I think for the price, this speaker is probably nearly as good as can be found. in fact, even at regular price (I got on sale) that it's good value. Dual voice coil and fairly light which is a plus if your doing spirited driving. I will likely get another one to pair with this one.

THUMP

I was looking for two subs for my truck, these are rated 800 watts RMS, let's just say the 750 Watt amp powering them makes them move me off my seat. They have THUMP. Ty

This subwoofer worked great with my Blaupunkt 1500 watt amp. Good bass response, and I got it at a good price.
