Wharfedale Diamond 12.0i Bookshelf Speakers (Pair) – Black- OPEN BOX

Since its launch in 2020, the Wharfedale DIAMOND 12 Series has received widespread praise as a standard for performance and value in affordable hi-fi speakers. After over five years of consistent success, awards, and positive reviews from audio enthusiasts and critics alike, the DIAMOND 12 Series has established itself as one of the most enduring and best-selling speaker series.

Now, Wharfedale is excited to introduce the updated DIAMOND 12i Series. This new series features luxurious, modern finishes and subtle acoustic improvements that build on the strong foundation of the original design.

Incremental Acoustic Enhancements

Along with the aesthetic upgrade, Wharfedale’s engineering team revisited the speaker’s internals, paying special attention to bass port tuning and airflow control. Small but significant changes to the port design and internal damping have improved bass clarity and low-frequency control—especially in real-world environments. Listeners will notice the difference.

A thorough port design effort led by Wharfedale’s Director of Acoustic Design, Peter Comeau, and senior engineers Dan Bailey Ornellas and Oliver Davies aimed to refine low-frequency performance through extensive empirical testing and listening evaluations. The development process lasted several months and included advanced techniques, such as laser interferometry, extensive anechoic and in-room measurements, and computational fluid dynamics (CFD) to assess airflow and pressure in the port structure. Critical listening sessions—totalling hundreds of hours—were held to confirm the results. The outcome is a bass response that is better controlled and more articulate, with improved transitions between low and mid frequencies and consistent spatial performance, no matter the placement. These changes maintain the DIAMOND 12’s signature neutrality while subtly increasing listener engagement and dynamic flow.
