Sad they are not a package anymore!

This package sounded great. Nice deep, clean bass.


Although this no longer exist, it was by far my best ct purchase and it's the reason I got a lot of my friends to buy ct products. This packaged slammed so hard for the price, I had people constantly confused at how low the cost was. Good job Coleman, products like this let you feel the music.
