Introduction
Wavefront Compact Series Overview
Thank you for purchasing a Martin Audio Wavefront Compact Series system.
Wavefront Compact Series products make up a coherent "toolkit" of compact, live
sound enclosures covering a huge range of professional sound projects from high
quality club installations to major touring and festival systems.
Unpacking
Each Martin Audio loudspeaker is built to the highest standard and thoroughly
inspected before it leaves the factory. After unpacking the system, examine it
carefully for any signs of transit damage and inform your dealer if any such damage
is found. It is suggested that you retain the original packaging so that the system can
be repacked at a future date if necessary.
Please note that Martin Audio and its distributors cannot accept any responsibility for
damage to any returned product through the use of non-approved packaging.

About this Applications Guide
This Applications Guide is based on Wavefront Compact field experience and general
acoustical principles. We have provided information on the most popular system
configurations and have included simple equations for those wishing to calculate the
broadband coverage of their own cluster designs.

Cost effective rental
The Martin Audio Wavefront Compact Series "tool kit" approach provides all the
components required to assemble high quality, truck-friendly, quick deployment
sound systems for applications ranging from small clubs, commercial and theatrical
productions using floor placed W8Cs and W8CS’...
to vast outdoor events with flown Longthrow and W8C clusters:

Wavefront W8C systems are regularly used for audiences ranging from just a few
hundred jazz devotees to thousands of arena concert-goers. Longthrow sections can
increase touring system versatility even further and Longthrow/W8C combinations
have been very successfully used to cater for festival audiences from hundreds of
thousands to over two million at “Popestock” 2000.
The Wavefront Compact series includes both flown and floor-standing subwoofers.
W8CS’ may be flown where floor space is limited by extensive set designs or TV
camera tracks. Where floor space is available, Wavefront WSX folded horn
subwoofers may be used to implement an all-horn sound system for maximum
efficiency and projection.
Wavefront Compact system versatility satisfies rental companies' requirements to
maximise stock utilisation without compromising performance and reliability.
Wavefront W8C 3-way System
The heart of the Wavefront Compact series is the award-winning W8C (Section 1), a
compact, light weight, high performance, 3-way loudspeaker system that has been
engineered to work as well in small, stand-alone set-ups as it does in large flown
arrays.
A single Wavefront W8C cabinet will cover 55º horizontally x 30º vertically. The
W8C polar response is well defined so that it may be arrayed for high power rock
and dance applications in large venues. A smooth off-axis amplitude and phase
response allows a wide range of intercabinet angles to be used for easy coverage
tailoring.
All Wavefront Compact series cabinets are fitted with MAN load-certified flying
points to minimise set-up time. These MAN fittings are designed to comply with the
12:1 safety factor specified by the German VBG70 standard when used with
compatible MAN flying systems.

Wavefront Longthrow W8CT & W8CM Line Array System
The Wavefront Longthrow W8CT & W8CM system (Section 2) is a compact, very
powerful, light weight, multiple horn line array loudspeaker system whose cabinets
have the same footprint and flying points as Wavefront W8C and W8CS systems.
Unlike odd-ball line arrays from other manufacturers, W8CTs and W8CMs have been
designed to integrate seamlessly into the rest of the Wavefront family. The
W8CM/CT combination may be rigged in continuous columns for high power, very
long throw applications or may be used to complement regular W8C clusters by
providing spot coverage for difficult seating areas.
The W8CT combines three horn-loaded high-mid drivers with six horn-loaded high
frequency compression drivers. Like the award-winning W8C high-mid system,
W8CT high-mid cone systems are optimally loaded to produce much lower distortion
than typical waveguide-loaded compression drivers.
The W8CM has two vertically arrayed, low-mid horns to complement W8CT high-
mid/high systems with seamless amplitude and polar integration.
Like all Wavefront series trapezoidal products, W8CTs and W8CMs are fitted with
MAN load-certified flying points and are designed to comply with the 12:1 safety
factor specified by the German VBG70 standard.

Wavefront W8CS Flown Subwoofer
The W8CS (Section 3) is a compact, light weight subwoofer that has the same cabinet
footprint and flying points as the Wavefront W8C. It has been engineered to extend
the W8C's performance to below 45Hz.
The W8CS comprises a special high excursion driver coupled to an efficient mid-bass
horn and sub-bass port. This unique combination gives the W8CS the characteristic
punch of a horn-loaded system with the low frequency bass extension of a reflex
enclosure.
W8CS’ may be used as full bass subwoofers (up to120Hz) or may be flown as mid-
bass sections (60-160Hz) to complement floor standing WSXs.
Wavefront WSX Folded Horn Subwoofer
The WSX folded horn subwoofer (Section 4) complements Wavefront Compact W8C
touring systems to provide deep bass with maximum efficiency, speed and impact. It
has a classic Martin ‘S’ shaped folded horn and couples a powerful, high excursion
driver to the airload with a modified hyperbolic expansion law.
WSXs may be used as full bass subwoofers (up to120Hz) or as low-bass headroom
extenders to complement flown W8CS sections configured for mid-bass.

DX1 Loudspeaker Management System
The Martin Audio DX1 (Section 1.5) is a very high performance, 2 input/ 6 output
DSP-based controller providing crossover, protection, delay and alignment functions.
It comes with factory plug'n'play presets for a wide range of Martin Audio product
configurations including the Wavefront Compact family. It is ideal for combining
Wavefront Compact products into seamless systems.
For instance, two DX1s may be used to combine W8Cs, W8CS’ and WSXs to form a
stereo, 5-way, active, all horn system for the ultimate performance and impact. One
more DX1 may be used to add W8CT and W8CM Longthrow sections for difficult
venues or large outdoor events.
