Marten Mingus Septet
The Marten Mingus Septet is an advanced 4-way floorstanding loudspeaker featuring seven drivers and representing the culmination of four years of research and development. Introduced in 2023 and handcrafted in Gothenburg, Sweden, the Septet combines custom diamond and beryllium drivers with Marten's signature first-order crossover to deliver reference-level performance in a room-friendly format.
Position in the Marten Lineup
The Mingus Septet sits at the top of the Mingus series, positioned below only the flagship Coltrane collection and the massive Mingus Orchestra. It represents a significant advancement for the Mingus range, being the first model in the series to feature custom-designed diamond and beryllium drivers developed specifically for this application. The Septet brings much of the technology from the flagship Coltrane models into a more accessible package while maintaining genuine full-range capability.
Driver Configuration
The Mingus Septet employs seven drivers in a sophisticated 4-way configuration:
A custom 1-inch pure diamond tweeter handles frequencies above 6,000Hz. Diamond's extreme rigidity enables distortion-free reproduction even at high volumes, while its thermal conductivity allows operation at high power levels without overheating.
A custom 3-inch beryllium dome driver covers the high-midrange from 800Hz to 6,000Hz. Beryllium's combination of stiffness, low mass, and high damping provides fast transient response and exceptional clarity through the presence region.
A 7-inch ceramic "sapphire" mid-bass driver handles 200Hz to 800Hz. The refined electrochemical process used to create these domes results in high internal damping and minimal distortion.
Two 8-inch aluminum sandwich honeycomb woofers cover the bass frequencies below 200Hz, featuring long excursion and hidden surrounds for low distortion.
Two 10-inch passive aluminum sandwich radiators on the rear panel augment bass response, providing fuller, more rounded low-frequency reproduction similar to the larger Mingus Orchestra.
First-Order Crossover
The Mingus Septet employs Marten's signature first-order crossover with points at 200Hz, 800Hz, and 6,000Hz. This topology ensures perfect time and phase coherence across all four frequency bands. The wide 800Hz-6,000Hz range assigned to the beryllium driver is unusual, effectively splitting traditional midrange duties across two specialized drivers for optimized performance in each band.
Cabinet Construction
The tapered cabinet is constructed from 25-40mm fibreboard laminate with advanced damping materials, internal bracing, and a 4mm aluminum plate for rigidity. Solid wood tops and bottoms in walnut, oak, or zebrano (or optional piano lacquer finishes in Black, Grey, Plum, Red, or Gold) provide both resonance control and visual customization options. Each cabinet is hand-finished with seven layers of lacquer, each polished between coats.
Marten Isolators on mirror-polished stainless steel outriggers decouple the cabinet from the floor. Four casters are supplied for positioning, replaced with isolators once the optimal location is determined.
Bass Adjustment
A four-position bass control allows adjustment for different room acoustics, enabling the Septet to perform optimally in a wide range of environments.
Standard vs. Statement Edition
The Mingus Septet is available in two configurations: Standard and Statement Edition.
Standard Edition
The Standard edition features premium crossover components and Jorma Design internal wiring, delivering the full Mingus Septet performance with exceptional clarity and dynamic capability.
Statement Edition
The Statement Edition upgrades to Jorma Statement internal cables and higher-grade crossover components. This configuration maximizes resolution, transparency, and refinement for the most demanding listeners.
Performance Characteristics
With 88-89dB sensitivity and a nominal 6-ohm impedance (minimum 2.7 ohms), the Mingus Septet requires quality amplification capable of driving moderate impedance dips. Power handling is 300 watts. The frequency response of 23Hz to 40kHz (±2dB) provides true full-range performance with bass extension that competes with dedicated subwoofers.
Summary
The Marten Mingus Septet represents a milestone in the Mingus series, combining custom diamond and beryllium drivers with ceramic mid-bass and aluminum sandwich woofers in a sophisticated 4-way design. The first-order crossover ensures time-coherent reproduction across the full bandwidth. The Statement Edition upgrade provides ultimate refinement. At 95kg per speaker, the Mingus Septet delivers commanding authority and dynamic scale while remaining practical for dedicated listening rooms. The Marten Mingus Septet establishes a new reference point for the Mingus series.
