A revolution in quality, performance and price
Børresen has developed a new entry-level loudspeaker at an affordable price, making the Børresen loudspeaker universe accessible to more people. The Børresen X3 loudspeaker has been designed on the solid foundation of Børresen Acoustics’ development traditions, design philosophy and technological know-how.
Technologies and Components
The Børresen X series loudspeakers are not only a new entry level to the Børresen universe, but also represent a true revolution in quality and performance in their price range. These loudspeakers are created based on all the knowledge gathered in the process of creating the M, 0 and Z series. You’ll find components from these unique series in these Børresen X series loudspeakers, for example the new Spread-carbon membrane. tow, the highly praised Børresen ribbon tweeter, and the use of copper caps on the magnetic motor system.
X-Series Cone – Bass/Mid
This membrane is designed to achieve maximum rigidity with minimum noise. The technological requirements for the unmatched performance of this high-end membrane made it necessary to design, develop and assemble all components in-house.
The X3 membrane consisting of three layers laminated into a single unit: two layers of extended carbon fiber, with a layer of aramid honeycomb spacers in between.
The combination of these materials gives this membrane its unique properties. The extended carbon fiber was designed to provide a skin with optimal rigidity. This unique characteristic of the membrane reduces sound-disturbing vibrations and resonances to unprecedented levels. Aramid honeycomb also has the best stiffness-to-weight ratio in the vertical direction. A membrane with a flat response in terms of resonances paved the way to build a highly transparent loudspeaker with a reduced size of the magnetic motor system to optimize costs.
X-Series Magnet System – Bass/Mid
In the X3 magnetic motor system, we use double copper caps on the pole rings to achieve high flux and low inductance. The use of copper caps has been adopted from Børresen’s Z series. Copper produces a response to flux changes: the better the counter effect of these copper rings, the flatter the inductance curve and the lower the electromagnetic resonance. Additionally, lower inductance also means fewer spikes in the impedance curve. Both result in a lower load on the amplifier. To ensure high efficiency, the X3 has two pole rings. This causes some flux to be lost, which reduces efficiency, but this is compensated for by a larger magnet.
Borresen X-series tweeter
The tweeter chosen for the Børresen X3 has the same design used in all other Børresen loudspeaker series. However, there is a reduction in the magnet and the mass of iron. This is made possible by the extremely high efficiency of the original tweeter design. As a result, the efficiency has dropped only slightly from an exceptional 94 dB to 88 dB, but it’s still amazing efficiency for a tweeter.
The tweeter works from about 2.5 kHz upwards. The moving mass is extremely low at 0.01 grams. The fully concealed tweeter can work at impressive speed. The high robustness of this tweeter allows it to handle very high transients without causing deafening dips.
X series filter
The Børresen X3 is equipped with a parallel crossover built with the same high-quality components as the Z Series. This makes it a very mechanically stable crossover that minimizes its self-resonance.
X series chassis
The furniture surface is finished in glossy black or white lacquer and reinforced with carbon fiber inserts. The cabinet is made of a heavily reinforced wood composite material that has the property of eliminating sound distortion. The material used for the cabinet also reduces mechanical influences, especially hysteresis. The sound result is clearly audible. The Børresen X3 cabinet has six bass reflex ports. The tweeter is vented to compensate for the air pressure that builds up. The bass section consists of tuned ports calibrated for musically relevant frequencies.
