Elipson Premium Sub 12 black
Overview
The Premium Sub 12 from Elipson is a subwoofer equipped with a 300 mm fiberglass-cone driver and a 500-watt Class D amplifier. It reproduces low frequencies with acoustic control suited to medium to large hi-fi and home theater setups. The sub uses a front-firing bass reflex system with an internal structure designed to optimize airflow and reduce turbulence.
A fiberglass driver for controlled reproduction
At the heart of the Premium Sub 12 is a 300 mm driver featuring a fiberglass diaphragm. This material offers an excellent stiffness-to-mass ratio for low-frequency reproduction. The cone’s light weight enables fast, precise movement, while its rigidity limits deformation during large excursions. This combination delivers an extended low-end response, reaching down to 22 Hz (±3 dB), while preserving clear transient definition.
The Class D amplifier delivers a substantial 500 watts, ensuring ample dynamic headroom even in the most demanding passages. This amplification architecture, known for its energy efficiency, generates little heat and enables stable long-term operation. The integrated digital signal processing (DSP) applies a calibrated +3 dB boost at 28 Hz, compensating for the natural roll-off in the extreme low end while maintaining overall linearity.
Auto standby optimizes power consumption when no signal is present, while the subsonic filter fixed at 23 Hz (12 dB/octave) protects the driver from potentially damaging infrasonic frequencies.
A bass-reflex design with optimized laminar flow
The key technical feature of the Premium Sub 12 is its bass-reflex loading equipped with an internal acoustic guide. This structure, positioned in the front port, regulates the airflow generated by cone movement. The internal baffle lengthens the acoustic path and ensures smooth, laminar air velocity, drastically reducing turbulence and acoustic compression typically responsible for unwanted port noise.
This approach differs from conventional circular ports that can create vortex effects at high levels. The laminar design maintains organized airflow even during large cone excursions, preserving sonic clarity in dynamic passages. The front port also facilitates placement in the listening room, avoiding the constraints of rear ports that require clearance from the wall.
The cabinet dimensions (410 x 430 x 480 mm without grille or feet) have been calculated to optimize internal volume and the resonator’s tuning frequency. This compact geometry allows easy integration in various home environments while providing the acoustic volume needed for extended low-frequency reproduction.
Connectivity and settings for flexible system integration
The rear panel of the Premium Sub 12 offers comprehensive connectivity to suit various configurations. Low-level stereo line inputs (L/R) allow connection to hi-fi amplifiers without a dedicated subwoofer output. The LFE input accepts the signal directly from home theater amplifiers with bass management. Line outputs enable daisy-chaining to a second subwoofer or sending the filtered signal back to satellite speakers.
The variable crossover from 30 to 200 Hz provides wide adjustment latitude to harmonize the transition with the main speakers. This extended range allows pairing with compact speakers that need a higher handoff, as well as with floorstanders capable of reaching lower frequencies. The phase switch (0°/180°) optimizes acoustic coupling with the main speakers based on their relative positioning in the room.
These manually adjustable parameters require careful calibration to achieve coherent integration. The absence of a remote control or automatic room correction means adjustments must be made by ear or with external measurement tools for the most meticulous users.
Position in the range and comparison with adjacent models
The Premium Sub 12 occupies the central position in Elipson’s new Premium Sub range, between the compact Sub 10 and the imposing Sub 15. This stratification addresses specific needs depending on room size and the desired sound pressure level.
The Premium Sub 10, with its 250 mm driver and 300-watt amplification, suits smaller spaces where discretion is key. Its frequency response starts at 27 Hz, sufficient for most music and movie content. Its reduced dimensions (360 x 395 x 442 mm) and modest weight (18 kg) make integration easier where space is at a premium.
The Premium Sub 15 is the high-end solution, with its large 380 mm driver and 650-watt amplification. Capable of reaching 19 Hz, it targets ambitious installations in large dedicated spaces. Its substantial dimensions (465 x 552 x 534 mm) and 41 kg weight require a dedicated, stable location. This range progression follows a coherent logic where each model finds its place based on the user’s constraints and ambitions.

Frequently Asked Questions
What’s the difference between laminar flow and a conventional bass-reflex port?
Laminar flow maintains organized, regular airflow in the port, unlike traditional circular ports that can create vortices at high volume. This design reduces unwanted chuffing and acoustic compression, preserving clarity even during intense dynamic passages.
Is the Premium Sub 12 better suited for hi-fi or home theater?
This sub adapts to both uses thanks to its extended response and flexible settings. For hi-fi, the precision of its fiberglass diaphragm and its ability to reach 22 Hz enrich musical reproduction. In home theater, its 500 watts and DSP deliver the physical impact sought for special effects and dynamic soundtracks.
Can two Premium Sub 12 units be used in the same setup?
The line outputs indeed allow chaining multiple subs. This configuration improves bass distribution in the room, reduces standing waves, and increases overall dynamic capacity. Phase and crossover settings should be harmonized between the two units for optimal coupling.
How should the Premium Sub 12 be ideally positioned in a room?
The front port offers placement flexibility, allowing the sub to be positioned closer to the rear wall if needed. The optimal position depends on the room’s acoustics, but corner placement generally reinforces bass level, while a more central position offers a flatter response. Listening tests in different locations remain the best method to determine the ideal placement.
Can the 23 Hz subsonic filter be disabled?
The technical specifications do not mention the ability to disable this filter. Fixed at 23 Hz with a 12 dB/octave slope, it protects the driver from potentially destructive infrasonic content while preserving the entirety of the audible range, as human perception of bass generally fades below 20 Hz.
