I have two of the 12''1244 version, same, same. I bought mine when they was on sale for 109.99, and that was the only reason, I never intended to run them this long, I just needed some cheep bass tell I got my blow through built, that was a year ago, my build plans have changed but the woofers are the same. I beat the SH&T out of them, running a RF T1500 @1ohm, it is know joke. watch Big D dino it @ old school. These are Vary, Vary, Good woofers even at the sellers price point. I have only smelled them after 45+ min full tilt. I seriously considered getting two more, running 4 of them in a 6th order blow through, but I would need dual 2's to run @1.
