wafish Posted November 12, 2013 Share Posted November 12, 2013 Greetings Klipsch community from a new member , long time corner horn owner. My latest purchase is a set of kg 2.5 that I plan to give to my son to get him started in the right direction. The problem that I have with these speakers; I suspect the caps need to be replaced. Seems as though I have to drive them pretty hard to get much volume out of them. Plenty of base for there size but very lacking in mids and highs. I may not be the best judge of these little things since Im accustomed to listening to my horns but judging by the amount that I have to turn up the preamp on my mac verses the number of watts the meters say that Im outputting to them it seems like they just wont take the power. Is it possible that the caps are bad and the speakers as a whole are acting like resistors? Also was wondering where I can get a schematic for the crossovers on these little dudes. Any help would sure be appreciated, Walt Quote Link to comment Share on other sites More sharing options...
Deang Posted November 12, 2013 Share Posted November 12, 2013 Are you sure you're getting output from both midrange drivers and tweeters? Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted November 12, 2013 Share Posted November 12, 2013 huge difference in efficiency. Quote Link to comment Share on other sites More sharing options...
Deang Posted November 12, 2013 Share Posted November 12, 2013 You mean -- between what he's used to and the KGs? Sure, but they shouldn't sound "broken". OTOH, rereading the post, he never said for sure whether something sounded broken or not. Quote Link to comment Share on other sites More sharing options...
wafish Posted November 12, 2013 Author Share Posted November 12, 2013 yes there is output from all drivers, and yes I know Im a bad judge because of the efficiency of what Im accustomed to listening to but it seems as though the longer they play the better they get. Im still scratching my head. I wouldn't mind to recap them before I give them to junior but after looking at the crossovers on one Im not sure by sight if there are 2 or 4 caps. Hoping to get a schematic to be sure. Thanks for the input Quote Link to comment Share on other sites More sharing options...
Deang Posted November 12, 2013 Share Posted November 12, 2013 I can post one for you later. 1 Quote Link to comment Share on other sites More sharing options...
cheric Posted November 12, 2013 Share Posted November 12, 2013 The orange left cap is a 25uf/100vThe orange right cap is an 18uf/100vThe big brown cap (left/center) is an 8uf... and...the smaller brown cap (right/center) is a 4uf Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted November 12, 2013 Share Posted November 12, 2013 Dean, I have 2.5's and 2.2's. Please do post the schematic. Thanks. Quote Link to comment Share on other sites More sharing options...
BEC Posted November 12, 2013 Share Posted November 12, 2013 Here is the schematic for the KG-2.5. Not sure this the only version of that crossovers since this one is called the KG-2.5B schematic.

Deang Posted November 13, 2013 Share Posted November 13, 2013 I have the same schematic Bob has, which means I probably got it from him or the same source. The resistors and capacitors are the same values as what Cheric posted. The only thing left is the coils, which are probably the same too. Revisions sometimes only involve small things, like possibly a switch in the vendor making the boards, lead lengths, etc. Quote Link to comment Share on other sites More sharing options...
cheric Posted November 13, 2013 Share Posted November 13, 2013 (edited) KG 2.2 and KG 2.5 have some minor differences on the caps on their crossovers. On the KG 2.2... The two purple left caps are a 25uf/100vThe big blue cap (left/center) is an 8uf... and...the smaller blue cap (right/center) is a 4uf Edited November 13, 2013 by cheric Quote Link to comment Share on other sites More sharing options...
wafish Posted November 13, 2013 Author Share Posted November 13, 2013 wow,you guys are awesome!(at the risk of sounding like one of my kids) really appreciate the help! I thought those orange thingies might be caps,lol Thanks again, Walt Quote Link to comment Share on other sites More sharing options...

cheric Posted November 13, 2013 Share Posted November 13, 2013 (edited) btw, any advice on what kind of caps to use....anyone hear the can of worms open? I have no opinions on capacitors. I have no recommendations on caps either. Yesterday was Veterans day and war should not start the day after.

wafish Posted November 13, 2013 Author Share Posted November 13, 2013 lol, didn't wanna start a war or skirmish (if I spelled that right) just looking for advice. never fooled with caps on a board before so obviously I haven't messed with radial caps. Anyone willing to give direction of where to look would help, Quote Link to comment Share on other sites More sharing options...

Anyone willing to give direction of where to look would help, Parts-express.com would be a good place. The 25uf and 18uf (orange ones) could be electrolytic caps and the 8uf and 4uf (brown ones) could be the Dayton polypropylene caps. Cost about $20 plus shipping. http://www.parts-express.com/cat/crossover-capacitors/292 2 Quote Link to comment Share on other sites More sharing options...
