PowerPortPlus
PowerPort Plus is an enhancement in Power Port technology. Power Port Plus uses two ports (one front, one rear) and internal "plates" to further reduce air turbulence and increase bass efficiency. PPP allows even lower frequency tuning and lower turbulence for less noise and distortion, and more big musical bass, even at lifelike volume levels. This technology delivers performance that vastly exceeds conventionally ported speakers with bass that you truly feel, as well as hear. Learn more about PowerPort® Plus.
