here's a bump for you, i like these subs,. their great for daily, they get low, and hit hard. their also great for competition, i own 2 myself. these are very eficient, and can take a decent amount of power. they also put up very respectable numbers for sure. i have had the chance to play with a few top notch woofers, and i can say that these are at the top of my list for sure.
