Marten Parker Quintet Floorstanding Loudspeakers

The Marten Parker Quintet is the flagship floorstanding loudspeaker of the Parker Series, combining four custom 7.5-inch ceramic bass/midrange drivers, four rear-mounted 9-inch aluminum passive radiators and a 1-inch pure ceramic tweeter in a resonance-controlled 35 mm M-board cabinet. Its 2.5-way architecture delivers a specified 24Hz–40kHz ±2dB frequency range, 93dB sensitivity and 350-watt power rating, giving the Parker Quintet the scale and dynamics required for serious reference-level two-channel systems. Marten

Every major element—from the custom drivers and multi-diverse crossover to Jorma internal wiring, WBT Nextgen terminals and integrated Marten Isolators—is engineered as part of a complete system. The result is a large floorstanding loudspeaker designed to minimize cabinet contribution while producing deep, controlled bass, high resolution and an expansive soundstage.

Four Custom 7.5-Inch Ceramic Bass/Midrange Drivers

The Parker Quintet uses four 7.5-inch ceramic bass/midrange drivers developed specifically for the Parker platform. Marten specifies long linear excursion and powerful neodymium magnet systems to maintain control across the drivers' operating range. Marten

Using four ceramic drivers provides substantial radiating area while retaining the low mass and rigidity central to Marten's ceramic-driver philosophy. This architecture contributes to the Quintet's combination of speed, dynamic capability and 93dB/2.83V sensitivity.

Pure Ceramic Tweeter

The standard Parker Quintet uses a 1-inch pure ceramic tweeter, maintaining a consistent material philosophy with its ceramic bass/midrange drivers.

The tweeter crosses over at 2,200Hz through Marten's multi-diverse crossover architecture and extends the speaker's specified response to 40kHz. Marten

For customers seeking the highest Parker specification, this ceramic tweeter is replaced by a pure diamond unit in the separate Parker Quintet Diamond Edition.

Four 9-Inch Aluminum Passive Radiators

The rear of each Parker Quintet carries four 9-inch aluminum passive radiators. Combined with the four active ceramic bass/midrange drivers on the front, this gives each loudspeaker nine driver/radiator elements in total. Marten

The passive-radiator system extends and controls low-frequency output without relying on a conventional open bass-reflex port. Marten specifies bass extension down to 24Hz ±2dB, exceptional low-frequency reach for a passive 2.5-way loudspeaker.

Multi-Diverse Crossover Architecture

Marten developed a multi-diverse order crossover specifically for the Parker Series rather than applying a conventional standardized filter topology.

The Parker Quintet's crossover point is 2,200Hz. In the ceramic version, Marten specifies polypropylene capacitors and copper-foil inductors. Marten

The network is optimized around the acoustic behavior of the custom ceramic drivers, tweeter and cabinet so the individual elements operate as a coherent loudspeaker rather than calling attention to separate frequency bands.

35 mm M-Board Cabinet

The enclosure is constructed from 35 mm M-board, Marten's multi-layer cabinet material engineered to suppress unwanted resonance.

Its tapered form varies in width from approximately 9.4 to 13 inches, combining substantial structural mass with non-parallel geometry. Marten's objective is to reduce stored cabinet energy so the enclosure contributes as little coloration as possible to the reproduced sound. Marten

Each Parker Quintet weighs 133 pounds / 60 kg.

Jorma Internal Wiring

Internal signal wiring is supplied by fellow Swedish high-end manufacturer Jorma Design.

Marten uses separate positive and negative conductors with high-quality copper and shielding designed to preserve signal integrity between the crossover and drivers. Marten

This is another area where the standard and Diamond models differ: the standard Quintet uses Jorma internal wiring, while the Diamond Edition moves to Jorma Statement.

WBT Nextgen Single-Wire Terminals

The Parker Quintet uses a single-wire WBT Nextgen terminal configuration.

Marten intentionally specifies a single set of terminals rather than splitting the crossover into external bi-wire sections. The loudspeaker presents a 4-ohm nominal impedance with a 2.7-ohm minimum, making amplifier current capability an important consideration when building a system around the Quintet. Marten

Marten Isolators by IsoAcoustics

The mirror-polished stainless-steel base incorporates Marten Isolators, developed with IsoAcoustics specifically for Marten loudspeakers.

The isolation system is engineered to resist lateral movement and oscillation while reducing mechanical energy transfer between the loudspeaker and floor. Marten cites improved bass control, openness and clarity as benefits of reducing this mechanical interaction. Marten

The isolators are also suitable for carpeted installations.

High 93dB Sensitivity

Despite its substantial bass capability, the Parker Quintet offers a relatively high 93dB sensitivity at 2.83V.

That makes amplifier selection particularly interesting. The speaker is capable of considerable output without requiring extreme amplifier wattage, although its 2.7-ohm minimum impedance means amplification should remain stable and authoritative into low-impedance loads. Marten

This is precisely the kind of loudspeaker where amplifier quality and current delivery matter more than simply selecting the largest published wattage figure.

Piano Walnut

Piano Black
Piano White Marten

The main product webpage currently displays Piano Walnut, Matte Walnut, Piano Black and Piano White imagery, although its text specification line omits Piano White. Marten's current manual and technical-specification document explicitly include Piano White, so I would include all four in the Shopify listing. Marten

Marten Parker Quintet at The Grid HiFi

The Marten Parker Quintet deserves electronics capable of exploiting its speed, resolution, bass extension and dynamic capability. The Grid HiFi can build the complete system around the Quintet, including reference amplification, digital or analog sources, power conditioning, cabling, equipment support and precise loudspeaker placement.

Its combination of 93dB sensitivity and 2.7-ohm minimum impedance also makes professional amplifier matching particularly valuable. The objective isn't simply more power—it is choosing electronics with the control, current delivery and refinement appropriate for Marten's ceramic drivers.
