The Planet M from Elipson is a spherical speaker measuring 15 cm in diameter. It follows in the tradition of Elipson’s round speakers and incorporates recent technologies to produce quality sound in a compact format. It features a 10 cm 2-way coaxial driver and a white lacquered finish. This speaker can be used in both stereo setups and multichannel home theater systems.
Design and French acoustic heritage
The Elipson Planet M follows directly in the illustrious French acoustic tradition established by Joseph Léon in 1938. This ultra-compact speaker has its roots in the iconic models that marked hi-fi history, notably the legendary BS50 from 1953 and the AS-30 from 1969, found in ORTF studios and French cultural institutions.
The spherical shape is more than an aesthetic choice: it embodies a fundamental acoustic principle developed by Elipson for over 70 years. This perfect geometry eliminates unwanted resonances generated by the parallel walls of traditional speakers. Sound waves travel smoothly along the curved internal surface, avoiding harmful reflections that interfere with the cone. This design allows the driver to perform under optimal conditions, without coloration or harshness.
Acoustic configuration and technical choices
The Elipson Planet M adopts a particularly well-considered 2-way sealed enclosure design. The 10 cm coaxial driver forms the heart of this design: its treated paper cone reproduces the midrange and upper bass, while the centrally positioned 20 mm fabric dome tweeter handles high frequencies up to 22 kHz.
This coaxial configuration offers a major advantage: it concentrates sound emission at a single point, creating perfect time coherence between the different frequency ranges. The soundstage gains precision and uniformity, with a particularly stable and natural stereo image.
The sealed enclosure chosen for this Planet M reflects a specific acoustic philosophy. Rather than forcing a 10 cm driver to extend artificially into the bass at the expense of quality, Elipson has deliberately limited the frequency response to start at 90 Hz. This approach ensures faithful, controlled reproduction of the upper bass, midrange and treble, without compression or distortion.
The internal wiring deserves particular attention: 99.99% pure OFC (Oxygen Free Copper) conductors ensure unaltered signal transmission. The silver-plated binding posts, although supporting single-wiring only, provide quality connections suited to amplifiers rated from 30 to 80 watts.
Sound performance and musical character
Listening to the Planet M quickly reveals the qualities that have built Elipson’s reputation. Its musical character becomes apparent from the opening bars: timbres sound neutral and silky, free from any harshness or artificial coloration. The particularly refined midrange reproduces voices with striking naturalness, while the treble brings precise detail without ever becoming intrusive.
This speaker’s exceptional time coherence translates into a remarkably stable and precise soundstage. Instruments are positioned with a clarity that makes each source easy to identify, creating astonishing soundstage depth and width for a driver of this size.
This Planet M particularly excels at reproducing acoustic genres: jazz, classical chamber music, folk and popular music find an ideal setting here. The subtle dynamic nuances and accurate timbres allow extended listening without fatigue.
However, a subwoofer becomes essential for reproducing the full musical spectrum. Elipson’s Planet Sub, specially developed to accompany the Planet M, ensures a smooth transition around 90–100 Hz, naturally extending the bass without altering the system’s overall tonal balance.
Installation versatility and integration
The Planet M’s compact size is one of its major strengths. Measuring 15 cm in diameter and weighing just 1.7 kg, it fits into any space, from the smallest to the most spacious. The included circular base allows stable positioning on any flat surface, while optional wall and ceiling mounts open up new installation possibilities.
This installation versatility proves particularly valuable in home theater setups. The Planet M speakers can serve as surround, center or even main speakers, depending on the room size and desired configuration. Their uniform directivity and balanced response make integration into demanding multichannel systems easier.
This speaker’s sealed enclosure allows placement close to walls without harmful proximity effects. This feature greatly simplifies installation, which is particularly welcome in confined spaces where every centimeter counts.
Build quality and finishes
The Elipson Planet M demonstrates French manufacturing excellence. Each unit undergoes rigorous quality control that is evident from the moment it is handled: its solidity and assembly precision inspire confidence in its durability.
The spherical shell, made using Elipson’s traditional techniques, is perfectly uniform. The wall thickness, calculated to optimize internal damping, contributes to the overall acoustic neutrality. The gloss lacquer, applied in several coats, offers remarkable depth and shine.
