DALI SPEKTOR
WHITEPAPER
INTRODUCTION
At DALI, we are deeply committed to bringing the
scintillating joy of true Hi-Fi sound to a wider audience.
Every speaker series we have developed since we
started more than 30 years ago has brought us closer
to this goal. Regardless if it was our high-end EPICON
series or the compact battery driven KATCH, we knew
that we were bringing Hi-Fi sound to new listeners.
With the brand new DALI SPEKTOR series we again break
new ground. The SPEKTOR series is an affordable Hi-Fi
speaker series that consist of four models. SPEKTOR 1,
SPEKTOR 2, SPEKTOR 6 and SPEKTOR VOKAL.
Bringing the SPEKTOR series to life has been a delicate
balancing act of getting the optimum amount of audio
performance, and optimising the production of every
element of the speaker. Getting this much Hi-Fi
performance from a speaker series in this price range
not only took all of our experience and know how,
but also hours and hours spent in the listening room,
improving the driver and crossover designs to create the
perfect audio performance.
The DALI SPEKTOR series brings the DALI sound design
principals to a new price bracket, opening the possibility
for many new music and movies lovers to experience the
seduction of true Hi-Fi.
We are very pleased to introduce the new and exciting
DALI SPEKTOR series.

PRODUCTS
The technological advances DALI has made over
the years, and the experience of not just designing
but building our own drivers in-house, has given us
the unique opportunity to launch a series of very
reasonably priced speakers that include several of
DALI’s core technologies, living up to the rigorous
standards we set for ourselves and our products.
The SPEKTOR series represents true DALI sound, real
Hi-Fi and a quality speaker series at a price range
where DALI has never been before. Four different
models complete the SPEKTOR series: Two compact
speakers for wall mounting, shelf or stand positioning,
a large floor standing speaker, and a centre channel to
complete any surround setup.

SPEKTOR 1
The ultra-compact speaker in the range. Built around a 4½”
wood fibre woofer and a 21 mm soft dome tweeter, the SPEKTOR
1 is perfect for almost any situation that requires a small but well
performing speaker. Front, rear or side speakers in a surround
system, or alone is a compact stereo setup.
SPEKTOR 2
Whilst still being a compact speaker, the SPEKTOR 2’s larger inner volume delivers extra
bass performance. The increased surface areas of the 5¼” woofer and 25 mm soft dome
tweeter increases the overall sound pressure levels, making this the perfect choice for
larger rooms that still require a compact speaker. The SPEKTOR 2 will also find itself at
home in any surround position, helping you get that fully immersive movie experience.

SPEKTOR 6
Built around two 6½”
woofers and a 25 mm soft
dome tweeter, this large
floor standing speaker is
the power-house of the
SPEKTOR family. Serving
up a detailed, dynamic
and powerful audio
reproduction, they are
the perfect choice for any
stereo or surround setup.
SPEKTOR VOKAL
Taking centre stage, the SPEKTOR VOKAL delivers clarity
and depth to any movie. The two 4½” woofers and 25
mm soft dome are setup to match perfectly with any of
the three models in the SPEKTOR series.

By creating a very linear environment the speakers presents
an amplifier friendly load.
Optimised drivers enable low
complicity in the crossover
ensuring low signal loss.
DALI SOUND FUNDAMENTAL
Wide dispersion creates a
uniform sound experience
in the entire room.
The primary function of any loudspeaker is to convert
the electrical signal from the amplifier into a realistic
audio experience in the listening room. Any distortion or
coloration of the original signal by drivers or enclosures
is by definition a degradation of the sound. At the same
time, the most important function of a loudspeaker
is to secure a musical, informative and entertaining
experience for the listener in their own home.
The DALI SPEKTOR series, like all DALI loudspeakers,
has been designed in accordance with our fundamental
acoustic and electro-acoustic principles, and a strong
belief that clarity and an authentic, honest sound
reproduction will get you even closer to the full impact of
a live music experience.
Clarity in an audio signal is obtained by low loss of
information in combination with creating a smooth and
seamless reproduction in both the time and frequency
domain. To retain such seamlessness, the integration of
the drivers in the loudspeaker is paramount. The success
of integrating two “overlapping” drivers is dependent on
numerous combinations of elements, which can only be
achieved by carefully optimising the driver for not just
perfect frequency response in its main working area, but
also at its outer limits. This attention to the roll-off area
is one of the key points to a seamless experience.
By using only DALI designed and custom-built drivers,
the need for frequency correction in the crossover
is eliminated. This enables us to design an exact
crossover which together with carefully selected quality
components ensures that the signal loss is close to zero.
Another fundamental is the lowering of mechanical
distortion, since mechanical distortion will introduce
un-linearity into a loudspeaker system. An un-linear nonstable environment presents the connected amplifier
with a larger than necessary challenge, causing loss
of detail in the signal even before it has the chance to
reach the loudspeaker.
Through very low mechanical loss, the most fragile
sound details, even at very low listening levels, are
preserved. This is the only way to obtain the sensation of
ultimate transparency and “liveliness” from reproduced
loudspeaker sound.
Every element of the SPEKTOR
speaker is meticulously
designed to conform with the
DALI sound fundamentals.
Optimizing the audio signal for off-axis distribution
results in the signal reaching your ear directly and the
signal reflected off the room surfaces, to have a coherent
balance. This means a consistent high sound quality
across a much wider listening area. At the same time, it
offers greater freedom and flexibility in positioning the
loudspeakers.

