11 Best Bookshelf Speakers (2024): Active, Passive, and Hi-Fi


Active (aka “powered”) audio system don’t require a separate amplifier or receiver. Instead, they’ve amplification (which is what makes the sound loud sufficient to play by way of audio system) inbuilt. These amps are sometimes custom-made for his or her particular drivers and cabinetry, which might ship efficiency advantages. Modern powered audio system additionally produce other perks, like totally wi-fi designs (other than energy cables) and wi-fi help to supply units by way of Wi-Fi or Bluetooth. They’ll usually present bodily connections for CD gamers, turntables, subwoofers, and TVs.

Passive audio system are wired audio system that require a separate amplifier or receiver and speaker cables for playback. This creates extra steps because you’ll want to seek out an amplifier with matching energy specs (extra on this under). The profit is that passive audio system are extra versatile and reliable, letting you combine and match them in a number of methods and configurations. When handled correctly, passive audio system can final for many years.

Impedance is a specification measured in ohms referring to a speaker’s resistance to electrical present move. Most passive audio system’ nominal impedance ranking (primarily the common impedance) is rated at 4, 6, or 8 ohms; the decrease the quantity the much less resistance to electrical present. You can consider it like plumbing pipes: the broader the pipe, the much less opposition to strain you get and the extra move, or electrical present, you’ll want. The upshot is that 4-ohm audio system are the toughest to drive, requiring probably the most energy. Much is made about impedance in audiophile circles, however most good amplifiers and receivers are rated for each 8-ohm and 4-ohm audio system, with acceptable wattage scores to match. For 6-ohm audio system, you’ll typically need an amplifier with a 6-ohm or 4-ohm impedance ranking and sufficient energy to match the speaker’s necessities (obtainable within the guide or web site).

Speaker energy necessities: Passive audio system embrace specs for his or her minimal and most energy necessities, measured in watts. Without getting too deep into the weeds about amplification varieties and energy effectivity, a superb rule of thumb is to select an amplifier with a wattage ranking per channel that carefully matches your speaker’s energy necessities for its nominal impedance ranking. If you’re having bother discovering the best match, you’ll typically need an amplifier that meets your speaker’s minimal energy necessities for its nominal impedance ranking.

Tethered connection choices: Most fashionable amplifiers and lively audio system supply a number of wired connections like analog enter (RCA or 3.5 mm), digital optical enter for CD gamers or TVs, and a subwoofer output for connecting a powered subwoofer. Many new methods connect with TVs over HDMI ARC too, letting you management fundamentals like energy and quantity along with your TV distant. They may supply a phono enter for turntables, although lots of our favourite turntables include a built-in phono preamp (or you should buy a separate phono preamp as wanted).

Wireless connection choices: Nearly all lively audio system—and lots of fashionable amplifiers—help Bluetooth. Wi-Fi connectivity can also be more and more customary to entry companies like Spotify Connect, Tidal Connect, AirPlay, and Google Cast. Wi-Fi is mostly most popular over Bluetooth for its improved sound high quality and conveniences like uninterrupted streaming and expanded wi-fi vary.
