    • this. thing. SLAMS.
Size: 12" Style: Dual 4 Ohm
this thing slams. i have the voice coils running in parallel, so 2 ohm load on the amp. in a ported box. running about 300W, and the people next to me at stop lights hate me, because it's shaking their mirrors. quite happy with this purchase.

    • Great little subwoofer
Size: 8" Style: Dual 2 Ohm
Sounds ok installed in the same place as a stock subwoofer in 2014 jeep grand cherokee. have a rockford fosgate r2-1200x hooked to it turned down though it holds the power just fine. plastic box stock is not the best though.

    • Le falta mejorar
Size: 8" Style: Dual 4 Ohm
Es bueno,con el paso del tiempo da un bajo o golpe delicioso, buena sensación de satisfacción en el oyente. Obviamente en una caja bien diseñada funciona bastante bien.

    • Great build quality and sound!
Size: 10" Style: Dual 2 Ohm
Review Image by Tyler Hagner Tyler Hagner
Great build quality and sound for a shallow mount 10in. I’m sure this thing really has a lot of potential in the right box but I had to use the smallest box I could find since I installed this in a Kenworth dump truck. I’ve owned multiple subs and never noticed a difference after a break in but this thing continues to get better with time. I listen to it pounding all day 10-12hrs a day powered by a ct sounds 400.1d compact amp with no issues. Will definitely buy agin for future projects. ... show more

    • CT Sounds Rocks
Size: 10" Style: Dual 2 Ohm
These 10s hit very hard combined with CT sounds 1500 watt amp...after the break-in they seem to push harder and harder...i would give 6 stars if I could

    • Ahem!!!!
Size: 10" Style: Dual 4 Ohm
Dont really know how to write this because I dont know terminology for subwoofer manufacturing but here goes. I've tried a multitude of subs. This is the first one that meets my sound. This sub right here nailed SQ. FOR MY setup. I am not willing to move mids out of doors. I am not wanting to put some mid bass pods somewhere. Stock locations and stealth for me. The most annoying thing about a sub is when you have bass or bass guitar, then kick drums and drums are busy, a lot of subs dont handle that well, dont spring back in time? Not sure the lingo but it Causes a very muddy transition. most folks just boom it up and hide it I guess. I cut the top off my subs at 145 at 24slope, probably unusual but the door component woofers simply cant get down there. I also like the sub to play boomy modern songs smoothly without needing a knob somewhere. I ask a lot of them and this thing does it. Dont ask me how or why. Couldnt tell you but I tried some pretty expensive subs that didnt do it because I'm running a weird box for stealth. I stared at the design of this sub and thought, well let me just try it. This IS THE SUB I'm keeping. 100 bucks. Cant hardly believe it. Oh, it also handled time alignment really really well. Some of the subs even at the same inches away in dsp didnt seem to move front seat as well. Again, not sure how or why each sub reacted differently. ... show more
