Here it is: the m3 version of the Lv5 subwoofer. Built for ground pounding and taking abuse in or out of the competition lanes. When we went to the drawing board with this one we were looking to make improvements in cooling: motor force and soft parts: With the AR surround / Cone: solid pole: machined cooling vents: 10” Spiders and a 3.5" coil we accomplished all of those things and then some. The end result is a sub that works great in the SPL lanes as well as Pounding out the LOWS!! To really step it up with this driver take a look at the Carbon Fiber options available for it.
