I built a infinity simple 12 using Dayton HPSA1000-R 1000W Rackmount Subwoofer Amplifier to power it. it sounded great until while watch transformers during the scene with the scorpion attack their was a loud pop then rigor set in. the amp says it has a built in 18hz subsonic filter i know 20hz was recommended. was the 18hz to low? im going to replace the woofer but would like to keep this one is their another woofer that would work in this box? i know it was designed for the infinity but just wanted to check my options. any help would be appreciated.
