Discover the depth: SUB 500, SUB 300

Reaching new depths...

Do you know that feeling you get when you
experience a large symphony orchestra performing
live with large kettle drums? The goose-bumps on

your skin when you hear the thunderous sound-effects
in a movie? Precise, deep bass you can not only hear
but also feel throughout your body enhances the
emotional content of the experience. To feel as well as
hear, a high performance, "intelligent” subwoofer is an
absolute must for any advanced multi-channel
audio/video system.

But not all bass is truly deep bass. And positioning a
subwoofer is not quite as straightforward as often it is
thought to be. The notion that the placement of the
subwoofer is uncritical, and that bass can’t be
localized doesn’t really hold true, as correct positioning
and adjustment is crucial to achieving an optimized
overall performance.
Almost all subwoofers available today require multiple
trips back-and-forth to the subwoofer during setup and
tuning. Adjusting output level, phase-angle, cross-over
frequency - even to a minor degree - requires having to
go to the subwoofer again and again until the right
balance is found. Making matters worse, adjusting one
parameter is likely to influence another, which in turn
will require further adjustments and so on.

The new Dynaudio Subwoofer Range.

The solution on offer with the Dynaudio SUB 300 and
SUB 500 subwoofers is far more intuitive. Both come

supplied with a remote control handset through which
all subwoofer parameter settings can be adjusted from
there where it matters most: the listening position.
Phase, level, cross-over point and extended frequency
range are all under direct fingertip control.

On top of this, four fully
programmable presets each
can store all parameter
settings into the subwoofer
memory. This way, it is easy
to switch from settings
ideally suited to a subtle
music concert to those
more tailored to a gut­wrenching action movie.
Recording engineers handle
sub-bass in quite a different

manner between these
genres, requiring different settings for optimizing the
playback of each. The presets can also be used to suit
a particular listening scenario, e.g. to remain civil with
the neighbors, one could also program in a preset
suited for late night listening!

New Features.

In addition to their highly practical adjustment capabi­lities, both subwoofers offer another remarkable and
unique feature: The Master/Slave function.

By incoporating multiple subwoofers, it is possible to
precisely balance out the unavoidable bass nodes one
would typically experience through utilizing a single
subwoofer. With multiple subs, even unconventional
positioning - such as close to a wall - poses no
problem. By using multiple subwoofers in a system,
an even and precise bass-response is easily achieved
without having to resort to expensive electronic room­correction systems or elaborate room treatment.

To facilitate a multiple-sub set-up, the SUB 500 and
SUB 300 each can be defined as "master” or "slave”.
A single cable connects each subwoofer to the next,
whereby all subwoofers in the daisy-chain will follow
the settings of the first subwoofer (Master) without
requiring individual adjustments themselves.

To achieve the phenomenal Dynaudio performance,
new woofer designs were developed for both
models. The SUB 300 thrusts its power through a

clever construction, combining a 10” driver in tandem
with a bass-reflex enclosure. The SUB 500 adds even
more punch, and guarantees impressive low-bass

response through its 12” driver housed in a sealed
enclosure. The new drivers feature extremely rigid
frames made of die-cast aluminum, geometrically
optimized for optimized air-flow. This detail is of great
significance, as energy otherwise reflected off the rear
of the frame would directly interfere with the precise
movement of the cone. The contradictory requirements
for an open-frame structure, yet one with high mechan­ical integrity , presented a true challenge - a challenge
readily overcome through Dynaudio’s vast engineering
prowess.

To drive the SUB 300 and SUB 500’s woofers, the
engineers developed a completely new proprietary
amplifier module which uses the advanced Dynaudio
CEC (Cone Excursion Control) technology. The CEC

circuitry takes all performance parameters of the drivers
into account, and continuously monitors the incoming
signal to derive the most efficient and optimum power
delivery. As a result, the Dynaudio SUB 300 and
SUB 500 subwoofers will play deeper, louder, while
delivering higher dynamic range and lower distortion
than subwoofers quoting much higher amplifier power
ratings. For long-term reliability, the electronics are
directly mounted to a massive heat-sink, which in turn
is integrated into the solid, resonance absorbing MDF
cabinet. Both single-ended RCA and fully balanced XLR
inputs are included.

Fusing the metal baffle with a layer of dampening material (1) to the furniture-grade finish cabinet (2) further
eliminates resonance, while both RCA and XLR in/outputs are found on its flexible back panel (3)

Coupling the driver to the cabinet follows Dynaudio’s
established design principle where a multi-layered
sandwich construction is employed: Fusing the thick,

stiff metal baffle to the MDF cabinet is a sheet of
special dampening material.
This construction effectively eliminates any unwanted
resonance and serves as the perfect foundation to opti­mize the fast and powerful transient signals from the
drivers. The result is an extremely precise and dynamic
transient response. The measures against resonance
are taken inside the cabinet as well: adding carefully
placed internal bracing provides the optimum balance
between low-resonance rigidity and intelligent use of
material.

Building upon Dynaudio’s fine tradition of craftsmans­hip, the cabinet itself is available in variety of furniture
grade finishes: With a choice of light Maple, traditional
Cherry, rich Rosewood, or stylish Black Ash, both the
SUB 300 and SUB 500 will easily integrate into any
room or décor. The subwoofer drivers may be hidden
from view by the elegantly sculpted black fabric grill,
which attaches to the metal baffle by use of tiny mag­nets – a functional solution with aesthetic appeal.
