The EXL series subwoofers have massive power handling abilities! Choosing the right materials makes the difference! Aluminum frame, paper with fiber glass cones, and a foam edge are all the makings of an all powerful subwoofer. These can be purchased in either 2 ohm or 4 ohm dual voice coil configurations. At 2,000 RMS power, the EXL-XX comes in 12" and 15" sizes respectively in order to provide more standard options of modifications and installations for our serious competitors.
