Genelec 3440 Smart IP Subwoofer
Introduction
The Genelec 3440A Smart IP subwoofer is
a high performance subwoofer designed
to support Genelec's 4400 Series Smart
IP loudspeakers. It requires only one CAT
cable to connect, making installation easy.
The 3440A is powered using the standard
Power-over-Ethernet (PoE) technology,
using PoE+ or PoE standards. Using PoE+
is recommended for achieving the full
performance of the 3440A. The proprietary
internal power supply in 3440A delivers an
impressive short-term SPL.
The cabinet is made from MDF with
rounded corners and hardwearing textured
surface. The driver is concealed inside
an efficiency boosting cavity, which also
protects it from physical damage. The driver
is specially front loaded to improve both the
passband eciency and stopband rejection.
Reflex ports are generously sized with
radiused exits to prevent air chung noises.
The 3440A supports Genelec Smart IP
technology, which provides scalable power,
audio, and loudspeaker configuration.
Supervision and calibration features are
accessed via a standard CAT cable, oering
integrators unrivalled power, exibility, cost
eectiveness, and simplicity of installation.
The 3440A has been designed for excellent
sound quality over a very long lifetime. The
3340A is manufactured using certified
sustainable methods, and all essential parts
of the subwoofer can be recycled.
The 3440A subwoofer contains
• A highly ecient dedicated Class D power
amplier
• Switched-mode power supply technology
oering high SPL output using standard
PoE+ and PoE power supply with an IP
switch or power injector
• Electronic system protection
• Audio-over-IP streaming input
• Balanced analogue line input
• Flexible room acoustic compensation tool
set built in
• A cavity over the driver boosts the driver's
efficiency and acoustically attenuates
possible distortion components
The 3440A is designed for indoor use
in temperatures 15-35 Celsius and non-
condencing humidity
Unpacking
A Genelec 3440A package includes the
following items. Check that nothing is
missing or damaged in transit. If there is a
problem with the product, contact your local
Genelec dealer.
• 3440A subwoofer
• Euroblock connector for analogue audio
(conncted to the subwoofer)
Installation
When placed on the oor, the 3440A can
be placed in an upright position (factory
default) or at on its side. If placed sideways,
the base pads must be removed from
the original threads and screwed into the
thread inserts on the connector panel side
to provide sucient clearing for the cables
and avoid scratching. Wall and ceiling
mounting is possible using a Genelec 3440-
400 bracket available as an accessory. In
all cases, there must be a a free space of
10 cm (4 in) in front of the reex ports and
all cabling must be routed so that there
is no tension or pinching. When mounted
on a wall or ceiling, the base pads can be
removed for a cleaner appearance.
Cabling
To get started, connect an Ethernet cable
from the PoE+ output in an IP switch to
Figure 1. Connector panel of the 3440A
To create a working system, you will need
the following:
• An IP switch with a PoE+ (802.3at) output
for the 3440A subwoofer or an IP switch
with no PoE support and a PoE+ power
injector
• CAT 5 or higher category Ethernet cable
with RJ45 connectors
• AES67 or Dante audio-over-IP stream
source
• For 3440A setup and configuration,
a computer running Windows 10 or
Windows 11 operating system
• Genelec Smart IP Manager software
• Dante Controller software. Additionally
you may use Director or DDM to control
and manage IP audio parameters
Figure 2 shows an example of powering
the 3440A with a PoE+ enabled IP switch.
With this method, the power budget
available for all outputs connected to the
IP switch must enable each 3440A to run
at full PoE+ power. For 4 loudspeakers,
the power supply must support 4 x PoE+
power level.
Figure 3 shows an example of powering
the 3440A with a PoE+ power injector.
This method enables the use of standard
non-PoE IP switches. Each power injector
must support full PoE+ power level into the
device.
How PoE Power
Management Works
The 3440A internal power supply stores
power for peak output. This enables the
output power to exceed the input power
for short durations (Figure 4). Music and
speech signals are dynamic. They contain
high peaks above the average level. These
peaks are supplied from the energy stored
in the subwoofer power supply. The power
supply has been dimensioned to work with
audio and speech signals, including highly
compressed wideband audio signals. The
duration of peak output is limited more
by the PoE supply and therefore Genelec
recommends the use of PoE+ supply. When
the audio signal demands more output
power than available at the PoE power
source, the amplifier scales down the
output audio level keeping the audio quality
excellent at all times.

better exible cable. When the balanced
line input is used the subwoofer must still
receive PoE power on the Ethernet cable.
