Delay systems for large scale outdoor sound reinforcement
The Martin Audio W8LM is a mini line array enclosure designed to bring line array performance benefits to a variety
of small and medium scale applications. It meets the need for a versatile, scalable system that can be flown or ground
stacked for corporate events, theatres and indoor venues. It is also suitable as a delay system for large scale outdoor
sound reinforcement.
Following the constant directivity horn design philosophy of the W8L and the W8LC, the W8LM is a three-way
system that combines line array principles with innovative horn loading techniques to produce a next generation,
small line array with maximum dynamic impact.
Amazingly for its size, the W8LM is a full-bandwidth system (-3dB @ 60Hz) and may be used without subwoofers
in many applications. Where additional low frequency extension is required, it is ideally complemented by ground
stacked WSX or WLX/WMX Hybrid™ folded horn/reflex loaded subs. Alternatively if flown sub-bass is required
then WLX/WMX Hybrid™ folded horn/reflex loaded subs may be used.
To achieve the vertical pattern required, practical line arrays are nearly always curved in the vertical plane –
invalidating some of the simplistic ideas about wavefront curvature associated with first generation line arrays. The
acoustic elements of the W8LM have been developed to have optimal wavefront curvature characteristics for real
world situations where higher degrees of array curvature are likely.
Whilst the W8LM is a three-way system, it can be driven two-way active or entirely passively via its internal
crossover, (selected by a rear mounted switch). To make system design even more cost effective, the W8LM is a 12
ohm cabinet and up to four cabinets can be driven off one channel of a professional quality amplifier such as the
MA2.8s or MA4.2s.
The minimum number of W8LM elements in an array is 3, but most applications will require blocks of 4, 8 or 12
elements, depending on the required output capability and
vertical coverage angle.

technical specifications (single enclosure)
architectural and engineering specifications
The loudspeaker system shall be of the three-way
horizontally formatted line array type, switchable
passive/bi-amp. The low and mid frequency sections shall
consist of two 8" (200mm) cone transducers, one direct
radiating and reflex loaded and one front loaded by a
constant directivity mid-horn using a toroidal phase plug
and reflex loaded, with both sharing the same enclosure.
The drivers shall operate in tandem to produce low
frequencies up to 300Hz. Above 300Hz, the direct
radiator driver shall be rolled off by an internal passive
network and the horn loaded driver reproduce mid
frequencies up to 2.2kHz. The high frequency section
shall consist of two 1" (25mm) horn elements vertically
mounted to produce a low-curvature vertical wavefront.
The enclosure shall be constructed of heavily braced
multi-laminate plywood with all flying hardware integral
and captive. Bi-amp or passive operation shall be selected
by a switch at the rear of the enclosure. In bi-amp mode
the loudspeaker shall be operated with a separate
electronic controller providing a 2.2kHz crossover
between mid and high frequencies. In passive mode the
mid and high frequency sections shall be integrated by an
internal 2.2kHz crossover network.
