The Impression Diamond 15 is a bespoke, build-to-order design, individually specified and tuned for each customer. While it shares the same reference-grade drive units found in our flagship Impression Diamond Reference specification, every pair is carefully assembled and the crossover custom-specified to suit the system, environment, and listener preferences.

At its core is our pure diamond dome tweeter, delivering extraordinary precision and lifelike clarity. This is paired with an 8-inch Papyrus Fiber midrange unit and a 15-inch bass driver, creating a powerful yet natural presentation with scale, control, and emotional realism across the full frequency range.
