Nefes II Loudspeaker

Nefes II Loudspeaker

Following decades of experience in design and production of uniquely direct coupled loudspeaker drivers, the Reference 3A team has done it again. Our relentless pursuit of excellence and use of advanced materials has resulted in creating our new, very precise crossover-less drivers that are the heart of our new Nefes loudspeaker.

Receiving uninterrupted musical signal, propagating it coherently and precisely, the Nefes loudspeaker breathes life into your favourite music.

Two of these superb 8” full range drivers and a pure Beryllium dome tweeter are assembled in a vertical array into a very rigid and inert cabinet making the foundation of our new Nefes loudspeaker model. The Beryllium tweeter is mounted behind an exponential acoustic wave guide for better time alignment and more uniform dispersion patterns.

With no crossover on the main drivers (just a very high quality capacitor) the high pass filter on the Beryllium dome tweeter sounds dynamic, fast, articulate and very coherent. It has an unusually wide frequency response with the bass extending down to 26 Hz and the high frequencies reaching past 40 k Hz. It is also very efficient at 92 dB and presents a very easy impedance load of 8 Ohms to amplifiers.

To further refine the performance of our new model Nefes – patented Surreal Acoustic Lenses for diffusing inherent driver cone turbulence noise and patented Magnetic Wave guides to purify the incoming audio signal are also used. Cryogenically treated, Teflon insulated, pure OCC copper conductors in appropriate thicknesses for each driver and copper input connectors are also used to ensure perfect signal transmission.

Housed in extremely rigid and inert loudspeakers cabinets, the Nefes is finished in a durable anthracite coloured, matte textured Nextel coating. This special coating effectively absorbs sound and light for acoustically and visually silent cabinets.
