Sound

Delivers low-frequency sound with good clarity.

Offers great value considering performance.

Can deliver clear sound, but may also be overly loud and boomy.

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.

[This review was collected as part of a promotion.] This subwoofer worked great with my Blaupunkt 1500 watt amp. Good bass response, and I got it at a good price.

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

THUMP

Bought this about two years ago beat the crap out of it and it still hits hard!!!!

[This review was collected as part of a promotion.] Very nice subwoofer!!! Love the bass it pumps out. Not over done. Just right for a daily driver.

Works for me!!!

[This review was collected as part of a promotion.] Can't beat the price..  Good starter system.. Sounds good.. 2 on  1k watt amp..

[This review was collected as part of a promotion.] Wish it came with the harness and other pieces otherwise I love this
