Unpowered 16 ohms line array speaker back panel features two combination input jacks that will accept either a speakon (twist lock) or 1/4-inch plug. These two input jacks are wired in parallel to provide a convenient way to daisy chain multiple speakers to a single amplifier channel. The LA4 features a pole mount socket on the bottom of the cabinet that fits a standard 1-3/8-inch speaker stand. This makes the LA4 a good choice for portable PA applications or for permanent mounting with certain wall mount brackets that employ the socket. LA4 is designed to take advantage of the unique sound dispersion characteristics of multiple stacked drivers.
