    RF-7 mk1 - tech help

    in Technical/Restorations

    Posted

    Sounds like you voice coils are rubbing. The voice coils themselves can be replaced. Do some googling and youtube'ing for info. 
    Have tried Google, no luck. Can't find reconing kit anywhere.

    And I'm also looking towards replacing the woofers with some matching speakers. Does anyone know of any good replacement speakers?

    Other than measuring, have you listened to the speakers?
    A couple of things, you may want to look for used in the usual places, starting with the Garage Sale section here.
    And, cannot recall the size or model number of the RC-7 center speaker. 
    Welcome to the forum!
    BTW, if want place an ad in section here for WTBuy etc.. 
    Have no sound other than from the tweeters. And when I move the woofers membrane I can hear it scratches against something.

    I'll shall try to put in a advertisement for use woofers. But, as my location is in Norway (Europe), there aren't probably many sellers that are willing to ship abroad /international. But of course, worth a shot. :)

    Hi

     

    I have gotten hold on a pair of RF-7 from 2005. They are in a really bad shape, so I got them cheap(?), about $150 for the pair.

     

    Had to take them as is.

     

    So, now I have checked the technical state of the speakers, and this is the list:

     

    Tweeters measures fine in to 8ohm.

     

    All the the bass/mid drivers are measuring as defective, except for one.

     

    The crossovers seems to be fine, but haven't measured any components on them.

     

    So, if I'm correct, I'll need new replacements for the bass/mid drivers. Question is, are there any place to new one's? If so, where's that. And yes, I have checked at speaker exchange.

     

    If there are no new genuine Klipsch speakers available, are there any other replacement parts available?

     

    Any tip is most appreciated! 5fb58a7d3ef0111ceef9dcb9305af5bb.jpg

    K-48-EP woofer

    in Klipsch Pro Audio

    Posted

    the Lascala pro model  uses  a K43   4ohms   ,  it's not a k-48 ,8 ohms   ----------- and a K43 is not a good replacement for a K48    -
    I remembered it wrong, the woofer is a 4ohm driver. The speaker is 8ohm total.

    So that's explaining why the seller of the used K-48 is selling. He has an K-48 now, seen pictures, and want the original driver in.

    Question is, go for the used K-48, new one for Chorus II (cost $100 more) or just use the one from my KP-115 that's also marked K-48?

    I have read here in the forum that there aren't really any differences between K-48 other than manufacture, that they are build to same specs. Can anyone confirm or not that that is the case?

    K-48-EP woofer

    Thanks for the input.

    I'm hoping that the crossover is fine. To me it seems like the units have been driven hard for a longer period of time, the voice coil is lose from the defective K-48-EP driver.

    So, I'm actually more concerned about the woofer that's measured fine in to 8 ohms. What's the actual status of the that driver, and how long will it work?Just have to try out and see I guess.

    I have the possibility to buy a new K-48 for Chorus II or a used K-48 driver from a lascala pro model. Would any of these two be a good replacement you think?

    Here is some pictures of the speakers:

    K-48-EP woofer

    in Klipsch Pro Audio

    Hi

     

    I have a pair of KI-362, haven't testet them yet so I'm quite excited. Anyone with any experience on these puppies? Intended use is as front LR in mye home theater setup. I swapping these in for the KP-262.

     

    Anyhow, the reason why I haven't tested them yet is that they have blown up tweeters and a blown up woofer. The midrange I suspect to be in fine working order as both of them are measured to 16 ohm.

     

    The tweeters I have gotten a hold of, the K-79(2-ti). But the woofer I'm not sure, and hoping for some expert advice.

     

    I have the KP-115 subwoofer, this sub have the K-48 woofer. The question is, can I use it as a spare for the one that's blown up? The woofer in the KI-362 is marked K-48-EP. Would it be possible to use the KP-115 K-48 woofer, and have the same perform as the original woofer and next to the working woofer?

    Hi

     

    I have recently bought two pairs of the KP-262. Haven’t heard or seen these speakers before and was hoping that some of you could have the specs, or even better a pdf spec sheet on them.

     

    Thanks in advanced.

    Heresy upgrade - what is this?

    Finally, here's my attempt to draw up the schematics, hope it's understandably. As I see it, the extra crossover can be removed quite simply, the question is what it's for? I just can't see why it's there. So I'm going to try and remove it and see if I can hear any difference, some day soon I hope..

    Heresy upgrade - what is this?

    in Technical/Restorations

    Hi, completely new to this forum, but have been reading on/off for years. Klipsch fan to the bone! (And from Norway, so pardon my some what pore english in advance.)

     

    I have just recently gotten hold on a pair of Heresy I in excellent condition, technical and cosmetic. I have hade the Forte II and Cornwall II before, both Crites upgrade. So I was wondering of do it to the Heresy as well, even tough they are 100%.

     

    But when I opened up the speakers i discovered that there is more to them. The speakers should be completely original, besides the backplate that has been changed. It had been changed for unknown reasons to the former owner, he had the speakers for seven years. But he had the original backplates with ID-stickers, so I got them in storage.

     

    To the point, I opened up the speakers by removing the backplates. Discover that the backplate i seriously heavy and filled with damping material, so the reason for change was a upgrade. Then I discovered that the crossover must have been modified as well, all the drivers and internal cabling seems original.

     

    My question is: Can some tell what kind of upgrade that has been done on this crossover, it looks like that it have ben added some more components to it.

     

    Thanks in advance for any help.
