Choosing speakers for your needs

A high-fidelity stereo system requires two front speakers, generally floorstanding or bookshelf models depending on the size of the room. For home theater, the setup expands with center speakers dedicated to dialogue, side or rear surround speakers, and a subwoofer to reinforce the bass. Formats such as 5.1, 7.1 or Dolby Atmos incorporate several specialized speakers to create an immersive soundstage.

The different types of speakers

Floorstanding speakers offer an extended frequency response and a large enclosure volume for bass. Their height allows optimal placement of the drivers at ear level. More compact bookshelf speakers sit on furniture or a dedicated stand and are suitable for rooms of 15 to 30 m². Their smaller size limits cabinet coloration while ensuring accurate reproduction.

Soundbars offer a compact alternative for improving the sound of a television without adding multiple speakers. In-wall speakers or in-ceiling speakers blend discreetly into the interior architecture and are particularly useful for surround or Atmos channels. Outdoor speakers withstand the elements to provide sound on patios and in gardens.

Passive and active speakers

Passive speakers, the most common type in hi-fi, require an external amplifier. They incorporate drivers and a passive crossover to distribute the frequencies. Connected speakers or studio monitors feature built-in amplification, often with USB or optical digital inputs, or wireless Bluetooth and Wi-Fi connectivity. These active speakers simplify setup by connecting directly to audio sources.

Technical criteria

Sensitivity or efficiency, expressed in dB, indicates how effectively a speaker converts electrical power into sound pressure. Floorstanding speakers generally reach 40 to 60 Hz in the bass range, while bookshelf speakers rarely extend below 50-60 Hz. A subwoofer then complements the system for the lowest frequencies.

The number of ways defines how the drivers are divided: 2-way (tweeter + mid/bass), 3-way (tweeter + midrange + bass) or more. The enclosure can be sealed or bass-reflex with a port to optimize bass reproduction. The impedance, generally 4, 6 or 8 ohms, must match the amplifier’s capabilities.

Building your system

For stereo listening, two floorstanding or bookshelf speakers are sufficient. Rooms up to 20 m² can accommodate compact speakers, while spaces of 20 to 40 m² require floorstanding models. For home theater, 5.1 speaker packages or 5.1.2 packages ensure consistent sound across all channels. The front and center speakers reproduce most of the audio content, the surround speakers create the atmosphere, and Atmos speakers add the vertical dimension.

French brands such as Focal, Triangle, Cabasse or Elipson sit alongside international benchmarks B&W, KEF, Klipsch, Dali, Monitor Audio or Yamaha. Each manufacturer develops its own sound signature, some favoring neutrality for monitoring, others high efficiency, or the smoothness of British sound.

Connectivity and new uses

Connected speakers incorporate Bluetooth, Wi-Fi, Chromecast or AirPlay 2 protocols to stream music from a smartphone, tablet or streaming services. Multiroom audio allows several speakers in different rooms to be synchronized. Some models have an HDMI ARC input to receive sound directly from the television.

Portable Bluetooth speakers offer a mobile solution for listening to music on the go, with battery-powered operation. Studio monitors, used in studios, provide analytical and accurate reproduction for audio mixing, also useful for producers and musicians in home studios.

Installation and placement

Speaker positioning has a major influence on listening quality. In a stereo setup, they form an equilateral triangle with the listening position. The distance from the walls affects low-frequency response. Bookshelf speakers are ideally placed on stands at ear level or on wall mounts. Speaker cables, banana plugs and accessories optimize connections to the amplifier.
