The rest of the range comprises the Diamond 210 miniature standmounts, the 230, 240 and 250 floorstanders, and the 220C centre speaker. 
These promise to deliver the same cosmetic and sonic improvements as the Diamond 220s: a new cabinet construction, new lacquered baffle design, improved bass motor system and a new slot-loaded distribution port for improved airflow. They also feature upgraded crossover networks to improve integration between the drive units.
