polk audio boombox using 100 watt times 2 sure digital amp

I have a couple of Polk Audio bookshelf speakers that I'm trying to use with a new Onkyo TX-SR504 receiver. When I try to play a DVD or a CD after a while the speakers cut out.

Onkyo tech support said either my speaker wire or my speakers have a short. After trying new speaker wire, and connecting the speakers individually, the sound still cuts off after anywhere from 10 to 30 minutes. So, I guess the speakers have shorted...

I'm not very savvy with electricity or electronics. Just curious how the speakers may have short-circuited so I can avoid it in the future.

Also just seeking a second opinion. Does it sound like my speakers short-circuited? Onkyo tech support said if the receiver was the problem, I wouldn't hear any sound at all.

Thanks for any help.
Thanks all for your suggestions and ideas... can't believe how complicated this all is. But I will try to do some troubleshooting this weekend!

Thanks again.
thanks to everyone who gave their advice. it was *all* useful... going to be tough to pick a best answer.

As for the receiver, I've decided to return it and try a new one. Everything seems to point to the Onkyo, particularly after the heat, wiring, and other knowledge shared here.

Thanks again.

Perhaps someone can correct me if I am wrong but although it is common to experience a short circuit in speaker wire it is not very common to have a short circuit in the speakers themselves. A short circuit occurs in an audio system when positive and negative charges meet, interrupting the way the current was supposed to flow and causing an undesirably high current flow from the amplifier. This usually happens when the positive and negative wires touch at either speaker or amplifier terminals. It is possible for there to be a short circuit inside of a speaker but if this is the problem it can be repaired. I would check to make sure you have no exposed positive and negative wires touching (not even a little!). The Onkyo tech should have advised you as to how to isolate the problem. You should try some other speakers with the receiver and try the speakers on a different receiver. A possible source of your problem could be that the receiver cannot drive a 4 ohm load. Many Polk bookshelf speakers have a 4 ohm impedance. Eight ohms is the norm and the lower 4 ohm impedance causes the amplifier to work harder. Some receivers can only drive a 4 ohm speaker for a limited time before overheating and going into protect mode (no output). I would expect, however, your Onkyo to have no trouble with a pair of 4 ohm bookshelf speakers. As for the Onkyo tech...I am sure Onkyo has a very skilled staff, but I am also sure that standard procedure is to get customers to look at every other possible source of a problem before concluding the source of their problem is in the Onkyo product. Unless one of the experienced techs that sometimes answer questions here rules out the receiver as a possible source of trouble I would not assume that all is well with your receiver until you have checked to see if your speakers cause a similar problem with a different receiver.

You should try a stereo mini-plug 'Y' with RCA male ends, red and black usually. From these you can get extension RCA cables. Unless the speakers are self powered, you will need a small stereo power amp. They will have female jacks, plug in the 'Y's, and connect your speakers to the amp. Or, you can cut off the RCA jacks, strip the wires, attach directly to the speaker leads if they are powered.
All of the above parts can be found at your local radio shack. Banana plugs ARE an option, but wiring them properly can be a hassle. Limit amplification to 100 watts peak.

I have 2 old Polk Audio bookshelf speakers and I want to get a center channel speaker for them.

Should I be buying Polk again?

Yes, you should.

example :polk audio has different frequency than kplisch.? how do i view this..somebody please educate me.thank you.

The human hearing frequency range is 20 hz to 20,000 hz, 20 Hz being the lowest we can hear and 20,000 as the upper limit. Technically speaking, a good speaker system can handle this frequency range with low noise and accurate sound (natural sounding, not the boomy and distorted mid bass you hear from those hip hop cars) that is close to what you hear when you are watching the musicians live.

To get to down to 20hz and very limited distortion, you need a good sub woofer. I have a Hsu Research sub , http://www.hsuresearch.com , that goes down to this level that I added to my tower speakers, even though they go down to around 35hz.

Most THX and home theater systems are set up with a powered sub woofer that covers say 25 hz to 80hz and they have bookshelf speakers that covers from 80hz to 20,000 hz. So for your comparison, you want to look at the specs to see if they run close to 20 hz to 20,000 hz. After that, the most important part is to go and listen to them and make sure that you like how they sound.
