The Massive Audio Mega Subwoofer “RHINO” is simply MASSIVE! All “RHINO” Woofers are all skillfully hand assembled and use only the best components. The “RHINO” uses a reinforced pressed paper cone with hand stitched triple layer surround. Pure 14 gauge Copper Speaker Wire is then hard wired (no terminals) to a Quad 1 Ohm 4 Inch Voice Coil that’s bolted down with “three” Nomax spiders. A surgically cut custom aluminum basket holds the “RHINO” in place and can take up to 10,000 Watts of power. Crated in a custom birch box and weighing in at over 112lb pounds the Massive Audio “RHINO” is truly a beast!
