I keep blowing the mids in my RTi 10's. I do not abuse the speakers and the system I have is very nice. It is a complete polk surround system and They are powered by a 100 watt plus per channel yamaha receiver. I am not reall happy with sound etc.. I was thinking it would be better. Any suggestions?

    Welcome to Club Polk
    I would strongly recommend a separate amp for those speakers. Using a receiver for speakers of that magnitude nearly demands a high currant amp. Don't get hung up on watts to much. Depending on which receiver you have you may have preouts for an easy amp upgrade.

    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks
    Ben

    well, it's not easy to blow a driver on speakers usually.. so yeah there is a good chance you should look into getting a two ch amp for yourself. hook that up and it should help. as mentioned above, most receivers don't have enough cajones to drive speakers properly, resulting in blown speaker drivers.

    I have an Adcom on the way for the same reason!
    So, are you willing to put forth a little effort or are you happy sitting in your skeptical poo pile?

    I agree with ^^. It sounds like you are pushing the receiver to hard so it clips or distorts and that will damage speakers more than too much power. Not sure what volume levels you listen to but with 5 or more speakers being driven at the same time it might happen at lower levels than you think it should.

    there you go..

    polrbehr, which Adcom are you getting? I have an older GFA 5400. it's powerful enough for my RT800i's.

    Funny that ben62670 and I replied in this thread, as I am getting his GFA555
    to power recently acquired RTi10s! They sound good with my Denon 2106,
    but I am hoping they will really open up with this Adcom.

    you keep blowing the mids... how many times have you had them replaced?

    If quality control with the Polk are not the issue, then others are spot-on. Get a quality separate amp to drive them. That Yamaha is probably putting out 1/4 of it's advertised wattage.

    I am looking at getting RTi8's. Will my Onkyo 502 receiver drive them okay, or am I going to have this problem too?

    I don't think the 8's are as power-hungry as the 10s (or 12s), but...
    Keep the volume level at or below insanity, and you will be good to go ;).

    I would like to suggest for you a Carver M-500t or a Carver M1.5t for those speakers. If you like it loud, get the M1.5t. If you want a very musical amp, go for the M-500t. These are vintage amps that pair quite nicely with those speakers. Many more suggestions could be made on newer amps, but I am not the guy to go to on that front.

    Or you might want to entertain the thought of a tube amp.

    Definitely separates. What is your budget?

    Your question may be answered better if you post this on your own thread. This way your subject will stay in focus and this gentleman's will as well. ;)

    True, but I didn't think it was likely that asking a related question would cause the thread to diverge. In fact nothing I do ever causes much attention. It's kind of my curse. But sorry to the OP for the intrusion.

    And thanks to the person who answered me. That's what I was hoping was the case.

    Is it both channels that the mids are becoming damaged, or is it the same channel over and over. Could be a problem with the internal speaker wiring, the terminals, or something you might not expect, with something getting rattled during use. The high current amp is a good suggestion for better power distribution. I have a Yamaha 7.1 setup as well, but its use is limited to being a preamp plus running the smaller surrounds. I use a power amp to drive the six 8 ohm Polk speakers I use as mains. Many are suggesting Adcoms, and I will attest to their durability. I've had mine since 1990 and it's still going strong. There are lots of good power amps to choose from, but you want to eliminate other causes just in case. Good luck.
