    • Solid value and smooth bass
Size: 8" Style: Dual 4 Ohm
Solid subwoofer for the value so far. Does well as a replacement in a Polk box with amplifier.

    • Hard hitter
Size: 10" Style: Dual 4 Ohm
Sub works awesome, have it hooked up to a 3500 watt amp and it sounds great, hits the lows better than highs but overall a solid subwoofer.

    • Strong reliable speakers and give you way more than your money's worth
Size: 10" Style: Dual 4 Ohm
One of the best speakers I ever bought Baseline on this hit hard and I got it for my Kei van and if you guys know about those vans or trucks there's not a lot of room because of how small they are so I have a hundred Watt amp and let me say when this thing plays you would think that it was playing on a stronger amp and the way it sounded so clean and so pristine that people stop me and ask me what kind of speakers you got in there and I show them they're like I don't even know this brand but it sounds good I'm like yeah I would buy from them again love it ... show more

    • Very good sub.
Size: 10" Style: Dual 4 Ohm
This sub is good for the price. If you're good at tuning, and you have a bass knob then you can make this thing bump.

    • Good
Size: 8" Style: Dual 4 Ohm
Sounds great and nice little punch to it, I have it in a 1 cubic ft ported box with a JL Audio JX200 and it works perfectly, i can smell the glue heating up but doesn’t have distortion, for its size and price this 8 inch is a real budget bang for your buck

    • Good value and high quality.
Size: 8" Style: Dual 4 Ohm
I wanted an affordable sub that I could make a 2 ohm overall load for a cheap Bluetooth boom box amp. I parallel wired the voice coils and let it rip. Does it rattle the windows out of the house? No. Does it handle all the limited amount of power I've thrown at it so far? Absolutely (supposedly 350 watts). If you're making a portable ghetto blaster and want a little bit of thump to it, this thing will work well. It takes some power to get it moving so don't have too high of expectations if you're giving it low wattage. Some of those amps don't seem to really drive the sub channel until like 1/2 power and up. ... show more

    • Its okay as long as its in a regular cab truck
Size: 8" Style: Dual 4 Ohm
Its alright works as it should but if ur a bass head definitely dont go smaller than a 12". The 8" is not much better than putting better door speakers in ur truck. As far as for a car unless its going in the chenter console, or somewhere in the cabin with you. Its useless.
