Elipson Premium Sub 10 matte black
Overview
The Premium SUB 10 from Elipson is a subwoofer equipped with a 250mm transducer featuring a fiberglass membrane and 300-watt Class D amplification. It can reproduce low frequencies down to 27 Hz. The subwoofer uses a front-firing bass reflex system with an internal acoustic guide, designed to reduce turbulence and limit sound coloration.
A concentration of advanced acoustic technologies
The heart of the Premium SUB 10 is based on a 250mm driver whose fiberglass membrane combines rigidity and lightness. This combination of mechanical characteristics allows the transducer to maintain optimal control throughout its entire excursion range, particularly in the lowest frequencies where membrane excursions become significant. Fiberglass offers a particularly favorable weight-to-rigidity ratio, limiting parasitic deformations that could alter response linearity.
The 300-watt Class D amplification provides a comfortable power reserve to control the transducer with precision. This amplification technology offers high energy efficiency, generating little heat while maintaining consistent dynamics even during demanding musical passages. The amplification module integrates a DSP (Digital Signal Processor) calibrated to subtly enhance the lowest frequencies, with a +3 dB boost centered at 30 Hz, thus compensating for the natural drop in efficiency in the extreme low end.
The front-firing laminar bass reflex loading constitutes one of the technical signatures of this subwoofer. Unlike traditional cylindrical ports, the laminar geometry features an enlarged rectangular cross-section that reduces the velocity of air passing through the port. This design drastically limits turbulence phenomena responsible for parasitic flow noise, particularly audible at high volume. The front positioning of the port considerably facilitates the subwoofer’s integration into the listening space, eliminating distance constraints relative to rear walls.
Thoughtful mechanical and acoustic design
The internal architecture of the Premium SUB 10 integrates a sophisticated acoustic guide inside the bass reflex port. This internal baffle extends the acoustic path while regulating the airflow generated by cone movements. This design, developed specifically for the new Premium range, ensures laminar air velocity, considerably reducing acoustic compressions and turbulence that constitute the main sources of distortion in conventional subwoofers.
The integrated subsonic filter, calibrated at 26 Hz with a 12 dB per octave slope, protects the transducer against potentially destructive infrasonic signals. These frequencies, inaudible but energy-hungry, can cause excessive membrane excursions. The filter acts as mechanical protection while preserving the entirety of the useful audible spectrum.
The crossover frequency adjustment range, extending from 40 to 200 Hz, offers exceptional integration latitude. This adjustment amplitude allows the subwoofer to adapt to very varied configurations, from compact satellite systems requiring high crossover points, to full-range towers where only the extreme low end needs reinforcement. The 0°/180° phase switch completes these adjustment possibilities by allowing optimization of temporal coherence with the main speakers.
Integration and practical use
The Premium SUB 10’s connectivity meets current standards with stereo RCA line inputs and a dedicated LFE input. This dual configuration allows integration in both traditional high-fidelity stereo systems and multichannel home theater installations. The line outputs enable chaining to other elements or creating multi-subwoofer configurations for large spaces.
The automatic standby system optimizes energy consumption by placing the subwoofer in rest mode after a period of inactivity. This function proves particularly practical in home theater installations where the subwoofer is only used during content rich in sound effects. Instant reactivation upon signal detection guarantees permanent availability without energy waste.
The subwoofer’s compact dimensions (360 x 395 x 442 mm with grille and feet) facilitate its placement in restricted spaces while maintaining first-class acoustic performance. The 18 kg weight testifies to the construction’s robustness, including a rigid cabinet minimizing parasitic vibrations and a properly dimensioned power transformer.

Frequently Asked Questions
What is the difference between a front-firing and rear-firing bass reflex port?
The Premium SUB 10’s front port eliminates positioning constraints relative to walls. Unlike rear ports that require minimum clearance of 15 to 30 cm to avoid turbulence and coloration, the front port allows placing the subwoofer against a wall without performance degradation. This configuration greatly simplifies integration in restricted spaces.
How does the laminar bass reflex system work?
The laminar geometry features an enlarged rectangular cross-section that decreases the velocity of air passing through the port. At equal power, air circulates more slowly than in a traditional cylindrical port, reducing turbulence that generates parasitic noise. The internal acoustic guide extends the sound wave’s path, optimizing the resonator’s tuning while maintaining regular airflow even at high volume.
Is the Premium SUB 10 suitable for a large room?
With its 300 watts and 250mm transducer, the Premium SUB 10 is ideally suited to small to medium-sized rooms up to approximately 30-35 m². For larger spaces, the Premium SUB 12 (500W, 300mm) or Premium SUB 15 (650W, 380mm) models offer superior dynamic capacity. However, the 27 Hz minimum frequency remains sufficiently low to reproduce the entire musical and cinematic spectrum.
Can two Premium SUB 10s be used together?
Using two subwoofers presents several advantages: better spatial distribution of bass, reduction of room standing wave modes, and increased overall dynamic capacity. The Premium SUB 10’s line outputs allow direct chaining of a second subwoofer. This stereo or dual-mono configuration significantly improves bass coherence in the listening space.
What is the function of the 30 Hz DSP Boost?
The digital processor applies a slight +3 dB emphasis centered on 30 Hz to compensate for the natural drop in efficiency in the extreme low end. This psychoacoustic correction enhances the sensation of depth without excessively stressing the transducer. The boost remains moderate to preserve overall linearity and avoid saturation on content rich in infra-bass.
How do you properly adjust the crossover frequency?
The setting depends on the main speakers used. For compact satellites, a crossover between 80 and 120 Hz ensures harmonious transition. With towers that naturally extend into the bass, a crossover between 40 and 60 Hz avoids frequency doubling. Ideally, acoustic measurements should be taken or, failing that, proceed by successive trials seeking the most transparent transition.
Does the subwoofer require break-in?
Like any electrodynamic transducer, the Premium SUB 10 benefits from a break-in period of approximately 20 to 30 hours of use. During this phase, the mechanical suspensions gradually soften, allowing the driver to reach optimal performance. The bass gains depth and definition after this mechanical adaptation period.
