passive soundbars

Listings show a mix of inputs: several soundbars list HDMI, optical, AUX, and USB connections, while some speakers list only a single audio input in their basic specs.

Several listings specify a 20Hz–20kHz frequency response; at least one soundbar explicitly notes that its frequency response is not indicated.

Many listings call out wall-mounting or wall-mountable designs. Some speakers offer mounts that allow horizontal or vertical placement, and others note built-in keyholes for quick installation.

Several listings include a physical remote, and some soundbars also offer a companion app to control inputs and sound modes from a smartphone or tablet.

Some listings explicitly state no wireless support ("Wireless Technology: No Wireless Technology"), while others list Bluetooth or describe Bluetooth/wireless streaming in their descriptions.

Warranty periods include a 5 Year Limited Warranty on some center-channel speakers and a 1 Year Limited Warranty on several soundbars.
