PPI PRO FLAT PISTON 12" - used to rellll burn this sub...

..sounded real good though...but had to repair it bout 4 times by ratty opposite steves...first sub i ever owned
CERWIN VEGA VMAX 12" (ole skool one with the red ripple surround) - had an insanely high sensitivity 98db

got wayy louder than the ppi with same power and handled lows really well...i'd buy 10 of these if i can find them
2 KICKER L5 10's - box was made by balls and had curved PVC port like an elephant's tusk...they sound reallly loud for kicker's entry level square subs...1 of these 10's sounded more like a 12" back in those days...
ATOMIC ELE 15" - sub was fun as it was the biggest size sub i ever owned (i.e a 15") box made by miguel and used this sub to first enter car shows back in 2006...that was when shows were still at an average joe level...had a SS PCA1500d on it and used to win single 15" with it an ting
DD 9512 - was definately my favorite sub i ever owned that i used so far...got insanely loud for just a 12" and took sum crazy power handling despite the 1500rms rating..i'd recommend this sub to anyone wanting a monster 12"
T3 TSNS 12" - welll....only time will tell...i aint get to use it yet so when i do i'll update this post...
