With its innovative materials and precision-crafted components, the C1 delivers a remarkable and immersive listening experience.

Technologies and Components

Bass/midrange Drivers: Børresen DCC5 Neo

At the core of the C-Series performance is the Børresen 5-inch CC Neo bass/midrange driver, meticulously crafted to deliver superior clarity and dynamics.


The Membrane The membrane consists of three layers, laminated into a single unit: an aramid honeycomb core between two carbon fiber skins. The combination of these materials result in a moving surface with exceptional properties. Carbon fiber layers provide optimum stiffness in many different directions. This unique characteristic reduces vibrations and resonances to incredibly low levels.The Magnetic Motor System The C-Series features a sophisticated magnetic motor system with double copper caps on the pole rings. This design, adapted from higher-end Børresen drivers, minimizes electromagnetic resonance and lowers inductance, easing the load on the amplifier.


The Børresen Ribbon Tweeter: Speed and Precision

The C-Series is equipped with Børresen’s renowned RP94 Ribbon Planar Tweeter, a signature feature of the Børresen brand. With a remarkable efficiency of 94 dB and an ultra-light moving mass of just 0.01 grams, this closed ribbon tweeter is capable of incredible speed and responsiveness. Operating from 2.5 kHz and above, it captures the finest sonic details with precision and is robust enough to handle high transient peaks without distortion. This level of detail and clarity allows listeners to experience music with a level of subtlety and refinement rarely achieved.



Crossover

The Børresen C1 loudspeakers is based on serial crossover networks,which provide the same phase-locked electric current flow to transducersin the filtering region. Although this crossover topology is significantly moredifficult to implement, by diverting the out-of-band currents it creates a muchmore coherent filtering system.

C1 Stand: Perfect Synergy Between Speaker and Stand

The C1 loudspeaker stands are designed to support the Børresen C1 speakers in the best possible way by placing the speakers in the correct height and angle. The stands are made of the same robust wood composite material as the cabinets, creating the perfect synergy between speakers and stands. As the stands are without iron components any magnetically interference into the loudspeakers crossovers is avoided. The stands are equipped with Ansuz Darkz S2t Resonance Control devices, further reducing vibrations and improving sound quality. The stands can also be upgraded with additional Darkz for even greater resonance control and performance enhancement. The Børresen C1 loudspeaker represents the pinnacle of stand-mounted speaker design, combining advanced technology and meticulous craftsmanship to deliver a truly extraordinary musical experience.

Overall Score 89/100

Rating for [object Object]

Nicely Roasted

The Børresen C1 delivers exceptional air and refinement up top via its ribbon planar tweeter, pairing with a precise DCC mid/woofer for striking timbral accuracy and wide soundstage imaging. Compact but solidly built, it offers controlled bass and articulate dynamics when driven by a capable amp — praised by Audiophilepure.

Pros

  • Exceptional, airy treble and low distortion from the RP94 ribbon planar tweeter.
  • Natural, well-resolved midrange and strong timbral accuracy from the DCC driver and crossover design.
  • High-quality build and heavy, well-finished cabinets indicate premium construction and fit-and-finish.

&

Cons

  • Very high price for a bookshelf speaker, which limits value for many buyers.
  • Moderate sensitivity means a capable (>50 W) amplifier is recommended to unlock full dynamics.

Sound Quality

90/100

Bass

89/100

Single 5"-class DCC5 woofer with claimed 45Hz–50kHz response indicates unusually deep low-end extension for a small bookshelf. Sensitivity 87 dB and sealed-like cabinet dimensions imply good control and articulation; recommended amp >50 W will help bass authority. No reviewer excerpts provided—score based on manufacturer spec and driver size (small 5").

Mid

90/100

Ribbon planar tweeter plus a dedicated DCC driver suggests highly resolved, natural midrange and excellent timbral accuracy. Cabinet mass (18 kg) and high-quality finish point to careful driver/crossover integration that should preserve vocal body and clarity. Scored from specs in absence of independent reviews.

Treble

92/100

Børresen RP94 Ribbon Planar tweeter and claimed extension to 50 kHz indicate exceptional top-end extension, air and refinement with minimal harshness. Ribbon technology typically yields low distortion and airy highs; expect excellent detail retrieval and smoothness. Assessment derived from driver spec and frequency claim.

Soundstage Imaging

92/100

Planar ribbon tweeter and precision driver design normally produce focused, holographic imaging and wide perceived soundstage for the cabinet size. Physical dimensions and premium construction support stable imaging and spatial cues. Rating inferred from driver topology and brand positioning.

Dynamics

86/100

Moderate sensitivity (87 dB) but recommended amplifier >50 W suggests the C1 can deliver strong micro- and macro-dynamics when driven adequately; may need a capable amp to reach full dynamic potential. Cabinet mass and driver quality should aid transient control. Score balanced by sensitivity/amp dependence.

Build Quality

94/100

High mass (18 kg each), piano-lacquer finish options and premium Borresen drivers imply excellent cabinet construction, fit-and-finish, and likely high-quality crossover parts. The brand's reputation and stated materials justify a top-tier build score despite no teardown data. Score based on specs and finish details.

Features Connectivity

80/100

Passive bookshelf baseline applied. Single-post passive speaker (no DSP/streaming expected); no bi-wire/bi-amp or special boundary EQ reported in specs.

Value for Money

68/100

At a listed price of 16,500 (currency not specified), the C1 occupies a very high price tier for bookshelf speakers. Exceptional technical claims justify premium pricing for buyers seeking flagship bookshelf performance, but value is constrained relative to more affordable high-performance alternatives.
