This 6-channel Fender Passport 300 PRO portable PA system takes its predecessor, the Passport PD-250, to the next level with 300W of power (up from 250), a sub-out jack for an external powered subwoofer, lighter weight (a full 12 pounds less than the PD-250), smaller overall dimensions, and phantom power. The redesigned speaker system features 2 plastic molded cabinets with an 8" woofer and 1.2" horn-loaded tweeter in each for better definition, and and a sub-out jack has been added for an external powered subwoofer. please visit our website at http://www.mahkotamusic.com
