. Heck, you could move the speakers as much as a few inches in your room and yield more dramatic changes than any crossover change will make [] Quote Link to comment Share on other sites More sharing options...
stormin Posted July 9, 2007 Share Posted July 9, 2007 Congrats on the Chorus II's. I think you have acquired a great speaker[Y] Quote Link to comment Share on other sites More sharing options...
paully Posted July 9, 2007 Author Share Posted July 9, 2007 Thanks to all, I am really happy to have them. Had thought about getting a pair of La Scalas, and I probably still will, but these came up and I just had to have them. Quote Link to comment Share on other sites More sharing options...
paully Posted July 9, 2007 Author Share Posted July 9, 2007 Thanks. I read a lot before I bought these and it seemed that these were a real sleeper. Everyone who has them, save for the odd duck, thinks they are wonderful. Even if I get other Klisch speakers (it seems very few have only one pair) it seemed like these needed to be in the collection as the Cornwalls are just too big. Can't wait to actually have them show up. Quote Link to comment Share on other sites More sharing options...
paully Posted July 9, 2007 Author Share Posted July 9, 2007 Interesting. I would have thought you would be keen to upgrade the capacitors. I would think that, as the speaker was designed in the 90's, that the crossovers ought to be pretty good as far as design goes. But that maybe putting in some auricaps or such would be worthwhile. I do agree, listen to them for a while and then decide because they just might be really good anyway. I guess I am just one of those designer cap kind of guys. Just can't help tweaking sometimes. I will post back after I have had some time to sit with them stock. Quote Link to comment Share on other sites More sharing options...
DrWho Posted July 9, 2007 Share Posted July 9, 2007 I'm an electrical engineer (soon to be)....we're not into the fancy stuff [] I would put more faith into DC biasing the caps than expensive materials. Quote Link to comment Share on other sites More sharing options...
WMcD Posted July 9, 2007 Share Posted July 9, 2007 Congrats on the purchase. I'm a big fan of the Quartet, Forte II, and Chorus II line. I have the first two but have never heard a Chorus II. It seems to me there is no reason to rush into a rebuild. Bob Crites, a forum member here, sells aftermarket parts. He is not affiliated with Klipsch, the company. But because of his business, he has a lot of experience with replacements and perhaps what is a situation of a cap going off specification because of age. You might know that the old Heritage speakers used paper in oil caps. These are the metal can type. Some of the Heritage units out there are 50 years old. Those caps sometimes fail due to leakage of oil. A matter requiring replacement. Bob reports that some of these caps also go off spec and develop internal electrical resistance. I'm taking no position on the extent of this problem. But, the Q,FII, CII, series use more modern caps. And they are not nearly as old, of course. Therefore, they should remain in spec. Hence there is little reason to think your components are degraded. I will point out that many people believe in upgrading and tweeking. It is part of the fun of the hobby.

I have the first two but have never heard a Chorus II.Look me up if you ever find yourself down in Champaign/Urbana. Maybe we can meet up some evening for a concert over at Foellinger?But seriously, anyone is welcome to swing by for a visit. Quote Link to comment Share on other sites More sharing options...
WMcD Posted July 10, 2007 Share Posted July 10, 2007 This was on the forum, someplace. I'll be Bob Crites posted it after obtaining it from Klipsch. Gil Quote Link to comment Share on other sites More sharing options...
paully Posted July 10, 2007 Author Share Posted July 10, 2007 Marvelous, thank you! I wonder what the voltage on the capacitors is. Quote Link to comment Share on other sites More sharing options...
WMcD Posted July 10, 2007 Share Posted July 10, 2007 I don't know the voltage rating on yours. Maybe if you take them apart the caps will be marked. Here is the schematic for an RF7. It uses 100 volt caps. I'd say there is a good chance yours, and other Klipsch, are also 100 volt caps. Best, Gil RF7.pdf Quote Link to comment Share on other sites More sharing options...
DrWho Posted July 11, 2007 Share Posted July 11, 2007 At 1000W peak into 8 ohms, you're talking 90 volts from the amp. Anything over 100V is gonna be way overkill. Quote Link to comment Share on other sites More sharing options...
mikieboyblue Posted July 13, 2007 Share Posted July 13, 2007 I am in the a similar boat but know nothing about this stuff and reading half of it is confusing to me... I have a thread in another forum (http://forums.klipsch.com/forums/thread/939005.aspx). I will be watching this one. How do I test the crossover?

DrWho Posted July 13, 2007 Share Posted July 13, 2007 I would probably start with learning this program: http://www.audua.com/ Quote Link to comment Share on other sites More sharing options...
