LE Series

Compact, 2-way Stage Monitors


The stage monitor plays a key role in creating an onstage environment that connects performers to the audience. Martin Audio’s first LE monitor led the way to become the industry standard in the early 1970s, and LE monitors have continued to make their presence felt in the decades since.

Complementing Martin Audio’s state-of-the-art, high-performance XE Series monitors, the latest LE Series now brings engineering innovation to everyday stage monitoring —delivering exceptional performance and controlled coverage at a price point not previously possible for a truly professional monitor.



Both the LE100 and the LE200 are designed for a widerange of users and applications — from up-and-coming bands and regional rentalhouses, to corporate AV events, HoW and fixed installations. 

With extremely compact enclosures and unique CDD™ Coaxial DifferentialDispersion technology, the LE Series monitors deliver cut-through sound with acoverage pattern that allows performers greater freedom of movement compared toconventional monitors. Instead of the typical ‘hot-spot’, they produce anear-rectangular coverage pattern over a listening plane at head-height — witha wide horizontal coverage close to the monitor that reduces gradually asdistance increases to maintain consistent SPL and tonal balance.

Professional and affordable, the latest LE Series puts great sound,optimised coverage and the very latest in innovative monitor technologyliterally at your feet.


LE Series monitors feature Martin Audio’s unique,patented Coaxial Differential Dispersion drivers to deliver perfect monitorsound over a controlled area.

Coaxial Differential Dispersion technology combines the ‘point-source’benefits and compact format of coaxial designs with the consistent coverage ofDifferential Dispersion technology.


Non-coaxial two-way monitors can suffer from unevenfrequency response off-axis because the outputs of the LF and HF sectionsinterfere with each other, causing cancellations off-axis, depending on thelistening position. This is most noticeable close to the loudspeaker in theall-important crossover region — which lies right in the middle of the vocal band. 

In contrast, coaxial monitors can achieve ‘point-source’ summation ofthe LF and HF sections at all positions off-axis, even close-up. Otheradvantages of coaxial designs are that they remove the need for left andright-handed versions and are inherently more compact.

Up to now, a significant disadvantage ofconventional coaxial devices has been high frequency beaming — where the highfrequency dispersion reduces as the frequency increases. This is primarilybecause conventional coaxial devices channel high frequencies through a narrowtube in the pole-piece of the magnet system. LE Series coaxial drivers overcomethis by incorporating an innovative static waveguide that merges seamlesslywith the unique cone shape — maintaining the dispersion pattern out to very highfrequencies.

A Differential Dispersion horn has a 3D trapezoid dispersion pattern which distributes sound over a plane at the performer’s head-height more evenly than a system with a conventional,fixed-dispersion X° x Y° type horn, which produces an imperfect coverage pattern which misses out some areas — particularly side areas close to the monitor. 

LE Series monitors produce a well-definedcoverage pattern at head-height with wide horizontal coverage when standingvery close to the monitor. Further back, the dispersion progressively narrows,increasing the SPL to compensate for the increased distance from the monitor.The frequency response is unchanged, so the artist hears essentially the samesound balance and level wherever they stand within the coverage area. Thisconsistency in frequency response and SPL — both close to the monitor andfurther back — is exceptional.
