Master Line Source III

This innovative dipole speaker enables an extraordinary music experience anywhere in your living.

The Master Line Source III is designed as a line source speaker with dipole radiator characteristics. Four ribbon tweeters guarantee a supremely natural, detailed and spatial sound. This is enhanced by the two 180 mm woofers and two same-sized passive radiators with a powerful bass foundation.

The only 23 centimeter wide baffle has been provided with a smaller and specially crafted version of the ribbon for the midrange/high frequency range. These four ribbons were installed above each other in a line. They operate on the dipole principle and radiate the sound to the front and rear simultaneously in the form of a vertical cylindrical sound wave. A slatted acoustic lens here ensures the production of a completely diffuse sound field behind the Master Line Source III.

- The MLS 3 with its height of 165 cm, is the smallest loudspeaker of the Master Line Source Series and is ideally suited for larger living rooms.

- Two completely new 180 mm UHQD bass units and two UHQD passive membranes are used to provide a powerful bass.

- The rear acoustic lenses diffuse the sound extensively allowing you to place this dipole speaker in your living room like a conventional speaker.

- Like the MLS two, the MLS 3 was also developed in close collaboration with Swiss designer Stephan Hürlemann and is available in four different finishes.

The supreme discipline in speaker construction is natural voice reproduction. The particular challenge lies in the detailed reproduction of fast impulses. Since our beginnings, we have relied on tape systems that master this task. Simply put, a ribbon is a wafer-thin foil membrane that produces sound through its vibration. The special feature is that the membrane, in combination with strong magnets, becomes its own drive. This acts evenly over the entire surface and makes it possible to install a wafer-thin membrane. The lighter the membrane, the higher the level of detail. The ribbons of the Master loudspeakers are designed as line sound sources. This means that the sound waves are radiated along a straight line and spread out in a cylinder-like manner in the room without reflecting off the ceiling or floor. With the Master Line Source 3, we implemented this principle by cascading four ribbons at the same time. Four volumes mean four times more musical passion. The result: a level of meticulousness that convinces even the most sensitive ears.

The MLS 3 is a front and rear radiating dipole, which means that the music is reproduced evenly throughout the room. The rear acoustic lenses ensure that a diffuse sound field is created behind the speaker. This allows the speaker to be placed close to the wall. This dipole system puts you right in the middle of the musical action.
