Axiom Home Page Forums General Discussion Technical Questions Hum from AX500A Axiom Subwoofer.

On your 350s does the hum come from the speaker or the amp? If it is from the amp itself, it could be transformer hum from harmonics in your electrical supply. There are sine wave regeneration products out there that may clean it up, but the cheaper ones use stepped sine approximations which may have just as much trouble. Of course since you can't hear it from any distance, you may just not care.
