Recommended power amplifier 200 to 500 watts @ 8 Ohms. The  Nexo PS8 R2 loudspeaker, can be used with LS400 sub as a system, great sound & very high quality.

The PS8 Loudspeaker features advanced NEXO designed low magnetic emission Neodymium drivers, making the PS8 extremely light and compact while usable next to magnetically-sensitive professional video or computer equipment. The dispersion, architecture and weight balance of the PS8 Loudspeaker are designed to provide exceptional PA/stage monitor performance from a single product without compromise. Background and foreground music playback applications are equally well-served by the PS8 system.

This flexibility is realized by a proprietary constant directivity asymmetrical dispersion horn, easily configurable (by users)in four positions by 90° rotations. 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 PS8's 2- way passive 8Ω design emplopys a single amplifier channel to deliver bi-amped performance for less money, space and complexity. The PS8 Loudspeaker System is the smallest member of NEXO's acclaimed PS Series. Versatile and compact, while offering full-range output, PS8 loudspeakers are tailored for a wide range of touring and fixed sound reinforcement applications. Like all NEXO products, the PS8 Loudspeaker, and optional LS400 Subwoofer, are designed to work with advanced electronic processors, guaranteeing the highest standards of consistent performance and reliability.

SYSTEM OPERATIONS
Electronic Controller	The PS8 TDController is precisely matched to the PS8 & LS400 cabinets and includes sophisticated protection systems. Using PS8 & LS400 without a properly connected PS8TD will result in poor sound quality and can damage the components. PS8 & LS400 can also be used with NXAMP4x1 and NXAMP4x4 Powered TDControllers.
Dispersion configuration	After dismounting the front grille from its fixings, the HF Horn can be rotated in 4 positions for dispersion configuration.
Sub-bass	The PS8 can be used without optional LS400 Sub-bass. Active two-way operation with the LS400 is included in the PS8TD. One LS400 matches 2 x PS8, additional LS400 may be used for enhanced LF capability.
Speaker Cables	PS8 are wired 2- & 2+ on Speakon connectors, LS400 on 1- & 1+. Loop through Speakons are present on both. Single identical cables can thus be used to loop through combinations of up to 2 x PS8 & 1 x LS400 in no particular order

[a] Response curves & data : Anechoic Far Field for the PS8 + PS8TD. Half-Space Anechoic radiation for the LS400 + PS8TD.
[b] Sensitivity & Peak SPL data : these will depend on spectral distribution and crest factor of program material. Measured with band limited Pink Noise. Nominal refers to Voice Decade (300 Hz - 3 kHz), Wideband to the specified ±3dB range. Data are for speaker + processor + recommended amplifier combinations. Peak SPL is at clipping of recommended amplifier.
[c] Directivity curves & data : obtained by computer treatment on off axis response curves.
