With its new BM Prime series Backes&Müller has once again set new standards in the conception and construction of modern HiFi loudspeakers. FIRTEC technology, which is known due to the multiple award-winning Line series loudspeakers, is being used for the first time in the current Prime line. The “time-aligned” reproduction technology developed by Backes&Müller is therefore now featured in the Prime models offering a new standard of music enjoyment. In connection with the B&M proprietary DMC membrane control, the Prime models build a holographic-plastic stage in front of the listener, which was hitherto only known in Line series models. Backes&Müller was a pioneer on the market with this type of sensor regulation 40 years ago and elevated loudspeaker reproduction to a new level of quality. In the last two years we were able to increase the precision of DMC membrane controllers by a factor of 4 again via new computer supported developments (patent pending) and connect it to our FIRTEC equalisation. We have thus created a world-wide unique phase linear music reproduction from the deepest bass to the highest treble without design-related limits in the desired listening volume. This brings the listener truth in the reproduction with even more information and pushes the listening experience close to the veracity of live events.

Our cabinet construction with the finest materials is a solid fundament and home for our chassis and drivers. The installed chassis are partly built in-house – for example the mid-tone driver calottes of the BM Prime12 - or manufactured to B&M specifications by specialists in Germany. Incidentally just like all other components as well, even the mounting of the complex SMD-equipped circuit boards are high quality and made-to-measure German craftsmanship.

The design is extraordinary without any extravagance, unpretentious and suitable for every living ambience with our broad palette of different finishes and surfaces. Whether in fine veneers or timelessly elegant black or white, a Backes&Müller Prime series loudspeaker is a statement of good taste in every home. In spite of its pioneering role in modern signal processing no technology is evident, not a screw nor a clamp in sight; nothing that could disturb the design of our timelessly beautiful sound furniture. The materials used for the inserted chassis are chosen from an acoustic-optical point of view, nothing may only look or sound good and we seek the perfectly balanced combination. Thus the treble driver of the BM Prime series models must not only be extremely performant with plenty of reserve, it sits in an aluminium cylinder that has been worked out of a solid block of aluminium by high-gloss turning technology. This cylinder leads to three advantages in one workpiece: The surface is formed to a waveguide, which makes the cabinet edges of the loudspeaker invisible for the high frequency range. The solid material gives the driver an exact fit without any play or tolerances whatsoever. The surface of the visible part of this aluminium block is extremely distinguished through the polishing and sealing and gives the loudspeaker an unmistakeable look. The mid-tone calotte chassis is also a B&M in-house development; the calotte is deep-drawn in our factory and the surface is sealed with a complex varnishing technique. In connection with the driver we have succeeded in creating a middle-tone chassis of our own quality class whose transmission band transforms music into sound quasi feature-free without any resonances or decaying oscillations. In this way, many details in the construction of the new BM Prime line are dictated by best performance in the best look.





Details Prime 14

Powerful yet slim, that’s the way the new BM Prime 14 looks. Even though the cabinet volume has grown considerably in comparison to the previous model and the sound performance correspondingly, the loudspeaker nevertheless seems narrower. This optic is achieved by the side panels framing the baffle board. The listener therefore has a simultaneous view of the noble veneer’s structure along the lateral edges, an appealing contrast between the velvety Nextel finish and the wooden surface. The contours of the entire new Prime series in the direction of the front panel are somewhat edgier and more contemporary. The polished structured lacquer finish highlights this even more and promotes a rich appearance of the noble wood surface.

With the lower cut-off frequency of less than 25 Hz it goes decidedly down deep, precise and dry DMC2.0 regulated, so that the use of a subwoofer is also superfluous for the lowest octave. Our signal processor using FIRTEC on four regulated 17 cm chassis and air motion transformer (AMT) also works in our BM Prime 14. Tonally extremely balanced, exemplary music reproduction without any time distortions whatsoever brings the perfect stage to your living-room. Voices, piano, percussion and string instruments or an entire orchestra effortlessly unfold their sounds in the listening room. In combination with the chassis and the AMT the cylinder wave directs its acoustic energy to the listener’s position and adequately dampens reflexions in the listening room. Therefore one sits closer to the music event with goose bumps guaranteed!
