It was 955 watts(zx750.1) No voltage drops or anything when playing heavy gains set correctly with a dmm. The coil is scratchy and hard to press now so i figure its from thermal limits being reached to much. was in a sealed box so wasnt able to smell it when it had enough :/ Also at some point the surround came undone from the cone //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif. Was a great woofer and very sexy. Its just not a fan of that much power i guess. Time to move on to something else.
