The PJ-304 is a projection speaker designed for ceiling and wall installations. Considered in architectural design, it can blend in with lighting equipment. The supplied swivel bracket allows for flexible speaker angle adjustment. The PJ-304 is driven on both high-impedance (100 V and 70 V) and low-impedance (8 ?) lines. The input power (impedance) can be easily changed at the upper side of the speaker. The speaker is easy to repaint so as to meet a wide range of design needs.
