The Nexo 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.

One LS400 is typically used with two PS8 loudspeakers, additional units may be used for an enhanced LF impact. The PS8 TDController’s integral sub section and combined signal (PS8 and LS400) Speakon wiring ensure cost-effective and simple system implementation.

Electronic Controller The LS400 Subwoofer must be used with a Nexo Controller (PS8 TD analogue, NX241 digital or PS8AMP integrated power amplifier).

Use without a properly connected Controller will result in poor sound quality and may damage the components.
Subbass The LS400 Subwoofer provides optional VLF extension for PS8 Loudspeakers. Active two-way
operation with the PS8 is included in the PS8TD, NX241 or PS8AMP. One LS400 matches 2 x
PS8, additional LS400 may be used for enhanced effect.

Speaker Cables The PS8 is wired 2- & 2+ on Speakon connectors, LS400 on 1- & 1+. Loop through Speakons
are present on both products. Single identical cables can thus be used to loop through
combinations of up to 2 x PS8 & 1 x LS400 in no particular order.
