I will check my ports next time I play the sub loud.
I have noticed distortion coming from that area before. I thought it was either the driver over-extending itself or excessive port chuffing. I will focus on the port vents next time.
BTW, there is one demo that makes the LFM-1 go plum crazy in this regard, it's the 4th track from Kraftwerk's "Aerodynamik." Though I doubt you or the Outlaw team own it, I would love to know if it causes problems with other LFM-1s.
Very odd, considering it can handle bass tracks like U571 with relative ease.