The internal components reveal the same attention to detail. The coaxial driver, specially developed for this application, incorporates premium materials: a treated paper cone for its damping properties, a fabric dome for smooth treble, and a vented voice coil for power handling.
The packaging itself reflects the care devoted to the product: each Planet M comes with white gloves to prevent marks during handling, a detail that reveals the attention paid to the product’s presentation and protection.
Innovation and exclusive technologies
While retaining Elipson’s historic aesthetic codes, the Planet M incorporates contemporary technical innovations. The coaxial driver benefits from the latest advances in materials and geometry, optimizing frequency response and distortion.
The sealed enclosure undergoes extensive acoustic modeling, with an internal volume calculated to the nearest milliliter to optimize transient response. Precisely calibrated internal damping eliminates unwanted resonances without stifling dynamics.
The base design also deserves a mention: its geometry prevents contact resonances while ensuring perfect stability. Rubber inserts dampen vibrations and protect supporting surfaces.
This modern technological approach, combined with Elipson’s traditional expertise, positions the Planet M as a successful synthesis of heritage and innovation, preserving the brand’s musical soul while meeting contemporary demands.
Is it necessary to pair the Planet M with a subwoofer?
+
For a full musical listening experience, adding a subwoofer is highly recommended. The Planet M extends down to 90 Hz, perfectly covering upper bass, midrange and treble frequencies. Elipson’s Planet Sub, developed specifically for this range, ensures a smooth transition and ideally complements the low-frequency range. For listening focused on vocals and acoustic music, however, the Planet M can also be used on its own.
What amplifier power is best suited for this speaker?
+
Elipson recommends 30 to 80 watts of power to optimally drive the Planet M. This range allows you to fully exploit the speaker’s dynamic capabilities without risk of distortion. A quality 40–50 watt amplifier is generally ideal for most home listening setups.
How does the Planet M compare to the [Planet L](/p/6594-elipson-planet-l-blanc-laque)?
+
The Planet M is the ultra-compact version of the Planet L. It uses the same acoustic principles (spherical enclosure, coaxial speaker) in a format 50% smaller. The Planet L offers bass extension down to 48 Hz and is suited to larger rooms, while the Planet M prioritizes discretion and requires a subwoofer for bass. The choice essentially depends on the available space and the desired configuration.
What other finishes are available for the Planet M?
+
In addition to gloss white, the Planet M is available in several finishes: gloss black, gloss red, gloss gold, as well as the matte Mercury Ice, Neptune Stone and Saturn Dust finishes. These various options make it possible to adapt its aesthetics to any interior, from the most classic to the most contemporary.
Can the Planet M be used as a [center speaker](/categories/420-enceintes-centrales) in a home theater system?
+
Absolutely. Its coaxial design and balanced response make it an excellent center speaker. Its compact size makes it easy to integrate beneath a screen, while its neutrality ensures faithful dialogue reproduction. In a 5.1 configuration, its consistency with the other Planet M speakers guarantees optimal acoustic coherence across all channels.
What type of [wall mount](/p/10194-elipson-support-mural-pour-planet-m) is best suited for this speaker?
+
Elipson offers a dedicated wall mount (Wall Mount) specially designed for the Planet M. This mount allows optimal positioning while preserving the speaker’s spherical aesthetic. It ensures secure mounting and offers adjustment options to optimize directivity according to the listening setup.

Used as surround back speakers, they lack a bit of power in the context of my setup; I need to recalibrate all the speakers to find a better balance (11-1-4). Otherwise, the Planet M integrate well into the room, hanging from the exposed beams. The sound is clean, clear, with good presence in the highs and mids; the bass is too light, which is normal for small speakers.

Utilisé en surround back, manque un peu de puissance dans le contexte de mon installation, je dois recalibrer l'ensemble des enceintes pour trouver un meilleur équilibre (11-1-4)
Sinon les Planet M s’intègre bien dans la salle, suspendues sur les colombages.
Le son est propre, net, aigu et médium bien présent, les grave trop léger, normal petite enceinte.
