    Default Please tell me my speakers aren't destroyed

    I've had RTI A7s for about a year now, run by a Yamaha RX A810. I also recently added a CSI A6 and FXI A6 rears. The system was never very loud at all so I finally caved in and bought an Emotiva XPA 5. I hooked it all up, starting playing some music I'm familiar with, and noticed no difference in sound, either in terms of volume or sound quality. I turned it up a bit, and suddenly lost all power. Now the woofers put out no sound at all. The tweeters are seemingly fine(hard to know for sure since I'm used to hearing them with woofers) and the center and rears are fine.
    Please tell me I'm an idiot and there's an easy fix for this. Like a fuse to change or something? I've never taken apart speakers before but I've taken apart other things so I can fix things if necessary.
    It just seems so odd to me that all the woofers would go at exactly the same moment, in exactly the same way. Please help, I can't be without music like this!

    Did your connector plates on the back of the speakers (the metal plate between the two sets of terminals) come off? If both towers went at the same time, I wouldn't think that'd be it, but its worth checking.

    The midrange drivers are working too. Just the woofers gone. Just to point out too, I do have a powered sub taking the load off the RTI's woofers.

    I have same setup as you without the Emotiva. I'd try un-hooking the Emotiva and try again. It also doesn't make any since you say it wasn't loud enough, I can only stand mine at -26, normal at -36.

    I unhooked from the Emotiva and put everything back the way it was. No change. All 4 woofers just do nothing whatsoever.

    Ok, do you happen to have another Receiver. If so just hook up the fronts and see what you get out of them.

    Unfortunately I don't have another receiver or anything else to hook up to the speakers. And I live in the middle of nowhere, with nobody nearby to even borrow from.

    Ok, Hookup two other speakers to the fronts and see what you get. If they work somethings happened to your 7's if not then it's the 810.

    OK I hooked up my rear surrounds (FXI A6s) in the front positions, and they sound normal. I also tried the center channel as the left front, and it sounded normal. But both of these only have tweeters and midrange drivers, not woofers, if that makes any difference.
    So if I need new woofers, as it appears, is this something I can get from Polk(or wherever else)? And what kind of $ am I looking at?

    And the Emo hater train is workin' up to full steam yet again!

    (As I own 2 Emos, I am offended and hurt about all this hate...so much so that I am going to go listen to my music right now and wallow in self loathing!)

    LOL!

    Anyway, OP, with the RTIs unplugged, I would gently push on the woofers and make sure the voice coil isn't seized. It should move relatively freely with no scratching noises coming from the speaker. I HIGHLY doubt you had an over-excursion event on all 4 woofers at once while listening at moderate volume.
    But best to eliminate that possibility.

    Thanks for the advice ZLTFUL. Could you please explain to me exactly what it is I'm feeling for when I attempt your suggestion? Also, to be fair I was a bit above moderate volume. Not crazy levels or anything, but more than moderate.

    g42 It sound like your Yamaha amp setting is not set correctly..
    Don't worry it was not the XPA-5 that caused this, unless of course you left everything powered on when you hooked everything back up..lol
    Go into your settings in the Yamaha and change your amp to 7.1 or another setting..
    Something like that happened to me and I eventually found out it was the Yamaha amp setting..
    my main speakers sounded all muffled but surrounds played fine..
    Something similar happened to me when I borrowed my friends Rotel amp, something in the Yamaha amp setting changed.

    Judging by your original post, I want to say you may never have set up the receiver correctly. Just for giggles, take the subwoofer out of the mix. Just hook up the 7's and set the fronts to large in the receiver settings, and speaker levels set to 0 for both. Play a cd and see if you get some sound. Woofers are pretty hard to blow especially since you had a subwoofer in the mix. The chances of a mid woofer blowing on both speakers....you'd have had to crank that puppy pretty good.

    Also, the fact that you said adding the Emo amp made no difference tells me you may not have connected it properly. If you can give us some details on how everything is connected maybe we can spot a problem.

    Just that the woofers actually move in and out and aren't making any noises like scratches when doing so.
    As stated, you would have had to REALLY overpowered them to get them to seize but I have heard of stranger things.

    I definitely tend to agree with the other sentiments that you may not have had things set up initially correctly.

    Agree with other posters, the chance that you blew all those woofers at once is miniscule. Check the settings first and then look at how you have everything connected.

    AVR's can be a bit confusing on the initial set up, and then when you're fooling around it's easy to change something and not realize you've done it.

    It would seem rather unlikely that all 4 drivers in both speakers are blown. Altho anything can happen. It would seem more like the 810 has gone nuts on the settings. You can try messing with them, with all your equipment still connected. If that dose not work, then you should disconnect everything, start from scratch. Only connect the 7's and a CD player....make sure of course your fronts are set to large. If that works, then you can plug back stuff 1 at a time, to make sure it all works.



    If that still dose not work, since you have no other receiver to try out on the speakers, it's time to pull one of the drivers out. If you have a meter, you can test it. If you don't have a meter. You can just take a 9 volt battery, just touch it to the terminals on the driver. If the driver is not blown, it will move the cone, either in or out depending on how you connect the + and minus terminals.

    If the driver moves, it's not blown.



    At that point, it's more then likely the 810. Since you don't have anything else to hook up to the speakers, that's not 100% guaranteed. You could..if you wanted to, go down to best buy, pick up a cheap stereo receiver that you can return the next day. If the 7's work fine, then you know 100% it's the 810.

    Going back to OP's original post, you stated you lost all power?
    The question is did one of your components, or more go into protection mode or did sound quit being produced from one or more speakers?

    As Tony said above you can check the speakers at full range. Put a CD in and push Pure Direct on the remote. That will give you full range on the fronts with no sub.
