I sell a nice close subwoofer from SVS. It's the SB-16 ultra in black gloss finish.
There was just a small shock on the upper right corner which crushed a bit the corner, but it is not visible from the front.

With original box.

The ultimate reference standard for bass, SB16-Ultra redefines what is possible from a sealed cabinet subwoofer design with cost-no-object design and engineering.
