How can I tell if something is wrong with my mid range speakers on 2 rtia7s?

I recently blew out 2 tweeters on my rtia7s while trying to show off my system. Polk was good enough to send me 2 on warranty. After hooking up the new tweeters I noticed my mid range speakers sound like they have a bad equo to them. Are they blown or close to?

what are you running these with? Receiver or Amp?

I have a pioneer reliever the SC 1228. They are Bi amped

Bad equo?
Remove your crossovers and inspect them for burned parts.
Stop ghetto bi-amping your speakers.

It's a pretty bad equo yes. Is Bi aping not good or what? Where are the crossovers on the speakers?
-
OK are you also using a equalizer?

From your description it sounds as though you have damaged the mid range drivers and should contact Polk CS, in all likelihood they will replace them under warranty. F1nut's advice is correct, you should look at the components on the speaker's crossover. When you are talking to Polk ask them where the crossover is located. You'll want to look for any severely browned or blackened components or parts that look like they've exploded.

Instead of providing nice sinusoidal AC to your speakers, you provided close to square-wave DC (flat-topped sine-waves) to the speakers.
Dude doesn't understand bi-amping or where the crossovers are and you hit him with this? Hell, I don't even know what you're talking about...

I think you're trying to say equalization, which really isn't the right term. What you seem to have is a lack of balance between the highs and lows. Balance being the key word.Is Bi aping not good or what?
You'd have to ask the apes.
Bi-amping on the other hand is something much more involved than what you are trying to do with an AVR. Basically, you cannot bi-amp with an AVR no matter what any AVR company states. It's marketing hype, nothing more. You're much better off connecting a single run of high quality speaker cable and replacing the stock jumpers with the same high quality speaker cable.Where are the crossovers on the speakers?
On your speakers they are directly behind the binding post plate (where you hook up the speaker cable). There are 4 screws, remove them and carefully pull the assembly out. It will not come out very far, so do not try to force it out further.

I think he means echo.afterburnt wrote: »They didn't speak a word of English, they were from South Carolina.

Yes I do mean echo. Not equalization. The mids sound like they are in a big hollow room. So basically I need to check the cross overs. I need to get some good speaker wire. I need to stop by amping. I need to cool it on the volume. And last I probably need to replace the mids. I've never heard a damaged speaker sound like that before. I appreciate all your guys s help. Thank you
-
I don't think there's anything wrong with your drivers. What you are describing is the sound you'd get without the tweeters working. Since you have new tweeters that means the crossovers are damaged, likely a cooked resistor.
BTW, you need to get spell check.Political Correctness'.........defined

@Gstradeski - first, welcome to the Forum.
Polk Audio (Customer Service & this Forum) will get you up and running and enjoying those speakers before you know it.
Stick around, ask your questions, and you'll gain a lot of knowledge of everything audio. Your wallet may start to hate you after awhile though...
So, are you willing to put forth a little effort or are you happy sitting in your skeptical poo pile?

F1nut. You are right. My auto correct has gotten away on me a couple times. I never even noticed til you said something haha. So if what your saying is true how easy of a fix is that? Pitdog sorry I missed your comment earlier. I do not have them going through an equalizer
-
well that is ok I do not know how nightfall derived echo from that but he hit it. can you solder? if you can then its a piece of cake if you cannot then it just got more expensive. I'd follow F1's advice then get back, if you can take pictures to show us that would be much better. we'll go from there.

I don't know if this view of it will help.
-
Well twice I uploaded a picture of it and it didn't show up. Not sure what I'm doing wrong
-
I took the piece out from the back of the speaker. Nothing looks burnt or exploded to me

Look closely on the crossover board. Anything that looks out of whack, burnt, look under too.
Once a pic is loaded on your computer, click on that darkened page icon at the top here and browse your pics. Then simply click on it to add it to the thread.HT SYSTEM-
