ArtSound FL502BT (pack of 2)
Specifications and features
Overview
The FL502BT in-wall speakers from ArtSound combine ultra-minimal architectural integration with the latest wireless audio streaming technologies. This pair of speakers, consisting of one active unit and one passive unit, turns any space into a connected listening area without compromising your interior design.
Technical design serving acoustic versatility
The FL502BT system is built around a particularly well-thought-out two-way coaxial configuration. The 13.3 cm polypropylene-carbon composite woofer handles low and mid frequencies, while a 1.3 cm polycarbonate tweeter, positioned in the center, manages the highs. This coaxial architecture ensures even sound dispersion and outstanding time alignment between the different frequency ranges.
The frequency response extends from 65 Hz to 20 kHz, thus covering the essential audible spectrum, with a sensitivity of 88 dB that ensures dynamic reproduction even at moderate volumes. The 8-ohm impedance guarantees universal compatibility, while the class D built-in amplifier delivers 45 watts RMS per channel, offering more than enough power to cover spaces up to 50 m².
The robust ABS chassis incorporates a metal grille that protects the drivers while preserving acoustic transparency. This grille can be painted, making it easy to perfectly match the speakers to your interior décor.
Architectural integration pushed to the extreme
The frame of the Flat speakers is just one millimeter thick and four millimeters wide, setting a new standard for visual discretion. This exceptional slimness allows the FL502BT to virtually disappear once installed, leaving only an ultra-flat grille visible, blending seamlessly into the ceiling or wall surface.
The installation system revolutionizes how in-wall speakers are mounted. The self-locking clamps greatly simplify fitting, while the magnetic grille snaps into place with a single click. This approach eliminates visible screws and makes access for maintenance or cleaning much easier. Standardized cutout dimensions (180 mm diameter) and a mounting depth of only 70 mm allow installation in most existing partitions and suspended ceilings.
The option to paint the grille provides valuable decorative flexibility. Users can precisely match the speakers’ color to their environment, whether it’s a pure white for a modern ceiling or a custom shade to blend with colored walls. An optional black grille (reference GRILLHPRO525B) is also available for those who prefer a strong contrast.
Cutting-edge wireless connectivity
The FL502BT includes Bluetooth 5.1 with support for Qualcomm aptX, aptX HD, and aptX Adaptive codecs, placing these speakers among the most technologically advanced in their category. This multi-codec compatibility ensures high-quality audio transmission tailored to each listening situation.
The aptX HD codec allows 24-bit/48 kHz audio transmission at 576 kbps, delivering quality close to Hi-Res Audio over a wireless connection. Even more impressive, aptX Adaptive dynamically adjusts its bitrate between 279 and 420 kbps depending on transmission conditions and the content being played. This intelligent technology maintains optimal quality even in crowded radio-frequency environments, reducing dropouts and optimizing the power consumption of source devices.
The 335 mV auxiliary input completes the connectivity options, allowing wired connection of traditional sources such as CD players, TVs, or home automation systems. This dual wired/wireless approach guarantees near-universal compatibility with virtually all audio sources on the market.
Installation and setup: simplicity above all
The FL502BT installation process stands out for its remarkable accessibility. After cutting the 180 mm circular openings in the chosen surface, the installer simply positions the speakers, which are automatically held in place by the self-locking clamps. These clever mechanisms adapt to different wall thicknesses without requiring complex adjustments.
The connection between the active and passive speakers is made using a standard speaker cable, enabling a true stereo configuration. The active speaker only requires mains power, eliminating the need for an external amplifier and greatly simplifying cabling. This “all-in-one” approach reduces not only installation costs but also the technical clutter often associated with traditional multiroom audio systems.
Bluetooth pairing is intuitive, instantly turning any smartphone, tablet, or computer into a high-quality audio source. The range and stability of Bluetooth 5.1 ensure a reliable connection throughout the room, even through obstacles.
Practical applications and varied use cases
The FL502BT is at home in a wide variety of environments. In residential settings, it turns kitchens, bathrooms, and bedrooms into connected audio spaces without altering the interior architecture. Its compatibility with interactive whiteboards and projectors also makes it an ideal solution for meeting rooms and professional presentation areas.
Certification for humid environments further widens the scope of possibilities, allowing installation in bathrooms or covered semi-outdoor spaces. This versatility, combined with easy Bluetooth connection, makes the FL502BT particularly suitable for vacation rentals or reception areas where different users need to be able to play their music easily.
The optional acoustic kit KITRO4 allows further optimization of performance according to the specific acoustics of each installation, giving demanding users the possibility to fine-tune the sound reproduction to their particular environment.

Frequently Asked Questions
How do aptX codecs improve sound quality compared to standard Bluetooth?
The aptX codecs, particularly aptX HD and Adaptive integrated in the FL502BT, allow audio transmission at significantly higher bitrates than the standard SBC codec. aptX HD transmits 24-bit/48 kHz audio at 576 kbps versus 328 kbps for SBC, drastically reducing compression artifacts. aptX Adaptive goes even further by dynamically adjusting quality according to conditions, ensuring smooth listening even in dense Wi-Fi environments.
Can the FL502BT be installed in a bathroom?
The FL502BT speakers feature an ABS construction with a moisture-resistant metal grille. While they can handle the ambient humidity of a ventilated bathroom, it is recommended to position them away from direct water spray and to ensure adequate ventilation of the room to preserve their longevity.
What is the effective Bluetooth range, and can the speakers be controlled from an adjacent room?
With Bluetooth 5.1, the theoretical range can reach 30 meters in open space. In practice, through standard interior walls, you can expect a reliable range of 10 to 15 meters. Connection quality remains stable thanks to adaptive codecs that automatically adjust quality to maintain uninterrupted playback.
Does installation require any special electrical skills?
Basic installation requires only the ability to make clean circular cutouts and perform a simple electrical connection. The active speaker requires a standard mains power supply, and the connection to the passive speaker is made with a conventional speaker cable. The self-locking clamps eliminate the need for specialized tools for mounting.
How does the FL502BT’s sound quality compare to traditional hi-fi speakers?
With a design that delivers solid bass and clear detail at an accessible price, the FL502BT offers convincing acoustic performance for its class. The coaxial configuration provides better time coherence than many entry-level bookshelf speakers, while the optimized built-in amplification ensures perfect synergy between electronics and drivers.
Can multiple pairs of FL502BT be connected to create a multiroom system?
Each FL502BT pair operates independently with its own Bluetooth connection. For a truly synchronized multiroom system, you would need dedicated multiroom streaming solutions connected to the auxiliary inputs. Alternatively, some source devices support simultaneous streaming to multiple Bluetooth receivers, but perfect synchronization is not guaranteed.
