Wharfedale Diamond 12i - The Next Generation of Popular Speakers
02.01.2026 07:15 | ~1 minute read
Wharfedale has updated its speaker series, introducing the Diamond 12i generation. Wharfedale claims manufacturing modernization since 2020 has enabled improved sound quality across the range. Engineers focused on bass-reflex port tuning and internal airflow, utilizing modern development methods including Computational Fluid Dynamics (CFD) and laser interferometry.
The Diamond 12i models benefit from tighter manufacturing tolerances for drivers and improved cabinet construction using MDF panels of varying thicknesses with computer-calculated internal bracing for resonance control. Like the previous Diamond 12, the new models use drivers with proprietary Klarity cones - a polypropylene and mica composite. The added mica increases cone rigidity, reducing flex and achieving low coloration.
All models feature a 25 mm polyester soft-dome tweeter mounted in a small waveguide for wide dispersion. The crossover continues using Linkwitz-Riley filters with air-core inductors chosen to minimize distortion. US prices range from $399 for the Diamond 12.0i to $1,499 for the Diamond 12.4i.
