The single handedly strongest, most powerful, most
bad assed subwoofers ever created in all existance of car audio, hands down, ever, by Cerwin
Vega.
The original Stroker line was designed to do 2 things only,
play extremely loud, and extremely low.
They weren't pretty, but looked tough, and played tougher. Most importantly, they would win and obliterate the competition in virtually any and all SPL contests they were entered in.
More recent lines of the Stroker have been upgraded with modern conviences. They are prettier, handle insane more amounts of power, and are probably bullet
proof!
On
top of still playing extremely loud and low, They will now also cause earthquakes; and will also perform kidney
stone lithotripsy.
I had kidney
stones, and couldn't afford to go to the dr to get the ultrasound
done to remove them. So I went to my buddies house and stood
next to his stroker at full blast. In the process I went deaf, and the neighbors house got leveled, but my kidney stones went bye bye.
