A great pair of bookshelf speakers should last for years and deliver better performance than you can get from all-in-one Bluetooth and Wi-Fi tabletop speakers. These speakers are sized to fit on a shelf or to be mounted on a stand. They take up less space than tower speakers, but they put out less bass. (If you want more bass, you can often add a subwoofer.)This guide covers two categories: passive bookshelf speakers, which you need to pair with a stereo amplifier or an AV receiver, and powered bookshelf speakers, which have built-in amplification and inputs for directly connecting your sources.
