Way better than a kicker comp 10!!

Good quality built subwoofer. Definitely better sound quality that my older kicker comp 10. One small thing I noticed is that it’s not quite as loud as the kicker comp in the same box and amp (same impedance and haven’t changed any settings). But that could be BC this sub is dual voice coil while the kicker wasn’t. This also has a bigger coil diameter in it (2” vs 1.²⁵⁄₁.5”).

GREAT

Amazing little powerhouse!!! Bought this one to try , now gotta buy another one because I’m fully impressed

CT Sounds an amazing subwoofer

I purchased this subwoofer to replace the blown Rockford Foscate subwoofer that was in my sons P300 box. The P300 is a popular box with a amp and crossover already built into the unit from Rockford Foscate. The first time the Rockford Foscate P300 broke Rockford Foscate sent me out a new unit. The new unit broke under nine months so instead of purchasing another unit I decided to fix whatever was broken. I knew it was either going to be the amplifier for the sub. When I figured out the sub had blown I called Rockford Foscate to see if I could purchase a new subwoofer. They said all I could do was buy another unit, I purchased 1 unit and they set me out a second unit and neither of them lasted 10 months. I did my research and found this speaker CT Sounds and it matched up with the specs needed for the replacement subwoofer. At a fourth of the price of purchasing a new unit I decided to experiment to see if the speaker would work. I bought a dual voice coil 12 inch sub 2 ohm and I dropped it down to a 1 ohm. And just like that the unit sounds amazing again. I’m sure glad I didn’t throw it out and spend $200 to $300 on a new unit. I love the sound of the speaker and I will for sure be purchasing more Products from CT Sounds in the future. Maybe Rockford Foscate should start purchasing their speakers from CT Sounds lol.

Great deep sounding Bass

Great deep sounding Bass, I bought the 2.0, instead of the 1.0 because of the rich bass it produced, when comparing them both on youtube reviews.

Very impressed great sound from a small little sub

Great sub for the price

These are by far the best sub under $100 period. Tight deep bass and true RMS ratings, I have mine running a little over the RMS so i don’t under power them i just take it easy…
