SKAR audio dual 15" subwoofer box - $175 (Lock Haven)
Subwoofer box custom made by SKAR audio 15" subs with 600 watts RMS power handling each. Very under rated. Slot ported for SQ/SPL setup, each sub has dual 2 ohm voice coils. Carpeting job on the box is not very good but the box is all MDF construction and very solid. Sounds great and hits VERY hard. Subs are in excellent condition and fully functional.
