Certainly not a Sundown but mine performed well and have great low end if boxed correctly, legit power handling as well. I loved mine and I was very abusive to mine... killed em for a year and a half and sold nice stiff, basically new subs to the next guy... they work pretty good in 2ft3 net ported.Recommended by a buddy, the Skar EVL-12?
Good budget subs ... lower mid level ones
