This sub is cheap and hits hard, I bought this with a 1100 BOSS amp and I bought a ported box, this thing shakes my trunk like crazy and everything in my car and I usually only have the volume on my stereo at 20. It's a little bigger than 12in so cutting has to be done to the box to make it fit. But trust me, this thing is worth it and it's cheap, I plan on getting a second one

Bought these subs over the summer and installed them each in a small sealed enclosure (1.25 cubic feet). Definitely not the right size for these speakers because the bass starts to distort when I turn up the gain. I bet these subs will shine once I put them in an enclosure built to their specs.

Budgetary subwoofer. What is the average between the device for competitions on SPL and a qualitative sound. I have established it in a box with subwoofer in volume the recommended manufacturer. The box is collected from plywood of 18 millimetres of a thickness. Strengthened by partitions and glued on all joints. Frequency of a resonance has turned out about 35 hertz. The subwoofer works from the amplifier of monoblock Polk Audio 1200. Such decision has allowed to receive a loudness maximum level in 127 decibels. The windshield of my Focus at such loudness decently enough vibrates. As I apply this device not to competitions and for listening of music that I cut off the top border of a signal reproduced by it approximately on 70 hertz. As the head device (Kenwood XXV-01 - it is euro version) is equipped by the sound processor pleasant enough, musical sounding has turned out. Localisations of an arrangement of a subwoofer are not present.
In general this device completely justifies the put up money. Excuse me for my bad English. To difficultly enough inhabitant of Russia to describe a technical material on not a native language.

I got it for a early Christmas and I love it, it shakes everything and my amp is only at 900 watts right now. I'm going to soon put it at 1800 watts and get a second one, I love it. I recommend getting it. It's cheap and good quality. the only downside was I had to cut alittle more out of the box because it wouldn't fit into the 12in box.

i have two of these in a built to specs sealed enclosure and for a not so famous brand, these guys hit. i have each one powered separate by SSL 750 w monoblock @2ohms Approx 600 to 700 watts each and they rock. if i had a more brand name amp the guys would shine but awesome speakers anyhow for the price.

i just bought 2 of these i got a ma audio amp hooked up to them with about 400 rms on them in a ported box and they got great bass they still got a lot more to go . the designs and the price are great 2 get these they will suprize u. the only thing thats bad is the speakers to big for the box i have i had to put a saw to it and cut a about another half inch.
