"...what we can say with confidence is that, for their price, these are truly exceptional speakers that deliver remarkably coherent sound reproduction, both in terms of tonal accuracy and, above all, dynamics. It's rare to hear such a small speaker produce such a convincingly full-scale sound."
Our passion for music, sound reproduction, audio engineering, and elegant aesthetic design inspires every step in the creation of our products. Since 2002, with the launch of our very first speaker, the “SIROCCO,” followed in 2007 by the “SIROCCO SERIES,” this name of a warm and powerful wind has symbolized our commitment: to offer speakers with high performance-to-price ratios while making them accessible to many people.
This new "2024" series continues the legacy of the line by retaining the iconic "SIROCCO" name. However, drawing on over 25 years of experience and leveraging all our engineering and production tools, we have completely redesigned its concept: brand-new drivers, new enclosures, new crossovers, and a new advanced design—all with the sole aim of significantly enhancing the technical and musical performance of our speakers in this price range. These advancements are designed to ensure exemplary performance in terms of linearity, dynamics, reduced distortion, and power handling, with the primary goal of immersing the listener in intense and unique musical emotions.

After approximately 6,000 cumulative hours of research and development, mechanical and electronic prototyping, card debugging, programming with the development of exclusive processing, testing, and measuring (electrical, acoustic, mechanical, and thermal), we are pleased and proud to present our ATOHM RS700 power amplifier.
This highly innovative and resolutely "hi-fi" power amplifier is based on a "dual mono" structure controlled by a high-performance analog/digital card integrating a DSP. Its signal processing capabilities are used to drive the power stages (limiting, soft clipping, phase and amplitude correction, etc.) but also and above all to offer advanced coupling of this amplifier with speakers through exclusive processing based, among other things, on our knowledge of electroacoustics and, ultimately, on the exact specifications of our coupled driver units & enclosures.
The culmination of such a project requires a very significant amount of expertise in many fields. We have largely favored French partners for development as well as for the manufacturing of parts and cards. Thus, the design of the main cards (DSP) and ventilation is the result of a close technical partnership with SOLEDGE, specialized in the design of audio-digital circuits. The production of these "SMD" cards is then entrusted to a highly qualified French Alsatian company with exceptional machinery. The sheet metal work, just as technical, is also carried out in France. In the end, this unit is entirely assembled, wired, tested, and programmed in our workshops.
The device's topology, vast programming and digital chaining possibilities make the ATOHM RS700 base very versatile. We have thus developed a version totally dedicated to WATERFALL AUDIO. Other specific versions for dedicated applications will therefore be gradually introduced.
In this first ATOHM "RS700 GT EDITION" opus, we offer a power unit operating in 4 modes. The first mode allows driving any type of speaker with (high)power, dynamism, finesse, and precision. The U-GUARD processing limits the power stages just before they saturate and provides smooth clipping. Just like for the other 3 modes, this first setup allows, if necessary, filtering (digitally) the speakers in "high pass" in order to truly relieve them in the bass and to associate one or two subwoofers to relay them in the lower spectrum.
The other three modes are specific to each model of our GT SERIES speakers. Amplification and speakers then function in symbiosis. The exclusive X-GUARD™, T-GUARD™, U-GUARD™, and X-TEND™ processing come into play, allowing to increase the performance of our speakers in order to get the ultimate quintessence out of them. Consequently, they ensure unparalleled operation, even when reproducing musical tracks with sometimes explosive dynamics!
RS 700 GT EDITION - ATOHM
Specialized in designing and manufacturing high-end driver units and acoustic speakers, ATOHM has also been designing and offering high-performance amplifier modules for subwoofers for many years. Significant consecutive studies have been conducted on components, schematics, implementation topology, general construction, thermal behavior, and reliability. Thanks to our expertise in electro-acoustics, these studies take into account the actual behavior of speakers and their limits. Our exclusive X-GUARD™ technology ensures that the excursions of bass drivers never exceed an absolute limit at the lowest frequencies.
For over 10 years, our modules have been equipped with ICE POWER® power and supply stages. These ensure flawless power output. With exceptional current capabilities and very high damping factors, they are capable of powering any type of speaker. Combined with our exclusive U-GUARD™ technology, these stages provide smooth clipping and remain protected from any massive saturation.
ATOHM modules offer a purely analog signal processing that is designed to perfect the coupling of the woofer(s) with their load and to exploit all the dynamics without abrupt tonal changes or suspicious behavior when the system reaches its limits. Devoid of subsonic filters and latency, the adjustable dual low-pass filters allow for an ideal acoustic summation with any type of speaker. ATOHM modules offer a wide range of settings and connections to meet all audiophile Hi-Fi and home theater applications.
In these latest MK2 versions, we have prioritized French partners for the development and manufacturing of our CMS circuits and various parts. Ultimately, each unit is fully assembled, wired, and tested in our workshops, ensuring optimal quality.
High-quality technical and musical performances in a minimalist footprint.
