About the 45
The Adona Corporation 45 Series is a classic, high-performance audio rack designed for serious audiophiles. It features a unique X-frame design that provides exceptional strength and resistance to torsional flexing, far exceeding most other frame designs. The rack uses massive extruded aluminum columns weighing nearly two pounds per linear foot, which transmit vibration energy down to the floor for effective damping. The shelves are made of genuine granite bonded to anti-resonant substrates, eliminating resonant waves and providing outstanding vibration rejection. The rack includes infinitely adjustable shelves with tremendous load capacity (300 pounds per shelf), and platforms trimmed in solid cherry, maple, or black ash are available. The design incorporates a central pivot yoke with tungsten carbide ball bearings to maintain level shelving even on uneven floors, and the frames act like a well-damped spring suspension system to absorb vertical motion. The rack is modular, expandable vertically and horizontally, and compatible with other 45 Series components. Dimensions and platform sizes vary by model, with typical shelf sizes of 18"x18" and larger top shelves of 21"x27" or 19"x24" available. The rack is finished with options for black or silver aluminum columns and includes spiking or floor discs for stability. It has been in production since 2001 with a consistent design and a reputation for flat sonic signature, life-like soundstage, and tight bass response without coloration.
