SKU: LS400 Categories: , ,



The LS400 Sub-Bass extends the usable range of the PS8 Loudspeaker to 40Hz, providing high performance and high power output (131dB Peak) in an extremely compact, light weight package. The NEXO-designed shielded 12in Neodymium driver allows the LS400 to be used in close proximity to magnetically sensitive video equipment. Two LS400s are typically used with two PS8 loudspeakers, additional units may be used for an enhanced LF impact. PS8 and LS400 presets in the DTD Controller ensure cost-effective and simple system implementation while the NXAMP powered controller offers full network connectivity and the facility to combine PS8/LS400 configurations with any other Nexo cabinets.
