The XX series are the newest edition to a high-end woofer collection from RE Audio. This woofer borrows a lot the same features as the infamous XXX subwoofer, but for a much more affordable price!
The XX subwoofers use a dual composite 2-piece cone, and a rubber surround. They are housed in a cast aluminum basket and still use the 3” 8-Layer Aluminum Flat Wire Voice Coil that you find the flagship XXX. The XX woofers can be found in 12”, 15”, and 18” sizes, and both dual 2 ohm and dual 4 ohm configurations.
All of the XX subwoofers can handle 1500 watts of RMS power. The XX line-up shares many characteristics with the XXX. In fact, the main feature that separates the XX and the XXX is the magnet size. The XX woofers still use a very large magnet, however. What are you waiting for? Add some insane output to your vehicle today with a XX subwoofer from RE Audio
