Master Line Source 2

The Master Line Source 2 is a smaller version of the Master Line Source, which can also be integrated in normal living rooms.

Impressive appearance

Although the MLS 2, with a total weight of 93 kg, is considerably lighter than the MLS with its 176 cm height, it is slightly taller and is thus also the largest of PIEGA's loudspeakers.

Group 18

Brilliant midrange/tweeter sound

Four Line Source Driver ribbons ensure unforgettable sound reproduction for all midrange and high frequencies.

Group 18

Solid bass power

Two 220 mm UHQD subwoofers and two equally sized UHQD passive membranes radiating at the back provide a powerful bass sound.

Group 18

Acoustic lenses

The rear acoustic lenses distribute the sound so expansively that it is possible to place a dipole speaker in the room like a conventional loudspeaker.

Group 18

Swiss design

The MLS two was developed in close collaboration with Swiss designer Stephan Hürlemann and is available in four different cabinet designs.

Group 18

Acoustic lens with lamellae

The combined mid-range and tweeter ribbons, termed the line source drivers, emit sound, firstly, directly to the front. In addition, their sound, which is emitted backward consistent with the dipole characteristic is transformed into a wholly diffuse sound field by way of an elaborately engineered acoustic lens. Using diffraction and reflection, lamellae composed of painted MDF distribute the sound so expansively that it is only possible to place a dipole speaker within a space as a conventional loudspeaker if the MLS 2 is deployed.

Non-oscillating cabinet

In order to uncompromisingly leverage the drivers’ high quality and lack of distortion, utmost care has been taken to ensure a lack of vibration in the cabinet. The Line Source Drivers are mounted within a 10 mm thick aluminium baffle, the entire surface of which is glued to the actual cabinet. This consists of a composite of MDF boards and the viscoelastic heavy- duty film – an extremely solid and rigid structure. These provide a perfect operating environment for the two PIEGA woofers, with a Diameter of 220 mm, also newly developed, as well as for the two rear passiv oscillating radiators.
