Any distortion or coloration of the original signal by drivers or enclosures is by definition degradation of the sound.
DALI loudspeakers are designed in accordance with our fundamental acoustic and electro-acoustic principles, which together bring you even closer to the full impact of a live music experience.
1. 3D Sound :
Low-loss technology is a key characteristic of DALI loudspeakers. By choosing our "building materials" with great care, we make sure that no signal is lost or changed on its way through the loudspeaker.
You experience a richly detailed, true-to-life sound, spread evenly throughout the room.
When listening to DALI loudspeakers, you will not be able to point out the exact location of the loudspeaker. You hear exactly the sound the artist intended. For example, if the artist wants you to hear sound coming from certain angles, DALI loudspeakers master this perfectly. DALI low-loss technology, in combination with Time Coherence, creates true 3D Audio in stereo and in surround.
2. Aplifier Optimized :
Impedance is the measure of the resistance of the loudspeaker at different frequencies and should ideally be the same at all frequencies.
Smooth, even impedance means better working conditions for the amplifier, resulting in higher resolution. The job of the amplifier and loudspeaker is to reproduce the signal exactly as it is, adding nothing and removing nothing.
If the impedance of a loudspeaker changes at different frequencies, the amplifier encounters constantly varying resistance, making it much harder to follow the signal/music.
Linear impedance - a stable load for the amplifier - is a high priority at DALI and is achieved by fine-tuning every aspect of the speaker design.
We have a very high standard that is ensured by a Quality Management System.
Among many other things, this system ensures that no loudspeaker leaves our factory without having been rigorously tested, both acoustically and visually.
After a thorough inspection, including a complete electro-acoustic test measurement procedure, on most speakers the person who assembled the loudspeaker signs a label on the back of the speaker to prove that the speaker has been tested and approved.
4. Time Coherence :
When tuning the performance of every DALI loudspeaker, our engineers put great effort into the "teamwork" of the drivers, crossover and the cabinet.
This allows you to experience focused, coherent sound without any unwanted interaction between the drivers.
The sound from the different drivers is synchronised to arrive at the ear at the same time. Studies show that loudspeakers with excellent time coherence deliver enhanced sonic realism.
Time coherence is a must in any DALI speaker.
5. Wide Dispersion :
We carefully select driver materials and geometry as well as design the crossover especially to achieve wide dispersion.
DALI loudspeakers fill a wider area of the room with smooth, integrated sound. We design our loudspeakers for optimal frequency response (consistent sound pressure regardless of frequency), even for listeners seated off-centre.
This is important, as one rarely sits directly in front of the loudspeaker when listening to music and as the sound from the speaker arriving at the ear is always mixed with reflections from the surfaces in the room.
6. Low Resonance Cabinet :
When sound is created by moving air, it is reflected off room surfaces and inside the loudspeaker.
Reflections press on the rear of the drivers, standing waves bounce back and forth between cabinet surfaces; structural resonances cause panels to vibrate.
For the most correct and true-to-life sound, internal reflections and vibrations must be reduced as much as possible. DALI achieves this through optimal cabinet design based on the finest - sometimes very complex materials and geometry.
In many cases, we also use strong internal bracing and separate chambers to effectively reduce coloration.
