The Marten Mingus Orchestra Reference Speaker is a four-way floor standing loudspeaker built from multi-layered fibre laminate with solid wood top and bottom accents. Designed to bring the dynamics of a live orchestral performance into your listening space, each cabinet delivers transparent acoustic performance with exceptional scale, precise timing, and natural tonal balance.Pure Diamond Drivers for Crystal-Clear Highs:Upper frequencies are handled by pure diamond tweeters that deliver crisp detail without harshness or fatigue. Because diamond conducts heat rapidly and maintains supreme structural rigidity, the voice coils stay cool under heavy playback, allowing every delicate cymbal strike and high-frequency nuance to sound effortless and natural.Ceramic and Aluminum Drivers for Rich Sound:Vocal clarity and acoustic instrument textures are powered by a ceramic midrange driver that reproduces recordings with lifelike presence. The lower registers are driven by long-throw aluminum sandwich honeycomb bass units, providing deep, fast, and punchy low frequencies that fill your room without muddiness or distortion.Resonance-Free Cabinet with Precision Decoupling:The cabinet features curved side panels to eliminate internal standing waves and edge reflections, preserving a clean soundstage. Internal wiring is supplied by high-purity Jorma Design copper cables, while custom Marten isolators engineered with IsoAcoustics decouple the structure from the floor to keep low-end energy tight and articulate.Authorized Dealer:We are an authorized dealer for Marten.
