Hi My AV set consists of Audes fronts (capable of 38Hz) and center, Eltax rears and a Marantz 5300 amp. When watching movies and a bassy sound is used I hear a sort of crackling coming from my front speakers. It only happens during a mid bass rather than low bass sound. I would like to get to the bottom of this. Has anyone else experianced this? Could it be due to a poor front end source (PS2)?
