Martin Audio LE1500S 2-Way passive bi-amp 15 inch monitor

Stage Monitors

Martin Audio introduced the first LE monitor, the LE200, in the 1970’s. Since then its successors, the LE400 and LE700 have become industry standards selling in their thousands and gracing the most prestigious stages for an unrivalled who’s who of artists.

The LE2100S, LE1500S and LE1200S stage monitors are capable of generating exceedingly high SPL’s with a minimum of distortion. They are housed in contemporary styled, camera friendly cabinets of lightweight, yet exceedingly robust construction and are eminently suitable for any reference situation.

Martin Audio has long been heralded for ground breaking horn design and the differential dispersion horns in the new LE Series continue that tradition. Differential dispersion horns allow high SPL’s and consistent coverage to be achieved without running into feedback or excessive spill problems. The performer is therefore, free to move over a wide area without hearing significant changes in frequency or SPL.



Martin Audio LE1500S

* 2-Way passive/bi-amp 15" monitor

* Active/passive, low profile, high power, differential dispersion stage monitor

The Martin Audio LE1500S is a compact, high performance stage monitor combining high output and controlled dispersion with discreet, contemporary design. It features a high–specification 15” (380mm) low frequency drive unit and a 1.4” (35mm) exit compression driver mounted on a differential dispersion horn. Differential dispersion technology increases the area over which a constant SPL and consistent frequency response is maintained at ear height, enabling the artist to move around more freely.

Driven actively, the LE1500S is best used with the DX1.5 controller to provide crossover, limiting and EQ functions. When operated in passive mode the LE1500S, may be used without a controller, but benefits from the EQ and limiting functions of the DX1.5. This also ensures that both active and passive configurations will exhibit the same tonal balance when used together on stage.
