I was listening to my Fi BL directly (head up against it) the other day and it sounds like its almost bottoming out only on high notes. Low notes sound great but its high notes that sound .. almost mechanical. I cant hear it in the car, and if i turn the gain down to where it doesnt make that noise, the sub barely moves.
I spoke to somebody local and their GPI sub does the same thing on high notes. Im trying to contac a person who owned an Fi BL and see ifthis is normal.
But for now, can anybody attest to this?
