Engineered with audiophile-grade components — premium drivers, hand-matched crossovers, and a hardwood enclosure tuned for natural decay. Every cabinet is internally braced and damped to suppress resonance below the threshold of audibility.

• Custom 6.5" mid-bass driver with paper-pulp cone for transient accuracy.
• Soft-dome silk tweeter with neodymium motor for airy, fatigue-free highs.
• Point-to-point hand-wired crossover using silver-foil capacitors.
• Bi-wirable terminals plated in pure copper.

Place each speaker on its dedicated stand, toed-in toward the listening position. The hardwood enclosure resonates in concert with the drivers — a deliberate, musical interaction rather than a flaw to be eliminated.

Connect to a quality amplifier using bi-wired speaker cable for the most transparent presentation. Allow 50–100 hours of break-in for the drivers and crossover capacitors to settle into their final voicing.
