The Pioneer S-DJ80X 8" Active Reference DJ Speaker (Black) is optimized for use for DJ practice. It is composed of medium density fiberboard that houses a 8" woofer and 1" soft-dome tweeter. The speaker is capable of 160-watts of peak output and has a balanced XLR, balanced TRS and unbalanced RCA input, allowing for connection to a variety of audio sources. Its EQ controls are designed to allow you to adjust its output based on your preference. An auto standby mode assures power conservation by powering the speaker off when no input signal has been detected for 25 minutes.
