The Børresen X series loudspeakers are not only a new intro-level into the Børresen universe, but also represents a real revolution in quality and performance in its price range. These speakers are created based on all the knowledge collected in the process of the creation of the M, 0 and Z-series. You´ll find components from these exclusive series in this Børresen X series loudspeakers – for instance the brand new Spread-tow carbon membrane, the highly praised Børresen ribbon tweeter and the use of copper caps in the magnetic motor system.
This membrane is designed to achieve maximum stiffness with minimum noise. The technological requirements for this unrivaled high-end membrane performance made it necessary to design, develop and assemble all components in-house.
The X-series membrane that consists of three skins laminated into a single unit: two layers of spread carbon fiber, with a layer of aramid honeycomb spacers in between.
The combination of these materials gives this membrane its unique properties. The spread-tow carbon fiber was designed to provide a skin with optimal stiffness. This unique feature of the membrane reduces sound-disturbing vibrations and resonances to unprecedented levels. The aramid honeycomb also has the best stiffness-to-weight ratio in the vertical direction. A flat response membrane in terms of resonances paved the way to build a very transparent loudspeaker with a reduced size of the magnetic motor system to optimize costs.
The tweeter chosen for the Børresen X-series has the same design used in all other Børresen loudspeaker series. However, there is a reduction in magnet and iron mass. This is possible due to the extremely high efficiency of the original tweeter design. As a result, the efficiency has dropped only slightly from the exceptional 94 dB to 90 dB, but this is still an amazing efficiency for a tweeter.
The tweeter operates from about 2.5 kHz upwards. The moving mass is extremely low at 0.01 grams. The fully concealed tweeter can operate at an impressive speed. The high robustness of this tweeter allows it to handle very high transients without causing any deafening dips.
