Description
The Børresen X Series is not only the new entry level in the Børresen universe, but also a true revolution in quality and performance in its price range. These speakers are based on all the knowledge gained from the M, 0 and Z series.
Product information
The X series magnetic motor system uses double copper caps on the pole rings to achieve high flux and low inductance. The use of copper caps was borrowed from Børresen's Z series. Copper reacts to changes in flux - the better the resistance of these copper rings, the flatter the inductance curve and the lower the electromagnetic resonance. In addition, lower inductance means fewer spikes in the impedance curve. Both result in less load on the amplifier. To ensure high efficiency, the X-Series has two pole rings. This leads to a loss of some flux, which reduces efficiency, but it is compensated by a larger magnet.
The tweeter chosen for the Børresen X-series is the same design as in all other Børresen speaker series. However, the weight of the magnet and iron has been reduced. This was made possible by the extremely high efficiency of the original tweeter design. As a result, the efficiency has only slightly decreased from an exceptional 94 dB to 90 dB, but this is still an amazing figure for a tweeter.
The Børresen X-Series features a parallel crossover built with the same high-quality components as the Z-Series. This makes the crossover very mechanically stable and minimizes its self-resonance.
The surface of the case is covered with black or white piano lacquer and reinforced with carbon fiber inserts. The case is made of wood-composite material, which has the ability to eliminate sound distortion. The material of the case also reduces mechanical effects, especially hysteresis. The sound result is clearly audible. X-Series is equipped with phase inverter ports for low frequencies. The tweeter is ventilated to compensate for air pressure build-up. The bass section consists of tuned ports calibrated to musically relevant frequencies.
