Description

Audio Group Denmark proudly introduces the Børresen Bass Module 2—an advanced low-frequency system that brings the folded dipole philosophy of the flagship BM3 into a more compact and accessible form.

Designed and handcrafted in Aalborg, Denmark, the BM2 has been developed to complement high-performance loudspeaker systems with bass that is fast, precise, controlled, and naturally integrated. Rather than simply increasing low-frequency output, the BM2 is engineered to preserve timing, coherence, and musical flow while avoiding many of the acoustic compromises commonly associated with conventional subwoofers.

Compact, visually restrained, and acoustically sophisticated, the BM2 extends the low-frequency capabilities of a wide range of stereo systems while remaining unmistakably Børresen in both design and engineering philosophy.

FOLDED DIPOLE TECHNOLOGY IN A MORE COMPACT FORM

Audio Group Denmark proudly introduces the Børresen Bass Module 2, or BM2.

Earlier in 2026, Børresen introduced the BM3. Now, the BM2 brings the same core ideas into a smaller design.

The BM2 uses Børresen’s folded dipole technology. As a result, it delivers fast, precise, and natural bass.

However, the BM2 does more than add low-frequency output. It also helps preserve timing, clarity, and musical flow.

Therefore, the bass blends naturally with the main loudspeakers. It supports the music instead of drawing attention to itself.

Børresen develops and handcrafts its products in Aalborg, Denmark.

RARE FOLDED DIPOLE ARCHITECTURE

The BM2 uses Børresen’s folded dipole design.

Traditional sealed and ported subwoofers pressurize the cabinet. They also pressurize the listening room.

As a result, they can increase room interaction. They may also create heavy or uneven bass.

In contrast, the folded dipole design works without normal enclosure pressurization. Therefore, it reduces many common bass problems.

The design also lowers unwanted room interaction. As a result, the bass sounds cleaner and more controlled.

In addition, the front and rear sound waves have opposite polarity. This creates useful cancellation in the room.

Therefore, the BM2 can reduce excess bass energy. It can also integrate more easily with the listening space.

The result is fast and clear bass. At the same time, the sound remains powerful and natural.

A MORE COMPACT DESIGN

The BM2 brings folded dipole technology into a smaller cabinet.

However, creating the smaller design was not easy. Børresen had to fit the BM3 concept into a much tighter space.

In addition, the company used fewer but larger drivers. Therefore, the entire internal structure required careful development.

Still, the final design keeps the main benefits of the folded dipole principle.

As a result, the BM2 can fit into more rooms and audio systems. It also offers the technology at a more accessible price.

Michael Børresen explained that the process was difficult. However, he also said that the final result made the work worthwhile.

SUPERIOR BASS PERFORMANCE

The BM2 uses two 10-inch drivers.

These drivers work inside the folded dipole structure. Together, they produce deep and powerful bass.

However, power was not the only goal. Børresen also focused on speed and control.

Therefore, the drivers respond quickly to changes in the music. Bass notes start and stop with greater accuracy.

As a result, listeners can hear more texture and detail. Rhythms also sound clearer and more natural.

The BM2 adds depth and scale to the system. At the same time, it preserves the character of the main loudspeakers.

Therefore, the bass does not sound separate. Instead, it becomes part of the complete musical performance.

KEY TECHNOLOGIES

TWO CUSTOM 10-INCH DRIVERS

The BM2 features two custom 10-inch drivers.

The larger size helps produce strong low-frequency output. However, the drivers also maintain speed and control.

They move enough air to create weight and impact. At the same time, they respond quickly to the music.

As a result, the BM2 can reproduce both deep bass and fine detail.

For example, it can capture the force of a bass drum. It can also reveal the pitch and texture of an acoustic bass.

Therefore, the BM2 delivers bass with both authority and clarity.

INTEGRATED CLASS-D AMPLIFICATION

The BM2 includes integrated Class-D amplification.

Therefore, it does not require a separate power amplifier. This makes setup easier.

The internal amplifier powers the two drivers. It also controls their movement.

As a result, the BM2 can respond quickly to musical changes.

Class-D amplification also offers high efficiency. Therefore, it can deliver strong power without a large amplifier section.

During quiet passages, the amplifier preserves low-level detail. During louder passages, it provides the needed power and control.

As a result, the BM2 can handle a wide range of music.

FULLY ANALOG CROSSOVER

The BM2 includes a fully analog crossover.

The crossover controls the frequencies that the BM2 reproduces. It sends the lowest frequencies to the bass module.

Meanwhile, the main loudspeakers continue to reproduce the rest of the music.

Therefore, the BM2 can blend more smoothly with the loudspeakers.

Many active subwoofers use digital processing. However, digital systems can add signal delay.

In contrast, the BM2 uses an analog crossover. As a result, it helps preserve timing and musical flow.

The crossover also supports many system types. Therefore, users can match the BM2 with a wide range of loudspeakers.

Careful setup remains important. However, the flexible design makes natural integration easier.

NATURAL ROOM INTEGRATION

Room acoustics strongly affect bass performance.

For example, low frequencies can collect near walls and corners. As a result, the bass may sound slow or excessive.

The BM2’s folded dipole design helps reduce this problem.

It creates less room pressurization than many sealed or ported systems. Therefore, it can reduce unwanted bass buildup.

In addition, the design can make placement easier.

However, users should still position and adjust the BM2 with care. Every room has different acoustic conditions.

When setup is correct, the BM2 should not sound like a separate subwoofer.

Instead, the whole system should sound deeper and more complete. At the same time, it should remain clear and balanced.

SPEED, PRECISION, AND MUSICAL FLOW

Børresen did not design the BM2 only for more bass.

Instead, the company focused on speed, precision, and natural integration.

Fast bass helps preserve rhythm. Therefore, the music sounds more lively and engaging.

Precise bass also improves clarity. As a result, low frequencies do not cover voices or instruments.

In addition, natural integration creates a more complete soundstage. The bass supports the performance without pulling attention away from it.

Therefore, the BM2 adds impact while preserving musical balance.

DESIGNED FOR MANY AUDIO SYSTEMS

The BM2 can work with a wide range of loudspeakers.

Its integrated amplifier makes connection easier. In addition, its analog crossover supports careful system matching.

The folded dipole structure also reduces many common room problems.

Therefore, the BM2 can suit both compact rooms and larger listening spaces.

The main goal remains the same. The BM2 should extend the bass without changing the sound of the main loudspeakers.

As a result, the system gains greater scale and realism. At the same time, it keeps its original speed and clarity.

DANISH DEVELOPMENT AND CRAFTSMANSHIP

The BM2 was developed at Audio Group Denmark’s headquarters in Aalborg, Denmark, where the company designs and handcrafts ultra-high-end products across the complete audio chain.

Its compact dimensions and understated matte-black finish allow it to integrate discreetly into a listening room while maintaining the refined visual identity associated with Børresen products.

Every aspect of the BM2—from its folded dipole structure and custom driver configuration to its amplification, crossover, power supply, and mechanical grounding—has been developed as part of a complete low-frequency system.
