Does the Job

I put my first sub in and didnt want anything special so i tried out this 12-inch and it provides a nice low end to my usual rock/alternative/electronic music. Its nothing super pumpin but a nice overall sub for those on a budget.

Great speakers! I'm using them on a pair of MTX home audio speakers that finally went out on me after years of Djing & abuse. The new ones are even better. You can't go wrong with these subs !!!

Had two of these in my 08 impala with a MTX 600w monoblock amp. Great subs, hits hard and sounds great, I have owned several different brands of subs over the years and MTX is by far my favorite

Spend a little more for something else

These subs have a very limited range, very limited power, and just are not worth it. Don't waste your time with this entry level sub, spend a little more a get something decent. Mine is melted already.
