Does anyone else who owns a 610hlf have this problem?: I bought my ampeg 610 cabinet a little under a year ago, along with a SVT-3pro amp. I've never ran more than a quarter of my amps power through the cabinet, but a lot of the time I notice that low tuned part of the cabinet (bottom 2 speakers) make a resonating sound. My band plays hardcore type music, and our gutairs are tuned drop C#. Could it be that the cab cannot handle the lows, and maybe look into adding a 15" cab to my 610s? I don't use a lot of bass in our songs...a lot of treble...with bass up half way on the EQ. Any thoughts...? Greatly appreciate it.
