I purchased this speaker & cabinet new about 4 years ago. Never gigged - only practice at home. The "Seismic" badge came off during a move. It could be easily re-attached, but I never bothered with it. I used this 2x10 paired with my 1x15 Eminence - Legend CA154 speaker (also for sale).
I acquired a small practice amp an no longer need either of these speakers.
