I have a used pair of empty double 18 inch subwoofer speaker cabinets for sale.
They do have a lot of road wear and will need some TLC and repair, but are still in decent shape.
They come as is and with NO speakers. The speaker grills are included.
I only have one pictured here, but obviously have 2 cabinets.
Size = 48" H x 28" W x 25" D
