Grande Réserve is the highest mark of distinction in French Cognac and Champagne — a title reserved for the rarest and finest. In the same spirit, ATALANTE Grande Réserve represents our most elevated creation, crafted in a single run of 300 pairs worldwide. Evolving the benchmark set by ATALANTE 7 Évo, it is conceived for listeners who seek the reference-grade performance in refined proportions, embodying both heritage and evolution within the ATALANTE family. With the debut of the RASC™ Évo tweeter and midrange, the re-engineered 12-inch BSC™ Grande Réserve woofer, and the StrataBaffle™ multi-layer front baffle, it advances acoustic precision to new heights. A refined cabinet construction, dedicated wood stand, premium components — Mundorf, WBT, van den Hul Skyline — preserve purity and control throughout the signal path. The result is balanced, articulate bass, crystal-clear detail, and an effortless musical flow—delivering the scale of a true flagship in spaces where proportion and performance matter equally. StrataBaffle™ Multi-Layer Front Baffle Engineered exclusively for ATALANTE Grande Réserve, the StrataBaffle™ front baffle combines a 6kg, 25mm extra-thick wood layer, a UDF core, and a precision structural backing. With chamfered edges, it achieves higher rigidity, lower resonance, and acoustic refinement—making every pair unique and visually timeless. 25mm Oak Wood Outer Layer, weighted 6kg: Extra-thick oak adds elegance and rigidity, reducing vibration for cleaner transients and natural sound. Ultra-Density Fibreboard (UDF) Core: Provides strength and damping, minimizing resonance for greater clarity. Engineered Structural Backing: Balances density and stability for optimal driver mounting. Acoustics Chamfered Edges: Sculpted design that reduces diffraction while adding distinctive elegance. Resonance-Free Performance: Multilayer synergy delivers greater accuracy, clarity, and composure. 12-Inch BSC™ Grande Réserve Woofer Building on the already outstanding 12-inch woofer of ATALANTE 5, the BSC™ Grande Réserve Woofer takes low-frequency performance to the next level. Delivering deeper, more extended, and articulate bass. Extended 10mm Linear Excursion & High-Roll Surround: 45% oneway X-max to ±12 mm for deeper, distortion-free bass at higher dynamics. Oversized 2.25-Inch Voice Coil: Enhances power handling, transient response, and long-term stability. Upgraded Magnet System: 29% thicker stack to 36 mm, and a supreme grade magnet, delivering stronger BL and tighter control. Doubled-layer Voice Coil Design: Now equipped 4-layer voice coil with thicker gauge high temperature wire, and Black Aluminium Bobbin former for improved cooling and long-term stability. Lower Resonance Frequency: Fs reduced by 5 Hz while maintaining SPL, balancing low-end extension, accuracy, and efficiency. Basalt Sandwich Construction (BSC) Technology: Made from lava stone, Basalt is naturally rigid yet lightweight—superior Young modulus, balancing rigidity and damping for tight, distortion-free bass. RASC™ Évo Tweeter Through massive engineering efforts, designed for exceptional clarity, precision, and effortless detail, the RASC™ Évo Tweeter delivers an extended, natural treble free from harshness and fatigue. Patented ARID Technology: Enhanced in the Évo version, the Anti Resonance Inner Dome now absorbs 97% of internal resonance, eliminating distortion for cleaner, more accurate highs Neodymium Magnet System: 5dB sensitivity, boosting dynamics, efficiency, and control Specially-Made Tetoron Dome: Custom-coated for smoother response and fatigue-free, natural treble Pure Aluminum Voice Coil: Enhances detail retrieval and precision with ultra-low inductance Aluminum Back Chamber: Lowers resonance, improves cooling, and ensures an open, transparent sound Ventilated Back Plate & Diffuser: Optimized airflow for smooth, effortless high-frequency performance RASC™ Évo Midrange Delivering unmatched transparency, tonal purity, and balance, the RASC™ Évo Midrange brings every musical detail with exceptional clarity, depth, and realism. Patented ARID Technology: Enhanced performance in the Évo version. Absorbs 96% of internal resonance, eliminating unwanted reflections for a smoother, distortion-free response. Neodymium Magnet System: A powerful high-BL motor increases sensitivity and control, enabling a dynamic and expressive midrange with effortless projection. Double Suspension Dome: A dual-suspension system ensures linear movement across all frequencies, reducing distortion, and improving clarity and articulation. Aluminum Back Chamber & Tri-Zone Resonance Control: Absorbs unwanted energy, minimises internal resonance & improves cooling efficiency. Copper-Clad Aluminum Wire & Shorting Ring: Lowers distortion, enhances transient response, and improves micro-dynamics. Ventilated Back Plate & Diffuser: Enhances airflow, reduces compression for effortless, immersive sound reproduction. Grande Réserve Cabinet & Stand Re-engineered through hundreds of hours of simulation and testing, the ATALANTE Grande Réserve cabinet achieves one of our most resonance-free constructions to date, paired with an oak wood stand reinforced by die-cast support for natural damping and superior rigidity. Resonance-Optimized Cabinet: Optimized through extensive simulation and testing for near-damp-free performance and structural integrity. Decoupling Spikes Between Cabinet & Stand: Full isolation from vibration transfer, preserving clarity and detail. Micro-Adjustable Isolation Stand: Precision spikes with premium isolation pads for levelling and eliminating external vibrations. Hybrid Stand Construction: Oak wood structure with die-cast reinforcement, combining natural damping with superior rigidity. ATALANTE Grande Réserve Crossover Designed with world-class components and artisan precision, the ATALANTE Grande Réserve crossover ensures seamless driver integration, tonal purity, and enduring reliability. Mundorf Supreme Components & WBT Binding Posts: Premium capacitors & resistors for ultimate clarity and refinement. Industry-leading connectors guarantee secure, lossless signal flow. Custom Revival Audio Parts & Supreme Air Coils: Proprietary capacitors, inductors, oversized coils engineered for natural, uncolored sound and signature tonal balance.
