ODS123 Posted November 26, 2018 Share Posted November 26, 2018 I would agree with those suggesting that you reach out to Klipsch. Though their warranty does not include coverage for damage arising from abuse (that it was unintended is beside the point), it would cost them next to nothing to keep happy a customer who bought their speakers new and from an authorized dealer. I'm betting they'll happily oblige. I would NOT recommend replacing the damaged tweeter with anything but the OEM part. I can't understand the thinking that some aftermarket vendor has come up with an improvement over what Klipsch has designed and engineered. Plus, if you need to sell them, I think it would hurt resale to modify them. Keep 'em stock - that's my $.02. Quote Link to comment Share on other sites More sharing options...

Ever see the FR and impulse response plots comparing the K-77 to the B&C de-120? Ever listen to a pair? Quote Link to comment Share on other sites More sharing options...

PrestonTom Posted November 26, 2018 Share Posted November 26, 2018 These are La Scala 2's (the system can't be very old) The diaphragm was accidentally fried. Yet, a bunch of you want the OP to spend a few hundred to "upgrade" the entire tweeter. This makes no sense. Fix them, enjoy them, and be done with it. BTW, the crossover may require alteration to accommodate a different brand of tweeter. Are you guys now going to suggest the OP "do this by ear"? 3 Quote Link to comment Share on other sites More sharing options...

JFHSQT Posted November 26, 2018 Author Share Posted November 26, 2018 Is simply replacing the diaphragm any more difficult than replacing the entire tweeter? Quote Link to comment Share on other sites More sharing options...
Deang Posted November 26, 2018 Share Posted November 26, 2018 Yes. Since you're not Mr. fixit, you can remove it, and send it to Bob for repair. You should definitely call Klipsch first and see if you get lucky. You will need the serial number of your loudspeaker. 2 Quote Link to comment Share on other sites More sharing options...

Thanks, I called the dealer to get some feedback from them before contacting Klipsch (they are only 6 months old), and will call Bob as well to see what he thinks. 1 Quote Link to comment Share on other sites More sharing options...
ODS123 Posted November 26, 2018 Share Posted November 26, 2018 Also, if these speakers are within the warranty period, wouldn't replacing the original tweeter with a non OEM part void the remaining warranty?? I can understand tinkering with different tweeters, etc.. in a 20 year old pair for which the OEM part is no longer available, but no way in a pair of speakers that are still in production. I would be skeptical of claims that replacing the original tweeter w/ an aftermarket part really improves the sound. I think that once someone has gone to the trouble of replacing it they will naturally be inclined to believe it sounds better even if it doesn't. I see big potential for placebo effect. 1 Quote Link to comment Share on other sites More sharing options...

Don't forget to physically inspect the network when you remove the tweeter. A burned up polyswitch or resistor would be pretty hard to miss.

PrestonTom Posted November 26, 2018 Share Posted November 26, 2018 Dean, or whoever else, doesn't it seem strange that a polyswitch would have not reacted quickly enough to protect the tweeter. I thought were capable of kicking in due to transients and turn-on thumps. Quote Link to comment Share on other sites More sharing options...
JFHSQT Posted November 26, 2018 Author Share Posted November 26, 2018 OK so I talked to Michael at Crites, and it seems like the CT 120 would require modification to my cabinet anyway, so not a good fit. As others have suggested, he also cautioned against voiding a warranty in a 6 month old speaker system... so it seems like the best route is to just go back to the dealer and see if they can negotiate replacement diaphragm under warranty and do the service work there. Which means I'll be missing my awesome speakers for at least several weeks if not longer. Local Craigslist has a pair of JBL L5s for sale. I wonder if those would be a good pinch hitter for the time being. 1 Quote Link to comment Share on other sites More sharing options...

There has been a lot of suggestions, guessing and assuming all weekend in this thread when IMHO you should give your dealer and Klipsch a chance to help resolve your problem. Maybe you can even continue to use them till repair parts can be shipped to you or the dealer. By the way even protection circuits have limits depending on the type of overload pulse they might have encountered and might not be able to protect in 100% of all cases. miketn 1 Quote Link to comment Share on other sites More sharing options...

I thought were capable of kicking in due to transients and turn-on thumps. We once had a really good thread about tweeter protection - some were adamant that a polyswitch was not always fast enough. DJK claimed auto bulbs worked the best. If I'm remembering right, he also preferred the zener diodes over the polyswitch. When the polyswitch tripped, current would have transferred to the resistor, and it apparently failed too. Quote Link to comment Share on other sites More sharing options...

JFHSQT Posted November 26, 2018 Author Share Posted November 26, 2018 Thanks Miketn and Dean, I think there's some good news here. I just spoke with the service department at Audiotronics here in Roanoke (where I bought the speakers) and he thinks Klipsch will send a new diaphragm under warranty with no issues, in just a few days from AR. It sounds like I'll just be able to bring the doghouse into the service dept and they can swap the diaphragm there, so this may not be as long-term an issue as I had feared. Although now I am kind of curious about those JBL L5s, haha. 2 1 Quote Link to comment Share on other sites More sharing options...
JFHSQT Posted November 26, 2018 Author Share Posted November 26, 2018 One idea just occurred to me, wondering if this is feasible or not. Since I do not biwire my La Scala IIs, I'm wondering if (until I get the tweeter swapped out) it would be possible to remove the biwire jumpers on the La Scalas and plug one set of speakers out from my Luxman L509X into the "Low" speaker posts on the La Scalas and plug another set of speaker outs from the Luxman into my RP-150Ms... and using the RP-150ms for the highs.

ODS123 Posted November 26, 2018 Share Posted November 26, 2018 Love your integrated choice, by the way!! The Luxman L509X is beautiful and feature packed. There are way too few integrated amps with bass, treble, mono switch. ..And for no particularly good reason, I might add. ..Well, there is a reason often cited - that they deteriorate the signal - but this is nonsense in my view. I view them as essential features to make it possible to enjoy ALL recorded music, including songs that need slight tonal adjustment or Stereo mix defeated. I would have bought the very same amp had I not bought my MA600. ,..I'm sure I would have been just as happy. 1 Quote Link to comment Share on other sites More sharing options...
