If you blow the subwoofer, there is a replacement cone kit that allows you to easily swap out the blown/burned voice coil and surround with a new one. The replacement kit allows you to keep the magnet and basket, therefore saving money as you do not need to buy a new sub.
Sonic Electronix offers quality products at very low prices. But not only that! With the purchase of my item they gave me a bonus gift, an accessory I would have had to buy in order to have everything working. And regarding customer service they were very quick in responding my questions.
