These SoundSplinter RL-P15 drivers are some monster XMAX beasts. With more than 24.6mm XMAX one way, these drivers move 3.96 liters of air each...I have 4. I am adding EQ to the sub with a Behringer Feedback Destroyer. The IB is powered by a Beheringer EP2500 Pro amplifier. Each driver should receive about 325 watts.
