Powerful active/passive speaker set with 12'' bass driver and 800W maximum power. Direct MP3 playback from USB sticks or SD cards. Sturdy MDF cabinets. The Fenton / Skytec SPB-12 speaker system consists of an active and a passive speaker to provide a rich and powerful sound. The Fenton / Skytec SPB-12 is ideal for medium-sized events, while the sturdy housing makes it ideal for mobile and even outdoor use. With a maximum 800W of power and a vigorous 12'' (30cm) bass driver, the master/slave Fenton SPB-12 speakers produce an impressive sound. The bass reflex design skillfully increases the sound pressure to give the bass the kick it needs. The SD and USB slots on the front of the speaker set allow MP3 files to be played directly from the appropriate media. Two microphone inputs make the Fenton SPB-12 ideal for vocal-centric events, such as in markets or at a karaoke party. The RCA line input also gives the option of connecting to other PA setups. The comparatively light but extremely sturdy MDF housing is easily transported thank to the top-mounted handles, while the dimensions allow the Fenton / Skytec SPB-12 to be stored in even a small car trunk.
