These affordable subwoofers are built with die-cast aluminum frames to ensure durability of the product. The Butyl Rubber surround provides a tone of bass that sounds superior to most others. The Polypropylene woofer cone provides the loudest and highest quality punch on every note.

This is a great speaker, I have them in all my vehicles and for the cost of the speakers, you can't beat the sound, really deep bass without the boom, and the clarity is so good, very good speaker.

I run 2 of these in a .6 cubic foot vented box, and all I can say is perfect. The highs are unbelievable for subwoofers, and the lows aren't too shabby either. Still shakes the car at 30hz frequencies in the vented box. I love these little things.

These speakers are awesome to be so small. This 8" is packing a lot of bass and bottom. This is an awesome item to purchase even if its simple or an outrageous install.
