DALI SPEKTOR 1 Walnut

WIDE DISPERSION

DALI makes it easy to integrate your loudspeakers into any room. Both the driver materials and geometry applied in the SPEKTOR 1 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.

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.

An added benefit is hugely reduced harmonic distortion and diffractions causing frequency distortion, as these will always be stronger in an on-axis response. This is also the reason why all DALI speakers are not designed for toeing-in.

TWEETER

The SPEKTOR 1 tweeter is 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, it features a low moving mass and a strong motor.

The tweeter in SPEKTOR 1 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 mm2.

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.

WOOFER

The wood fibre cones are a DALI trademark, as well as a proven DALI technology. The SPEKTOR 1 cone membrane is crafted from a mix of fine grained paper and wood fibre pulp. This makes the cones very ridged, very light weight and the unevenness in the structure of the membrane helps minimize unwanted surface resonances.

Combining the well-behaving wood fibre cone with the low-loss rubber 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 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.

The woofer used in the SPEKTOR 1 is developed specifically for this speaker. 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.

LOW LOSS

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.

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.

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 out of quality components which ensures that the signal loss is close to zero.

Another fundamental is the lowering of mechanical distortion. This to make sure that the connected amplifier will not be exposed to 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.
