Elac Debut ConneX DCB41 black (pack of 2)

The powered speakers Elac Debut ConneX DCB41 are compact speakers measuring 140 x 247 x 170 mm, equipped with a 2 x 50 W Class D amplifier. They offer multiple connectivity options including HDMI ARC, USB 96/24, a phono input with built-in preamplifier, optical, and Bluetooth aptX. Designed with contributions from Oleg Bogdanov, they aim to deliver coherent sound reproduction despite their small form factor.

A concentrate of technology

The construction of the Debut ConneX DCB41 reveals careful attention to acoustic detail. The reinforced 12 mm MDF cabinet provides a solid foundation that limits unwanted resonances. Each speaker features a 19 mm soft-dome tweeter housed in a custom waveguide, paired with a 114 mm polypropylene woofer with a long-throw suspension. This two-way configuration, with the crossover set at 2 kHz, ensures a smooth transition between frequency ranges.

The rear bass-reflex port uses a distinctive “S” configuration. This particular geometry minimizes airflow noise while optimizing low-frequency extension. The removable grilles, attached via pegs, let you tailor the look to your preference, though the mounting system is conventional compared with today’s magnetic solutions.

One speaker houses all the electronics, including Class D amplification developed specifically for these drivers. This “primary–secondary” approach simplifies setup: a simple 1.7 m supplied speaker cable links the two speakers. A switch lets you swap channels depending on the position of the amplified speaker, making it easier to place near your sources.

The infrared remote controls volume, source selection, and the XBass function. The latter offers two levels of bass boost: +3.5 dB at 55 Hz for level 1, and +7 dB for level 2. Unlike many bass enhancers, XBass maintains a measured action that enriches without distorting.

Connectivity designed for modern use

The wealth of connections sets the DCB41 apart from direct competitors. The HDMI ARC interface is probably the main asset: it enables seamless integration with a TV, with volume controllable via the TV remote thanks to CEC. This feature, usually reserved for pricier models, positions the Elac as a credible alternative to soundbars.

The USB Type-B input accepts signals up to 96 kHz/24-bit from a Windows or Mac computer without requiring a dedicated driver. Volume can then be controlled directly from the computer. The optical input offers the same resolution capabilities, ideal for connecting a game console or a network player.

The built-in phono preamplifier is another welcome highlight. A simple switch toggles the RCA input between line and MM phono, with a ground screw included for turntables. This versatility avoids the need for an external preamp, greatly simplifying turntable setup.

Bluetooth connectivity with the aptX codec ensures CD-quality wireless transmission from compatible devices. A subwoofer output lets you expand the system with an active subwoofer, compensating for the physical limitations inherent to small speaker volumes.

Acoustic performance and day-to-day use

The DCB41 show a surprising ability to handle their physical limitations intelligently. The soundstage extends slightly beyond the plane of the speakers, creating a coherent sense of space. Stereo imaging benefits from the tweeter’s waveguide, providing controlled dispersion that eases placement. The speakers tolerate relatively close proximity to rear walls thanks to the S-shaped port that minimizes turbulence.

The stated frequency response of 66 Hz to 25 kHz in an anechoic chamber (50 Hz to 25 kHz in-room) reflects respectable bass extension for drivers of this size. The maximum sound pressure level of 102 dB at 1 meter allows comfortable listening in medium-sized rooms, though large spaces or party-level volumes remain out of reach.

The volume knob located on the back of the amplified speaker may seem inconvenient, but using the remote or controlling volume via the source (TV, computer) more than compensates. The lack of visual volume indication calls for caution when switching sources to avoid unpleasant surprises.

The front LED indicates the selected source with different colors: green for HDMI, white for analog, etc. This discreet indicator can be disabled via the remote for home cinema setups. USB-upgradeable firmware ensures future compatibility with new audio standards.
