About the Grand Harmony

The Aurum Cantus Grand Harmony is a high-end 4.5-way vented-box floor-standing speaker designed for large listening environments. It features a complex driver array including two G2Si purified aluminum ribbon tweeters (one front, one rear), an AST2560 aero striction tweeter, a 6.5" midrange driver, and two 8" woofers. The drivers use advanced materials such as nanometer aero-metal plated carbon fiber sandwich cones and copper-clad aluminum voice coils. The crossover network employs high-quality components including M-Cap MKP capacitors and military-grade resistors. The speaker supports bi-wiring with four 18mm gold-plated copper connectors and uses Teflon insulated OCC cables internally. The cabinet is made from high-quality MDF with finishes available in Sapele Pommele, Rosewood, Cherry, and Black Piano high gloss paint. Dimensions are 1190mm x 357mm x 492mm (HWD) and each speaker weighs 61 kg (134.5 lbs). The design emphasizes detail, resolution, dynamic range, and tonal balance, with a rear-firing ribbon tweeter to enhance soundstage depth and spatiality. Recommended amplifier power is 50-350W with an impedance of 4 ohms (minimum 3.2 ohms) and sensitivity of 88dB. This speaker is considered a benchmark product in its price category,
