For free pickup in the Dallas , Tx area only (Plano specifically) .
This is a ported sonotube cab (i think about 134 L, tuned to 17 - 18Hz EBS ) I built for my adire shiva 12" MK IV (driver not for sale). About the size of an oil drum . Top and bottom endcaps are unfinished birch and the sonotube itself is covered with black carpetting. Worked VERY well for the past two years, but I need to clear some space.
Driver is top firing, port is bottom firing, so apart from some potential extra loading from the floor / sidewalls, there's no chance of anyone tossing beer bottles (or worse) into the sub

Please don't make me saw this up.
