I have this sub in my car currently. It definitely is worth the money. I pumped 750 watts through that bad boy and it handled it like it was nothing. Puts out incredibly strong and deep bass and doesn't distort no matter what. I love mine, it has lived up to my expectations.

This is a really powerful little sub for the buck. I use this installed in a bandpass box in my hatchback, and this thing SLAPS like no other. perfect for small cars that aren't sturdy enough to withstand thousands of watts. overall clear bass, and great quality.

August 21, 2007 Good Sub

I had two Type-E 10 inch subs and stepped it up the the 12's. I have them running by a MTX Thunder TA4501 amp at 500 rms and they pound even harder than the 10's with a much lower frequency potential. So whatever you listen to these will please you and at a very low price.

My friend has two of these in a sealed box powered by an alpine amp, and let me say that they are the cleanest and loudest subwoofers you can find for your money!! Low cost, great sound. When I didn't know what kind of subs he had and after I listened to them he told me they were Type-E's, I was shocked. These babies really bang. I highly recomend them.

Customer Testimonial

I tried the Tech Support, my luck with this on many other sites is pretty hit or miss at best. To my surprise, I received a response in less than two days and it obviously showed that someone with some intelligence and knowledge actually carefully read what I wrote and made a reply that made sense.
