SW218 and SW218+ are both vented design dual 18" subwoofers, SW218 is for indoor only and SW218+ is for both indoor and outdoor application, SW218 is rated for 1000 Watts while SW218+ is rated for 2400Watts. That's why SW218+ has 4 dB more output than SW218.

SW218 is constructed with High Density Fiber board, it is designed for KTV & all other indoor application, SW218 is about 2dB more sensitive than our competitors, with only 1600W input power SW218 could be as loud as other brand using 2400W.

SW218+ is a plus version of SW218, by using 4" coil and silicon treated spider, each 18" transducer could handle 1200Watts RMS power and without loose sensitivity, Our SW218+ is the killer in this price range, constructed with lightweight plywood, SW218+ will fit all appliction no matter indoor or outdoor.
