Not bad. Great for 70$ or less price point.

One of the best subs under 100$. For 60$ cant really beat it. Have it in a sealed box right now and it gets loud but it doesnt hit the lows at all. Then again, its in a sealed box. Im going to get a ported box to try with it soon. Fantastic woofer for the price.

Great Sub for the money!

I would highly recommend this Massive Audio ECO subwoofer. It sounds great in a ported box. It's louder than the 2 alpine bassline 12's in a foxbox in my 2005 Ram.
