OK the simple solution is to turn it down LOL It seems one of the 6511 drivers sounds like its farting after a bad night of beer and white castle LOL Now this only happens when kicked hard. At softer normal volume it sounds fine. Do you think it just might be a coil rub? If so, is this fixable or does it need to be replaced? It is the right side, top inner 6511.

How did it pop? Sunfire sig 625x2 on the sda 2.3 at a nice concert volume. The music was Fleetwood Mac The Dance, opening kick drums on the chain. BTW if you are a fan and don't have that cd, the quality is great and sounds wonderful on the SDA's.

    Sounds like voice coil rub to me. I'd replace the driver and call it a day.

    I am going to bet the driver that pops is blown. When they go they act like little passive radiators that are over driven by the other drivers. Pull the suspected driver out and take an ohm reading.

    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

    Agreed. It's bad, buy a new one. Pull it out, take an ohm reading then throw it in the garbage.
