BORRESEN X3 Floor Standing Loudspeakers

Product Information

Loudspeaker
The loudspeaker is a high-quality audio device designed for optimal sound reproduction. It features a tweeter with strong magnets and a low moving mass, allowing for impressive speed and handling of high transients without distortion. The X3 loudspeaker has two pole rings to ensure high efficiency, although this may slightly reduce its overall efficiency compensated by a larger magnet. The loudspeaker should be used with high-quality amplifiers that operate within the specified power ratings to avoid damage.

Safety Instructions

• Avoid bringing external metal objects close to the loudspeaker as it can cause damage due to the strong magnets in the tweeter.
• Use only high-quality amplifiers and ensure they are not too weak, defective, or overloaded to prevent damage to the loudspeakers from distorted output signals.
• Let the speaker reach room temperature before plugging it in to prevent condensation and potential damage to the electronic circuitry.
• Wear protective gloves when handling the loudspeaker to protect its surface.
• Avoid using the product in damp settings, inserting foreign bodies into the bass reflex ports, touching the speaker elements, or using a vacuum cleaner to remove dust.
• Clean the surface of the loudspeakers with a firmly wrung, damp cloth without using any detergent that may discolor the finish.
• Avoid exposing the cabinets to direct sunlight.

CONGRATULATIONS
The Børresen audio engineering team are grateful and congratulates you for your choice of the Børresen loudspeakers. We are convinced that you will enjoy the exquisite music experience just as intimate and close as it was originally performed by the artist themselves. Børresen Acoustics’ philosophy is to bring people closer to the music by creating access to great, authentic and emotional music experiences. Børresen believes that everyone deserves these kinds of wonderful moments. The Børresen X3 has been designed on the solid foundation of Børresen Acoustics’ development traditions, design philosophy and technological know-how.

ABOUT THE PRODUCT

X-series membrane

• To ensure the typical Børresen characteristics in the X3 loudspeaker, Michael Børresen and his team of designers and engineers were able to draw on the development process and technology of the newly created Børresen M1 membrane.
• 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.
• Michael Børresen and his team designed many different variations and models until they finally achieved their uncompromising goal of ultimate membrane performance for unprecedented sound quality. The result is the X3 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 magnetic motor system

• In the X3 magnet motor system, Børresen uses double copper caps on the pole rings to achieve high flux and low inductance. The use of copper caps has been adopted from the Børresen 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.
• In addition, 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 the loss of some flux, which reduces efficiency, but this is compensated for by a larger magnet.

The 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 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 88 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.

Crossover

• The Børresen X3 is equipped with a parallel crossover built with the same high-quality components from the Z Series. This makes for a very mechanically stable crossover that minimizes its self-resonance.

The cabinet

• The surface of the cabinet is finished in black or white piano lacquer and reinforced with optical carbon fiber inserts. The cabinet is made of a heavily braced wood composite material that has the property of eliminating sound distortion. The material used for the cabinet also reduces mechanical influences, especially hysteresis. The sonic 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.

UNPACKING

9. Please observe the guidelines for positioning and connecting your loudspeakers on page 7 and 8.

CONNECTING THE SPEAKERS

• With every connection system, ensure that the contact is tight and has a proper contact area.
• Connectors with gold plating will typically offer the best results and remain corrosion-free.
• Please ensure that the positive and negative cables do not make contact with each other.
• Check the connectors from time to time to make sure that nothing has loosened.

1. Connect a two-pole (+/-) loudspeaker cable to the binding posts, located at rear of the loudspeaker.
   The high-quality binding posts can accommodate only 4-mm-plugs (“banana plugs”).
   The pins can be put directly into the binding post without any tightening necessary.

2. Connect the other cable ends to the loudspeaker outputs of your switched-off amplifier.

POSITIONING

The sound from loudspeakers depends very much on the room and on the way they are set up. Please consult your dealer for advice on how to set up your Børresen loudspeakers in your home.
These guidelines are general and will give you a good starting point for further experimenting in finding out what is just the right setup for your room.

The distance from the side walls to the loudspeakers

• The Børresen loudspeakers are not that sensitive in regard to getting to close to sidewalls. A distance of about 15 cm will be enough. Too short a distance to the side walls is likely to increase the amount of bass.

The distance between the rear of the loudspeakers and the wall behind them

• Start with a distance of 50 cm. This distance should be exactly the same for both loudspeakers. Try the loudspeakers out with music you know and find out what distance gives the best sound.
• Greater distance = weaker bass, more precise bass, better precision, and bigger sound stage. Shorter distance = more and softer bass, and a smaller sound stage.

The distance between the loudspeakers and the listener

• The ideal distance between the loudspeakers is not less than 3 meters. Put the loudspeakers in an angle making the center point at the listener’s shoulders. The lines should cross about one meter behind the listeners head, meaning that the listener should just be able to see the two inner sides of the speakers.

BURN IN

• All new high quality loudspeakers need a certain period of burn in time. As Børresen loudspeakers uses long-stroke bass driver with natural rubber surrounds, the loudspeakers needs at least 50 – 100 hours of actual music playing at decent sound level.
• You will notice a gradual improvement in sound quality.
• No particular precautions need to be taken during those hours.

RECOMMENDED PRODUCTS

Ansuz loudspeaker cables

• Børresen recommends using high-quality loudspeaker cables together with these high-end speakers. Since Børresen loudspeakers are developed and designed by the same people as Ansuz cables the two brands share a common DNA when it comes to sound reproduction.
• Ansuz develops and manufactures cables based on advanced, cutting-edge technologies. Ansuz cables deliver a pure signal flow that unleashes the authentic sound originally intended by the master recording. To achieve this, it is imperative to lower resistance, curb induction, and reduce noise floor to a minimum. The more advanced the cable series, the more refined and sophisticated the implemented technologies, and the more transparent, holistic, and authentic the resulting soundstage.

Ansuz Darkz resonance control

• The loudspeaker stands are prepared for using the Ansuz Darkz resonance control devices. Ansuz Darkz absorbs vibrations that are not directly related to the signal path. The absorption results in audible vibration feedback, which affects the sound quality. It is the natural and authentic sound that Ansuz Darkz devices are designed to preserve. There is no alteration of the authentic sound reproduction which, when using conventional grounding materials, often makes the sound unnaturally cold and harsh.
