Product description
The Diamond 12.4i floorstanding speakers are designed to fill rooms with a large, controlled soundstage. Music gains scale, depth, and impact, while details remain clear and natural. The sound feels powerful and spacious, with a solid bass foundation and an open, relaxed presentation that invites extended listening.
The large enclosure features a multi-layer sandwich construction and carefully placed internal bracing to minimize resonance. Combined with refined bass port tuning and internal damping, this results in tight, deep bass and a stable soundstage, even at higher volumes. This ensures a controlled and musical presentation in any listening room.
The 150mm woofer, 150mm midrange, and 25mm dome tweeter work together with a precisely tuned 2,5-way crossover and optimized cabinet design to achieve a frequency response of 40Hz to 20kHz. This configuration delivers powerful bass, natural midrange, and clear highs, delivering music with conviction, detail, and coherence.
