Pros and cons
Adds an extra dimension to films, series and games. Can be used as surround speakers or as height channels on top of floorstanders. Internal damping limits resonance during dynamic effects.
Correct positioning is necessary for the optimal surround effect.
Product description
The Diamond 12.3Di surround speakers add extra height and spaciousness to movies, TV shows, and games. They create an immersive soundstage above and around the listening position, allowing effects and ambient sounds to move naturally through the room. Whether used as surround speakers or placed on top of floorstanders, the soundstage gains noticeably more depth and realism.
The compact cabinet is designed for flexible placement and utilizes a solid construction with internal damping to reduce resonance. This keeps the sound tight and controlled, even with dynamic surround effects. The shape and tuning ensure wide dispersion, so the sound spreads evenly throughout the room.
The 100mm mid/woofer and 25mm dome tweeter work together with a carefully matched crossover and cabinet to deliver a frequency response of 110Hz to 20kHz. This configuration delivers clear effects, distinct detail, and seamless integration with other Diamond 12i speakers, for a convincing and cohesive surround experience.
