Capturing the essence of the acclaimed Reference series into a simpler, elegant form, the Reference Three combines clarity and openness with a room-filling sense of atmosphere. Music is revealed with refinement and ease, making every performance both engaging and inviting More than Beryllium Due to its incredible rigidity, Beryllium represents the ultimate material for a tweeter dome. Where soft domes turn choirs into grain, hard rock into noise, Beryllium can separate the complex harmonics with ease and keep the music clean and precise, also at high listening levels. But we do not stop there. Opting for an unconventional approach, we mount the dome flush with the baffle, as opposed to the typical recessed placement, allowing the dome to unleash its wide off-axis response without obstruction—vital for achieving an expansive, open sound. This unique dome placement is a rarity, demanding meticulous baffle rounding to prevent diffraction and a more intricate crossover design. However, the resulting benefits outweigh the challenges. Complementing this design, we employ an exceptionally narrow surround to eliminate any lingering “soft dome” coloration. With a mere 0.1-gram moving mass and a magnetic flux density of 2.0 Tesla, our high frequencies reach reference-level quality. A Cellulose Glass Composite By combining cellulose with fine glass fibers, this cone material unites the best of two worlds. Cellulose brings damping qualities and warm, natural tone, while glass fibers add stiffness and control, reducing unwanted resonances. The coating process further stabilizes the cone and ensures consistent performance across the audible spectrum. Where traditional paper membranes can introduce colorations at higher levels, the Cellulose glass composite maintains neutrality and detail, even under demanding dynamics. Supporting this, a Balanced Drive motor structure minimizes distortion by keeping the voice coil motion symmetrical, ensuring clarity and precision throughout the range. This careful balance allows the woofer to deliver a smooth, natural midrange together with an articulate and well-controlled bass. The result is a driver that is both musical and precise—an ideal foundation for the Reference Three, offering an engaging, open sound with a remarkable sense of ease.
