So I just got a Sunn 1200s (read 2000s) head, after scouring through these threads, and with the indirect consultation of @edbass, and I'm looking for a good cabinet. The 2x15 Sunn's seem to be rare as hen's teeth. Any recommendations? Also, the Sunn is overpowering my Bergantino 8ohm 1x12 cabinets attached in parallel, which are both rated at 350 watts a piece, but it seems like the Sunn is blowing them up - speaker over excursion (resulting in distortion) even with the volume at 2 on the Sunn. Is this abnormal? Speakers in the Berg's are in good shape - maybe just getting an enormous amount of low end...any ideas?
