I purchased a 15" black widow cab from Daddy's Junkie Music about a year ago and really haven't needed it much and basically haven't used it. The only time I used it is when I was jamming with some friends at high levels. I noticed a lot of hiss before but I chalked it up to the loudness, possibly bad speaker cables, and channel noise from my Nightbass. I recently fired it back up with different cables and the hiss is so loud it's miserable! It is still loud as can be it just sounds like wind blowing through a microphone! Was this thing broken when I got it? Am I a moron for not sending it back? Is there anything else it could be? I power it with a T-Max 210 combo which is crystal clear and has had no problems.
