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.

Going Further

Martin Audio Ltd manufactures a wide range of loudspeakers, system controllers and

power amplifier. Visit our web-site at www.martin-audio.com for the latest product

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.
