If your customer wants the most boom for their buck, look no further than the Episode Element Ported, Powered Subwoofer. Available in 8", 10", or 12", this powerful little sub produces less port noise due to the even flow of air through its slot port design. Featuring a highly-efficient DRiVE Class-D amplifier, this sub is also 60% more efficient than conventional analog designs. Top it off with our signature LFEQ technology, and you get a sub with max bass performance for its modest enclosure size.
