bribassguy Posted December 1, 2011 Share Posted December 1, 2011 I have a RC-35 that sounds muffled. I ran calibration w/o any improvment, then manually ran test tones and leveled the volume of the channels w/o any improvment. I tried to adjust the EQ again w/o any improvments... I reset everything in the reciver and then I switched the front channel RC-35 to a RB-35 and it made a world of differance. That seems to eliminate the amp / reciver as a problem. After that I switched them back and ran test tones for JUST the high freq inputs and the center channel was WAY low. I was thinking it had to be the X-over or tweeter at that point. I pulled off the front covers and it looks like the high inputs by-pass the tweeter completly. I check impendance then used a battery to "click" the tweeter... there was a very faint clicking but my multi meter seems to bleed down the ohm reading or slowly count down. I pulled off the front cover of my RB-35 to try and compare to see if I could hear / measure a differance and noticed that they have compeltly diffrent driver designs. The 'dead' sounding RC has a K-130 tweeter that is flat on the back whereas the RB has a K-137 tweeter with a large heatsink. I am scratching my head a little trying to diangonse the issue. I am thinking that the tweeter is bad, what do you guys think? Am I missing something? Thanks for any help, BCM Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted December 1, 2011 Share Posted December 1, 2011 If there is a metal jumper to connect high and low do you have it connected? Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted December 1, 2011 Share Posted December 1, 2011 Has it always sounded this way (is the speaker new to you) ore is this something that just happened? Quote Link to comment Share on other sites More sharing options...
bribassguy Posted December 1, 2011 Author Share Posted December 1, 2011 It is a new to me speaker... it always sounded funny to me. When replaced with an rb-35 everything sounds as expected. Quote Link to comment Share on other sites More sharing options...

I had an RC-35 when they first came out. Mine was a little muted on the top end but I read a lot of complaints about people complaining that the speaker sounding muffled. Some described it as sounding like it was being played in a box. Others said it sounded like there was a towel draped over it. I'll see if I can find some of the old posts.

I don't recall reading what the problem actually was, the tweeter or the crossover. If you switch tweeters and still have the issue, then the problem is in the crossover. I wouldn't know where to start with that repair. Quote Link to comment Share on other sites More sharing options...
bribassguy Posted December 1, 2011 Author Share Posted December 1, 2011 I swapped the K130 for the K137... everything is much much cleaner. I'll give it a good listening test tonight and report back but for now it looks like I'll be needing a new one from Klipsch. I hope this is under warranty.
