Masterpiece

SA explorer master stands on the shoulders of SA explorer and sets a new standard for audio experiences.
Using new technology, extensive listening tests and the construction of a unique listening and measurement laboratory, the SA explorer master is a reality. A masterpiece that will delight and inspire its users every time they hear it.
It has taken almost 10 years to create the SA explorer master. The original SA explorer was completed after a full 5 years of development work and is a remarkable speaker with an enchanting musicality and energy.Technologically, the SA explorer offers many groundbreaking ideas that make it durable for many years. There was no speaker like SA explorer before now.

Master is the real overman

The SA explorer master contains the results of the development work that has been made possible since the presentation of the original SA explorer. Completely new methods of developing acoustics and electronics have been adopted, and the SA explorer master is the first loudspeaker of its kind.

Developed in special test room

To create the SA explorer master, a special test room with controlled acoustics had to be built. This was necessary so that the measuring equipment could capture the sound of the loudspeaker with the greatest possible accuracy. Next, measurement methods were used that clarify in a new way how our human ears perceive sound. With this new knowledge, we could create our master. A speaker built in many ways like its model, yet offering more of everything.

Only in SA explorer master

Inside the speaker, the materials are optimised so that air moves more freely and creates less compression. This part of the speaker design has been optimised in SA speakers for many years, but in the SA explorer master we have gone even further. The sub-filter, the speaker's electrical circuitry, has been conceived in a new way. The crossover's job is to distribute the sound signal to the speaker's various speaker elements, and the new crossover in the SA explorer master processes the sound signal in an even more gentle way so that important information is not lost. One of the reasons for this is the improved acoustics inside the speaker. The new crossover and improved acoustics have led to one of the world's best cables, Nordost Monofilament, finding its way into the SA explorer master's tweeter. The four bass/midrange speakers are connected with Nordost Wyrewizard cables.

Design

On the back of the speaker you will find a discreet label that says "master version", but there are other ways to recognise an SA explorer master. It has a black base, black front baffle and the cover plate under the fabric frame lies flush with the fabric surface. The SA explorer master is also produced in a beautiful high-gloss black finish.

Experiences you can't escape

SA explorer master is the loudspeaker for you who want to treat yourself to top-class present sound experiences. The time you spend entertaining is precious and should grab you, whether you're in the mood for contemplation or pleasure.

World-class know-how

When you want to set a new standard, it's no good following the traditional way of thinking, or imitating what others in the industry are doing. The development team behind the SA explorer master couldn't work like that. They know that real progress - what really makes a difference - can only be achieved by thinking further and breaking the boundaries we know today.

An acoustic masterpiece

Acoustics and technology merge in SA explorer master, giving you an experience that may be the closest a speaker can bring you to the true live sound experience. The simple and clean lines of the design hide a powerful and advanced construction that has been developed from the ground up. From the very beginning, SA explorer master was meant to impress with its performance, without making a showy appearance. SA explorer master is the ambitious solution to the task of conveying top-class sound quality in balanced integration with your other furniture.

Acoustics - the invisible quality of the loudspeaker

Acoustics is one of the least visible sciences. But the presence of excellent acoustics liberates sound and gives you an extraordinary experience. Acoustic perfection is only one of our goals, and when we develop speakers, we start far from laboratories and measurement rooms. Our speakers are created to work in the homes of the people who choose to live with them. A number of the world's leading acoustic engineers have contributed in the nearly 10 years of work to develop the SA explorer master. It can be hard to see. But you can't help but hear it.

A sound spread made for a home - not a laboratory

In an ordinary home, both the floor and the ceiling are smooth surfaces, almost without refractions or variations. The walls, on the other hand, are lined with various pieces of furniture that shape the acoustics of the home. The smooth floor and ceiling surfaces usually create a lot of reflections that make the sound unnatural, while furniture in the room and along the walls create much fewer reflections. Therefore, the sound from SA explorer master radiates less towards the floor and ceiling than you are used to from other speakers. In addition, the narrow design helps to prevent reflections from the front of the speaker, while the relatively deep cabinet prevents sound reflections from inside the speaker from propagating out through the diaphragms of the speaker elements. You can hear all this clearly, as the reduced reflections and excellent acoustics of the speaker help to give you a lifelike experience of being close to the performers.

A sound that's right in your ear

SA explorer master can be placed exactly where you want it - although it pays to experiment with placement when you want the optimum sound. And when you sit in front of the speaker, the sound is delivered right at ear level, giving you the experience of sitting right in front of the performers.

Specialists work together to deliver perfect sound

In the SA explorer master, the different components work together to reproduce the sound. Each component is specially designed to do its part: the actual bass tones are reproduced by four specially designed woofers, with the diaphragms under the influence of as many as eight built-in voice coils, ensuring lightning-fast and controlled low bass. The higher bass tones are reproduced by the same diaphragms, but driven only by one of each speaker's two voice coils. The midrange is reproduced by the two upper bass elements. The highest notes in the audible range are reproduced by the custom-built tweeter. The lowest notes are emitted through two tubes at the rear of the cabinet - an ingenious and simple solution that takes advantage of the fact that the low notes propagate like rings in water, and are therefore heard with equal clarity all around the speaker - even in front.

Building the SA explorer master

Better sound quality starts with a better speaker cabinet. A stronger and more vibration-free cabinet, sized acoustically correctly, gives the speaker elements better working conditions and thus more natural sound.

SA are specialists in small, high-performance woofers

It's no surprise that SA is introducing technologies like XL technology, which delivers big sound from small speakers. After all, we've never done anything else. Back in 1984, when System Audio A/S was founded, the key difference between the very first SA speaker and all other speakers was that the SA speaker used smaller woofers. We demand speed and precision from our loudspeakers because it gives more nuance to the sound and makes it easy to follow the music. When we require a speaker to be able to play very loud, we don't use large woofers, but several small ones.

The T2506XS tweeter is an acoustic masterpiece

Acoustics, precision engineering and musicality come together in the T2506XS tweeter, delivering a stunningly nuanced reproduction of sound detail.
  • XS technology means that a wave guide around the tweeter con- trols the sound's radiation so that it is not reflected from the cabinet's front panel
  • XS technology also ensures that the tweeter radiates sound over a larger area than any traditional tweeter. You can move around, or sit in different places, and still experience consistent sound quality throughout the room. XS technology increases the area in front of the speakers where you can experience optimal sound quality
  • A 12 mm cast aluminium faceplate provides a vibration-free foundation for the tweeter's delivery of information that can require precise diaphragm movements as small as 0.0005 mm!!
  • Unique textile membrane weighing only 80 mg
  • Built-in separate chamber behind the diaphragm
  • Resonances caused by the sound from the back of the membrane hitting the bottom plate of the magnet are eliminated by means of three small blocks of different materials that can be seen through the almost transparent membrane.
  • The T2506XS tweeter is magnetically shielded
  • XS technology only available in SA speakers
