Børresen X1 (on sale)

Børresen X1 - High-end compact speaker with a big soundstage

Børresen X1 is a compact and exceptionally great-sounding speaker that gives you incredible value for money. With X1, you gain access to Børresen’s know-how, which they have developed through the creation of their exclusive M-, 0-, and Z-series. This has resulted in a woofer/midrange driver with the innovative spread-tow carbon diaphragm, one of the world’s lightest ribbon tweeters, and the use of copper caps in the magnetic motor system. Combined with the droplet-shaped cabinet, which effectively eliminates internal standing sound waves, you get a level of sound quality that is groundbreaking for its class. The sound is harmonious and has a weight far greater than its physical size would initially suggest. Vocals are delivered with the utmost openness and richness of detail, making it an incredibly musical communicator.

Technologies and components

Børresen X1 may indeed be an entry-level model in the Børresen family, but that should not fool you. Børresen’s entry level is still high-end hi-fi, and X1 represents a remarkable step forward in quality and performance in its price class. These speakers benefit from all the knowledge gained through the development of the M, 0, and Z-series. Components from these exclusive series have been incorporated into the Børresen X1 speakers, including the groundbreaking spread-tow carbon diaphragm, the highly acclaimed Børresen ribbon tweeter, and the use of copper caps in the magnetic motor system.

X1 series diaphragm – woofer/midrange

The groundbreaking diaphragm in the X1 series is designed with the goal of achieving maximum stiffness and minimal noise. To achieve this unmatched performance, all components were designed, developed, and assembled in-house. The X1 diaphragm consists of three layers laminated into a single unit: two layers of spread carbon fiber with a layer of aramid honeycomb spacers in between. This unique combination of materials gives the diaphragm its exceptional properties. Spread carbon fiber is shaped to provide optimal stiffness, reducing disruptive sound vibrations and resonances to unprecedented levels. Aramid honeycomb has the best stiffness-to-weight ratio in the vertical direction. The diaphragm’s flat response with regard to resonances makes it possible to create an extremely transparent speaker with a smaller magnetic motor system to optimize costs.

Unique magnetic motor system

In the X1 series magnetic motor system, double copper caps are used on the pole ring to achieve high flux and low inductance. This technology has been borrowed from the Børresen Z-series. Copper helps reduce electromagnetic resonance by counteracting changes in flux, resulting in a flatter inductance curve and fewer peaks in the impedance curve. This reduced inductance places less strain on the amplifier. To ensure high efficiency, X1 is equipped with two pole rings, and any loss of flux is compensated for by a larger magnet.

Ultra-light tweeter without distortion

The tweeter in X1 uses the same basic design as in all other Børresen speaker series. However, a reduction in magnet and iron mass has been achieved thanks to the extremely efficient design. This results in only a slight reduction in efficiency, going from the remarkable 94 dB to 90 dB, which is still impressive efficiency for a tweeter. The tweeter operates from approx. 2.5 kHz and up. With an extremely low moving mass of just 0.01 grams, the tweeter can respond incredibly quickly. Its high robustness makes it possible to handle very sharp transients without causing damped tones.

Premium crossover parts from the Z-series

Børresen X1 is equipped with a parallel crossover that uses the same premium components as the Z-series. This results in a very mechanically stable crossover that minimizes self-resonance.

X1 series cabinet

The cabinet surface is elegantly finished in black piano lacquer and reinforced with carbon fiber inserts. The cabinet is made from a heavily reinforced wood composite that eliminates sound distortion and reduces mechanical influences, including hysteresis. This construction provides superior sound reproduction. The X1 series is equipped with bass reflex ports, and the tweeter is vented to compensate for building air pressure. The bass section contains tuned ports calibrated to musically relevant frequencies.

Børresen X1 combines these technological innovations and components to deliver a remarkable listening experience. The exceptional diaphragm, advanced magnetic motor, and high-performance tweeter ensure that music is reproduced with incredible clarity and precision. This speaker series offers exceptional quality and performance in its price class and is the ideal choice for audio enthusiasts seeking an affordable entry into the Børresen universe. Børresen X1 is not just speakers - it is your gateway to an outstanding musical experience.
