ArtSound UNI20 black (pack of 2)
Overview
ArtSound UNI20 is a passive two-way hi-fi speaker, designed by the Belgian manufacturer ArtSound for small spaces. Despite its compact dimensions, this on-wall speaker delivers a rich, full sound. Its enclosure with neutral lines and rounded corners gives it a discreet appearance that blends seamlessly into most interiors. Sold in pairs with a wall mount with ball joint, it meets the needs of small rooms where floor space is not an option.
The Universals range: three models, one approach
The UNI20 belongs to the Universals series, a line of speakers developed based on more than 20 years of expertise, where every detail reflects this accumulated know-how. This range includes three distinct models:
| Model | Coverage | Power | Woofer | Frequency response |
|---|---|---|---|---|
| UNI20 | < 20 m² | 10-40 W | 3” | 150 Hz - 20 kHz |
| UNI30 | < 40 m² | 20-60 W | 3” | 100 Hz - 20 kHz |
| UNI40 | < 40 m² | 20-100 W | 5.25” | 60 Hz - 20 kHz |
All of them share a clean design with an elegant front and rounded corners, as well as an exclusive mount that allows for all kinds of orientations to adapt to any décor.
UNI20 design and construction
The UNI20 uses a two-way system that splits sound reproduction between two dedicated drivers. The woofer handles low and mid frequencies, while the tweeter focuses on high frequencies. This distribution promotes better sound reproduction and increased clarity.
The bass driver uses a 3-inch fiberglass cone, paired with a 0.5-inch PEI (polyetherimide) dome tweeter. PEI tweeters are lightweight and deliver a more lively sound than silk-dome models, while being less aggressive than aluminum versions. They generally require less power than silk or aluminum dome tweeters, which matches the modest amplification range of the UNI20.
The enclosure is made of ABS, a thermoplastic material that ensures long-term durability and reliability. Dimensions remain compact (150 × 96 × 94 mm for around 750 g per speaker), allowing for discreet installation without sacrificing sound quality.
Installation and multifunctional mount
The supplied wall mount stands out for its versatility and ease of installation. Thanks to the ball joint, the speaker can be oriented in any direction, including horizontally. This flexibility is particularly useful when the speaker is mounted high up: by tilting it downwards, you optimize sound reproduction toward the listening area.
The plug-in screw terminal system makes connecting the speaker cable much easier. These compact passive speakers have an integrated mount and can be installed on a wall or ceiling, freeing up space on furniture or shelves.
Note: a replacement bracket is available separately for the UNI20 and UNI30 models, making replacements easier if needed.
Use cases and suitable environments
The UNI20 is suited for use in small areas: hallways, small kitchens, restrooms. It is also suitable for background music in various contexts, including conference rooms or churches for speech reinforcement.
These speakers are designed for indoor use only and are not waterproof. For outdoor use, ArtSound offers the ASW range, while the Happi speakers are specifically designed for bathrooms.
With an impedance of 8 ohms and a recommended power range of 10 to 40 watts, the UNI20 is compatible with most entry-level and mid-range hi-fi amplifiers. The 90 dB sensitivity allows you to achieve a proper sound level even with modest amplification.

Frequently Asked Questions
Can the UNI20 be used as a surround speaker in a home cinema system?
Yes, its compact size and adjustable mount make it a suitable candidate for the rear channels of a multichannel system. The overlap in the low frequencies with a subwoofer provides a coherent sound for movies. For larger rooms, the UNI30 or UNI40 models will be more appropriate.
What type of amplifier is needed to power the UNI20?
The UNI20 works with amplifiers delivering between 10 and 40 W per channel at 8 ohms. A standard stereo hi-fi amp, an AV receiver, or even some compact digital amplifiers are perfectly suitable. Avoid amplifiers that are too powerful, as they could damage the drivers if used at excessive levels.
What is the main difference between the UNI20 and the UNI30?
The UNI30 has a bass-reflex port, a 3-inch paper-cone woofer, and covers a wider frequency range (100 Hz–20 kHz versus 150 Hz–20 kHz for the UNI20). It is recommended for spaces up to 40 m² and supports amplifiers from 20 to 60 W. The UNI30 therefore offers more body in the lower range and is better suited to larger rooms.
Are the UNI20 speakers suitable for outdoor installation?
No, the speakers in the Universals range are not waterproof and are intended for indoor use only. For a terrace, pool, or garden, choose ArtSound’s ASW series, designed to withstand the elements.
What speaker cable should I use with the UNI20?
A standard speaker cable with a cross-section of 2 × 1.5 mm² to 2 × 2.5 mm² is suitable for typical lengths (up to 10–15 meters). The plug-in screw terminal connection accepts bare wire ends. For longer runs, choose a larger cross-section to limit losses.
