One option is to purchase a soundbar. A soundbar is a flat bar that sits in front of or below your TV that houses multiple speakers and amplifiers. This will give you better quality sound without taking up too much space.Another option is to buy a floorstanding speaker. Floorstanding speakers are taller than soundbars and can be placed in the corner of the room to help reflect the sound throughout the space. If you have the space, it's also possible to set up surround sound by using multiple floorstanding speakers, a center channel speaker, and subwoofer.

There are a few things to consider when setting up a home theater in a small room. First, think about the layout of the room and how much space you have to work with.

Soundbars are slim and compact, and they can provide decent sound quality without taking up too much room. Another option is to go with a floor-standing speaker system. Floor-standing speakers can provide better sound quality than soundbars, but they take up more space.
