AudioVector RSUB black
Overview
The RSUB Arreté subwoofer from Audiovector features a high-excursion carbon driver paired with a passive radiator, delivering bass reproduction that is both deep and precise. Its meticulous design and proprietary technologies make it an ideal partner for high-end audio systems, enhancing not only bass extension but also the overall listening quality.
Exceptional Acoustic Design
The RSUB Arreté stands out for its rigorous design, with a cabinet featuring non-parallel surfaces to limit internal resonances and standing waves. This approach, combined with the use of nanoporous damping material, ensures remarkable acoustic neutrality. The main 25.4 cm carbon fiber driver is complemented by a downward-firing passive radiator of the same size, optimizing low-frequency response while preserving speed and agility.
The laminated baffles and carbon connection plate reflect particular attention to detail. The latter eliminates interactions with the crossover components mounted behind it, ensuring a direct connection and a clearer sound. Despite its impressive performance, the RSUB Arreté maintains compact dimensions (39.1 x 38.4 x 37.6 cm), making it easy to integrate into various listening environments.
Innovative Proprietary Technologies
The Freedom Grounding® system is one of the RSUB Arreté’s major innovations. This technology connects the speaker chassis to ground via the mains power supply, significantly reducing distortion and background noise. The result is a notable improvement in soundstage depth and focus, with richer and more natural harmonics.
The 400-watt class A/B amplifier, with its cryogenically treated components, delivers controlled and musical power. Unlike the class D amplifiers often used in subwoofers for their energy efficiency, this choice prioritizes sound quality and finesse of reproduction.
The Low Compression Concept (LCC) technology allows the driver to maintain its linearity even at high volumes, while the NES (No Energy Storage) concept reduces sonic coloration. The natural crystalline structure (NCS) of the components ensures optimal signal transmission.
Seamless Integration into Any System
The RSUB Arreté stands out for its ability to integrate harmoniously into an existing audio system. More than just an addition of low frequencies, it helps to free up the midrange of the main speakers, as if they suddenly had less effort to make. This uncommon feature for a subwoofer reflects a holistic design aimed at improving the entire sound spectrum.
Its variable frequency response (18-180 Hz) allows for precise adjustment according to the associated speakers and room acoustics. Phase settings (+/- 180 degrees) also facilitate perfect integration with the rest of the system.
Multiple connection options (line-level phono and high-level Speakon) offer appreciable flexibility, allowing use with traditional amplifiers or dedicated power amplifiers.
Sound Performance: Speed and Attack
The RSUB Arreté’s sonic signature is characterized by its speed and precision. Unlike many subwoofers that focus solely on depth, this one emphasizes the musical dimension of reproduction. It delivers fast, articulate bass that never distracts from the main speakers it accompanies.
Its versatility allows it to excel in both music and film reproduction, providing the necessary impact for special effects while preserving the subtlety of musical nuances.

Frequently Asked Questions
How does the RSUB Arreté differ from other high-end subwoofers?
Its main difference lies in its ability to enhance not only the low frequencies but also midrange reproduction. Its Freedom Grounding system, non-parallel surface construction, and carbon fiber drivers are also distinctive features rarely found together in a single product.
Is it compatible with speakers from brands other than Audiovector?
Absolutely. While it integrates perfectly with Audiovector speakers such as the R1 or R3, its universal design and multiple connection options allow it to be paired with virtually any speaker. The frequency and phase adjustments make it easy to adapt to different systems.
What are the advantages of the Freedom Grounding system?
This innovative system connects the speaker chassis to ground via the mains power supply, significantly reducing distortion, improving harmonics, lowering noise levels, and increasing the depth and precision of the soundstage. It represents a significant step towards more faithful reproduction.
