Repairing a home theater speaker ?

[Zragnarok]

I bought 7-8 years ago a Pioneer VSX 24-TX with a kit of energy speakers. The kit kinda look like this one but they aren't exactly the same.

So when I watch a movie, I always have problem hearing the dialogues. I have to put my amp on a setting to hear them better but the sound isn't as good. Being tired of it, I decided to play with the settings of my amp in an attempt to make the sound better. When I made a crossover test, I realized that my center speaker would sound very differently compare the others. It seems to play a lot of bass but not much treble. I then switched my Left speaker with the center one and played the test again. What should happen happened, my center speaker play normally (because it's my left speaker) and the left one sound very bad. So I know the problem is not my amp but it's the speaker.

I checked and the warranty for my speakers is 5 years, so i'm out of luck on that. My questions are :

1. I'm pretty sure of the answer but should all of my speakers sounds the same or because it's a center speaker, it's normal for it to sound like that ?
2. Is it possible for me to repair it by changing one of the speakers in it (the twitter I think) or it's probably a more complex problem ?

Thanks :/

- If they're all from the same series, the center should be voice matched to the other speakers. Often, center speakers are exactly the opposite of what you're describing, since a lot of vocal frequencies are relatively high range. As you're suspecting, that's not the proper sound for your center.

- First, I'm assuming that this isn't the case or you would have mentioned it, but...if your center speaker is made to allow for biamping (has two sets of binding posts), then that can result in this sort of issue. My brothers bought an open-box Klipsch center that had that, but wound up missing one of the metal tabs to connect the two sets. Connect it to one, got the tweeter, to the other, got the woofers.

Otherwise...can you fix it? Maybe. It -could- be a wiring problem, in which case it'd just mean some soldering or whatnot. On the other hand, you may have a problem with a crossover, or a blown tweeter. A well-designed speaker will have a crossover designed for the particular speaker drivers used. Simply dropping in a tweeter of the same size probably won't result in quite the right sound. You'd want the same model. Likewise for a prebuilt crossover.

IMO, verify that it's not a wiring issue, then contact Energy. Even if they won't do it for free, they may either be able to sell you replacement parts, or offer service at a lower cost than buying an entirely new speaker. Or they may just have a good suggestion on a replacement.

Yeah there's only 1 set of binding post on it.

I could always open it to see inside if everything looks ok but i'd rather not for now. I should probably contact energy first like you said.
