1. SAFETY INSTRUCTIONS
When using Peecker Sound electro-acoustic loudspeaker system it is very
important to act in full compliance with safety regulations. Professional
electro-acoustic systems are capable of producing high sound pressure
levels and must therefore be used with caution. Hearing loss is cumulative
and can result from lengthy exposure to sound pressure levels above
90 dB. Never stand close to electro-acoustic speakers operating at high
volume.
When positioning systems on the floor, always check that the base is flat
and stable to ensure correct speaker installation. Do not stack speakers
up too high outdoors where the wind may cause the stack to become
unstable. Suspended systems must be installed by qualified, experienced
personnel.
2. GENERAL INFORMATION
The Forty Series consists of 7 acoustic speakers (of which two are
subwoofers), including the active models with on-board DSP (24-bit, 96
kHz). The table below summarizes the main features of every model.

All the speakers are extremely compact and have birch plywood cabinets.
They are easy to transport due to their ergonomic dimensions and are
easy to install thanks to a carefully designed rigging system and dual-tilt
pole mount.
The construction design of the cabinet is optimized to minimize stationary
waves inside the speaker and to facilitate use of side-by-side systems. Every
part of the cabinet has been additionally reinforced to minimize internal
structural vibrations. As a finishing treatment, all loudspeaker cabinets are
also given a special coating for high working performance.
The components used in the Forty Series are the very best and most
technologically advanced that the electro-acoustic transducers market
can offer today. They include:
• Highly reliable lightweight Neodymium woofers;
• Tweeters made with Aluminium coils and Mylar membrane providing
perfect balance of mid-high range frequencies;
• Effective tweeter protections preventing drastic clipping, for perfect
control of transient response;

CONTROLLED RADIATION
• A.W.S.H.™ (Acoustic Wave Shaped Horn): Aluminium horn, designed to
completely rephase the acoustic wave guide in relation to the woofer;
• Minimum phase rotation crossovers, equipped with copper coils and
Kapton formers containing Ferrite powder, suitable for continuous use at
maximum power.
The directivity of Forty Series loudspeaker systems is perfectly controlled
and the frequency response is very wide and remains constant even out of
alignment, ensuring uniform coverage of the audience area.
The utmost attention to detail is shown throughout, down to the choice
of 15/10 impact-resistant grilles with 70% transparency, providing absolute
purity of sound.
The subwoofers are band-pass and the loudspeaker transducer radiation in
them is not direct but through two resonating cavities, one at the front and
one at the rear. This achieves highly efficient and exclusive reproduction of
ultra-low frequencies, without interfering with the other components of
the audio system. Thanks to its particular configuration, the loudspeaker
membrane is subject to far less movement compared to traditional reflex
systems, consequently distortion is considerably reduced even at maximum
power.
To complete the Forty range, amplified versions of some of the models are
available. Active speakers are perfectly integrated systems: the extremely
lightweight digital amplifiers have been designed to drive electro-acoustic
transducers efficiently and effectively, guaranteeing highly reliable and stress-
free products.
3. ACOUSTIC WAVE SHAPED HORN™
The Aluminium AWSH™ (Acoustic Wave Shaped Horn) has been designed and
manufactured using CAE tools (Computer Aided Engineering) to secure the
alignment between the acoustic centre and woofer while perfectly matching
the planes of the woofer cones and of the horn itself.
The manufacturing process is by die casting, which involves pouring the
molten metal alloy into a permanent metallic mold, or die, specifically
designed for this original product upon specifications provided by Peecker
Sound engineers. Forcing the molten metal under pressure allows very rapid
filling of the mold cavity and produces metal compensation to prevent
solidification shrinkage. This results in perfect and complete filling of the mold,
creating an end product with a fine, crystalline, flawless structure.
4. NUMBER OF SUBWOOFERS
Subwoofer models (40SW15, 40SW18 and 40SW15/A, 40SW18/A active
versions) in bandpass configuration have been physically and acoustically
designed to achieve maximum performance - hence the peak power
developed - at around 70 Hz. They are therefore compact and "fast" subwoofers,
designed to achieve a high output/dimension ratio.
Every model is easy to stack with other units of the same model to create
vertical subwoofer clusters, or with the associated satellite unit.
The number of subwoofers to be used mainly depends on the following three
parameters:
1) Number of 4008, 4010MH, 4012MH, 4015MH and 4030MH units
The recommended standard number of 40SW15 or 40SW18 subwoofers is
by a ratio of 1:1. Choose subwoofers 40SW15 in case of presence of 4008,
4010MH or 4012MH models and subwoofer 40SW18 in case of 4015MH or
4030MH models.
2) Type of sound program to be reproduced
The recommended standard subwoofer ratios are suitable for reproducing
classical music or for conventions. For these applications, the subwoofers
are an extension of the basic systems. In this case, the audio system works in
bandpass with three-way extension in bi-amplification.
For live applications with rock or disco music reproduction, a configuration
with a satellite unit/subwoofer ratio of 1:2 can be applied.
3) Type of location or installation
A 1:2 ratio can be applied outdoors, while a 1:1 ratio is enough to be applied
indoors thanks to the contribution of the venue.
