Marten Coltrane 3 : Speaker

The original Coltrane quickly became a classic when it was launched in 2003; in its third iteration it continues to impress. It has everything that makes a true Coltrane 3 speaker: borrowing design and technology from Supreme 2. It has all the poise and power of its counterparts, but in a lounge-friendly cabinet.

Coltrane 3 uses the bespoke crossover technique developed for Supreme 2. The first order crossover makes for absolutely perfect time and phase coherence; and flawless time coincidence.

This model upholds our philosophy of truth in music, by faithfully reproducing sound exactly as you hear it in reality.
