Choose an amplifier or receiver that matches each passive speaker’s rated impedance and power-handling requirements, and provide the appropriate number of channels for the installation. Three-channel soundbars typically pair with an A/V receiver or multichannel amplifier, while passive subwoofers require a compatible subwoofer amplifier and outdoor speakers may call for an amplifier suited to the intended system.

Choose bookshelf speakers for flexible, visible placement; in-wall speakers for a discreet installation; outdoor speakers for patios and backyards; and soundbar-style speakers for a streamlined front stage beneath or near a TV. Consider the room, mounting options, listening goals, and available amplification, since passive speakers require an external amplifier or receiver.

For sound quality, review the driver configuration, woofer and tweeter materials, cabinet design, passive radiators, and channel layout, such as separate left, center, and right channels in a soundbar. For system matching and room coverage, confirm the speaker’s amplifier requirements, impedance, power handling, size, mounting style, and intended environment, such as in-wall, TV-front, indoor, or outdoor installations.

Passive speakers integrate with home theater systems by connecting to an audio-video receiver or separate amplifier, with three-channel soundbars providing left, center, and right front-stage audio and in-wall subwoofers adding bass. For distributed audio and multi-room systems, installers can connect speaker zones to compatible amplifiers, including outdoor speakers powered by a multi-room amplifier, to extend audio across living areas, patios, and other spaces.
