    • Great subwoofer box with deep bass!
Size: Dual 10"
Review Image by Sandro jesus gonzales
This subwoofer box exceeded my expectations. It feels well built, fits perfectly, and delivers deep, powerful bass without distortion. Installation was simple, and it has made a huge difference in my car’s sound system. Excellent quality for the price, and I would definitely buy it again.

    • Fantastic little Subs.
Size: Dual 8"
Very nice little dual 8 setup, they sound fantastic, and can play low notes still quite well even compared to 12”s. Not as loud ofcourse but frequency response wise they do a fantastic job especially connected to a good quality Amp that also has a good playable frequency response. Good quality Woofers not a cheap low quality setup by any means. For setups 1,000 watts or less these are fantastic. Beyond that I don’t see these as being as efficient with sound output per watt. But that’s fine cause Rms wise these are more meant for 800-1,000 watts. Quality of bass is great. Responsive, tight bass, so long as you have a Good quality Amp driving them. Never cheap out on amps. ... show more

    • Good value - great bass!
Size: Single 10"
Surprised by the nice tight bass. Overall a great subwoofer for the money. I did this combined with the CT Sounds 700 amp in my WRX with factory Harmon Kardon system. This is replacing my stock subwoofer which has zero ability to create any hard hits. Techno tracks with solid hitting bass hit you nice and hard. More than you would expect from a single 10 inch sub. If you do not mind brand X products - this sub offers outstanding value for the money. The bass now hits hard enough that coins on the roof of the car will rattle. Additionally - it does not sound. like loose flubbery bass. Tighter than you would expect from a budget ported box. Construction is very nice. The subwoofer looks like it has a lot of extrusion capability. Cone is nice and stiff allegedly made of carbon fiber. ... show more

    • Proper tuning is most important.
Size: Dual 12"
Sounds amazing straight out of the box. Paired it with the CT1500.1d mon block amp. Set the gain and frequency and your good to go. I put this in a chevy suburban and it absolutely shakes the whole thing.

Well its pretty loud for a 10. Decent well rounded sound profile. So many subs available I cant say for certain if there is better for the price or overall durability. Its not super exspensive and it does sound pretty good overall. Paired with a 2000 watt amp aswell. Hooked to the rear speakers of a 2020 nissan maxima with bose system and it was great adition ... show more
