MOEB74 Posted December 13, 2017 Report Share Posted December 13, 2017 Looking for a guru's input on this, or really anyone that understands these things. I bought set of these speakers with the crossovers already recapped. I trust the guy that did the work, he has a good rep on the AK.com forum. I dont know how many he has done, but he has been honest with me and I dont get any bad vibes. Question is, that one speaker is brighter than the other. If I use the above 7000 CPS selector it sounds closer to the other. But still not 100%.. Any idea why? I thought maybe the receiver was dying or a section was, so I swapped the speaker wires and the one speaker still sounds brighter, hence me pointing to that particular speaker's crossover. thanks!

dxho Posted December 14, 2017 Report Share Posted December 14, 2017 Or the drivers... they're ~40 years old. There could be some variations in output by now. Link to comment Share on other sites More sharing options...
MOEB74 Posted December 14, 2017 Author Report Share Posted December 14, 2017 Interesting, I always thought that the issues were always in the crossover and not the actual speaker. I kind of though that the speaker was either good or bad. How can the driver itself cause it to be too bright or less bright? Link to comment Share on other sites More sharing options...

Or, as dxho says, it could be the drivers. Link to comment Share on other sites More sharing options...
MOEB74 Posted December 15, 2017 Author Report Share Posted December 15, 2017 True.... I would hate to have to remove these woofers again to gain access to the crossover, unless I have to remove a different driver? Link to comment Share on other sites More sharing options...
lARrybody Posted December 16, 2017 Report Share Posted December 16, 2017 Were the resisters also replaced with the recap? i hope the new caps were measured to make sure they are in spec and close to each other? By swapping drivers you can determine if one has diminished output. It's a process of elimination. Link to comment Share on other sites More sharing options...

KLH used 5w resistors in the Five and the similar Twelve and I've seen scorched resistors in both models. Link to comment Share on other sites More sharing options...
Markkb Posted March 12, 2018 Report Share Posted March 12, 2018 If I recall correctly, there is a dual-capacitor with two different values in one capacitor. When rebuilding, one replaces that cap with two separate capacitors. I remember someone advising to ensure that you test the leads of the dual cap prior to removal to verify which replacement capacitor goes where. That is one place to make a mistake if I’m not mistaken. Link to comment Share on other sites More sharing options...
