Level 4 to XL SPL Spider/Voice Coil Upgrade Package

Level 4 to XL SPL Spider+Voice Coil Upgraded Re-cone

Money well spent. After multiple calls with DC tech wizard Justin I was able to make the informed decision to upgrade my lvl 4 m3 15 re-cone to the XL SPL option. It made a massive sound quality difference and has also allowed me to play the driver louder without sacrificing any of that sound quality. The only thing better than the quality and value of a DC Audio subwoofer is the quality and value of the technical support and customer service that come with it. High quality product from a high quality company. Thanks again Justin, your knowledge is invaluable

Strongly recommend. Will repurchased.

Great