WOOFER
When developing the SPEKTOR series, a large part
was devoted to bringing as many DALI technologies to
the drivers as possible. This is especially true with the
woofer, where elements like the wood fibre cones, the
low-loss suspension, chassis layout and magnet motor
design where crucial elements in the overall design.
The wood fibre cone structure is not only a DALI
trademark, but a well proven technology. By crafting the
cone membrane from a mix of fine grained paper and
wood fibre pulp, the cones become very ridged, very
light weight and the unevenness of the membrane helps
minimize unwanted surface resonances.
Combining the well-behaving wood fibre cone with the
low-loss surround and spider suspension results in the
reproduction of even the smallest micro-detail in the
signal – unfiltered and with high accuracy.
The structure of the chassis holding the low-loss
suspension, wood fibre cone, 2-layer voice coil, magnet
motor system, and forming the entire contact surface
area with the front baffle, was designed for optimal
strength and airflow. Keeping the woofer structure strong
eliminates internal vibrations and the optimised airflow
around the cone area keeps movements unhindered,
resulting in the ability to transform as much of the
energy from the amplifier into movement.
Wood fibre cone, low-loss surround and a strong
magnet motor system results in the reproduction
of even the smallest details.
Having a strong magnet motor system combined with
a nimble 2 layer 25 mm voice coil, keeps the coil
movements precise, well timed and powerful.
Every woofer used in the SPEKTOR series is developed
specifically for the speaker they are used in. Even small
details like the angle of the cone and the size of the
dust cap is optimized for the best possible integration,
dispersion and performance.
The bass ports are placed right
behind the woofers for maximum
airflow and minimum damping effect.

TWEETER
The tweeter must be able to render high frequencies
with high accuracy. This means very short excursions,
but at high speed, - or rather – with high acceleration.
In other words, a low moving mass and a strong motor
is needed.
The SPEKTOR tweeter is based on an ultra-light weight
weaved fabric. Compared to most soft dome tweeters
in the market, the DALI dome material is less than half
the weight; 0.056 mg per mm
2
The beauty of the soft dome tweeter is its impressive
ability to play even the lowest parts of the high
frequency range without any break-ups. This is crucial
when handling the all important hand-over from the
woofer to the tweeter. Not having to push either the
woofer or tweeter beyond what they do best results in
a seamless transition and preservation of every detail
in the mid-range frequencies.
The geometry of the tweeter front plate near the dome
has been optimised to create the perfect working
conditions for the soft dome. The aim was to combine an
extended frequency response with wide dispersion and
low coloration.

WIDE DISPERSION
DALI makes it easy to integrate your loudspeakers
into any room. Both the driver materials and geometry
applied in the SPEKTOR series have been selected to
achieve a wide dispersion pattern.
You will experience a well-integrated sound, even
when listening significantly off-axis. And, as you are
often not seated directly in front of the loudspeaker
when listening to music, this is important.
An added benefit is hugely reduced harmonic
distortion and diffractions causing frequency
distortion, as these will always be stronger in an onaxis response.
That is also the reason why all DALI speakers are not
designed for toeing-in.
DALI speakers is build for wide dispersion, filling the
room with the best quality audio and enlarging the
listening sweet spot.
