Strengths: Looks, very cool looking sub. Sounds good and seems efficient.
Summary: I got an opportunity to hear this sub in a friends car and wow, what a nice sub for a 10. It was in a ported enclosure and running off around 600 watts. It got pretty loud i thought, and dropped very low(tuned pretty low), even at low volumes. Blended pretty good with the fromt for an SPL sub and hit hard. I'd love to hear a 12, but a pair of tens would probably be just as loud or louder. Great sub,i'm impressed.
