Description
A Complete 5.1 System Built Around Diamond 12i Speakers
This package gives you a full 5.1 surround system from one of Britain’s best-known speaker names. It comprises two pairs of Diamond 12.1i bookshelf speakers for the front and surround channels, a Diamond 12.Ci centre speaker and an SW-10 subwoofer, with a saving of £129.85 compared with buying them separately. The Diamond 12 Series has been praised as a standard for performance and value in affordable HiFi since 2020, and the updated 12i series adds three modern finishes plus refined bass port tuning and internal damping for clearer, better controlled bass. Klarity cones, blended from polypropylene and mica, are light, stiff and well damped, and a 25mm woven polyester dome tweeter keeps treble smooth and natural. A Linkwitz-Riley crossover with air-core inductors and a multi-layer low-resonance cabinet with spot bracing complete the design.
