Nexo PS15 Passive Speaker

The Nexo PS15 Loudspeaker can be safely driven with over 1000 Watts of amplifier power, yet it has a small volume and reduced weight. The dispersion, architecture and weight balance of the PS15 Loudspeaker are designed to provide both exceptional PA and stage monitor performance from a single product without compromise. This flexibility is realized by a proprietary constant directivity asymmetrical dispersion horn, easily rotated in four positions by the user. Coupled with the horn’s unique progressive horizontal (50°to 100°) and vertical (55°) dispersion, the most suitable pattern can be selected for vertical or horizontal PA usage or wedge monitoring.

The 2-way passive 8 Ohm design uses a single amplifier channel to deliver bi-amped performance for less money, space and complexity.

The PS15 Loudspeaker System is the most powerful member of Nexo’s acclaimed PS Series; versatile, compact, full-range loudspeakers tailored for a wide range of touring and installed sound reinforcement applications. Like all Nexo products, the PS15 Loudspeaker and optional PS15Bass and LS1200 Subwoofer are designed to work with advanced electronic processors, guaranteeing consistent performance and reliability of the highest standard.

Recommended Amplifiers 550 to 1200 Watts into 8 Ohms for 1 x PS15; 1000 to 1800 Watts into 4 Ohms for 2 x PS15 per channel
Electronic Controller The PS15 Loudspeaker must be used with a Nexo Controller (PS15 TD MkII analogue or NX241 digital). Use without a properly connected Controller will result in poor sound quality and may damage the components.
Dispersion configuration After removing the quick-release front grille, the HF Horn can be rotated to one of 4 positions for dispersion configuration.
Subbass The PS15 Loudspeaker can be used with or without the optional LS1200 Subwoofer. Active two-way operation with the LS1200 is included in the PS15TD MkII, or NX241.
Speaker Cables The PS15 is wired 2- & 2+ on Passive Input Speakon connectors, LS1200 on 1- & 1+. Loop through Speakons are present on both products. Single identical cables can thus be used to loop through combinations of Passive PS15 & LS1200 in no particular order.
