Floor speakers are the most important aspect of any home theater system; realistically, they're the only speakers you could use on their own and still wind up with respectable sound. Some folks might try to get away with just a center channel like a sound bar, but it's really not the same. Some tower speakers can create enormous sound fields that approach that of full surround sound, which a lone center channel or sound bar could never accomplish. Best floor speakers in 2022 come in all shapes and sizes, and are designed for a variety of listening styles and intended uses; rather than looking solely at ranking or price, remember to consider how and where you will use these speakers when reading reviews. I'm sure the Focal Grande Utopia EM or Sound Lab U-1PX would sound great no matter where you put them, but they are designed for large dedicated listening spaces; smaller speakers like the Triton Two would probably sound (and look) much more appropriate in a master bedroom or smaller den.
There are two main types of floor speakers: dynamic and electrostatic. Dynamic speakers are your traditional air-moving cones with a diaphragm, they account for virtually all "normal" speakers. Electrostatic speakers utilize a charged field within which a very thin membrane vibrates to create sound waves; the resulting sound is very fast and can produce an extremely large soundstage with peerless imaging, but they have a smaller sweet spot, meaning that you should point the speakers directly at your intended listening position; the sound won't be as realistic or spacious from outside the sweet spot, which is usually big enough for 1-3 people. Dynamic speakers have a sweet spot, too, but it is usually much larger, and they sound better outside the sweet spot than electrostatics. Electrostats are usually bought by audiophiles who use their speakers mostly for music, but with a supporting subwoofer they can sound great with movies, too. If you've never owned electrostats, please try to demo before buying, as they sound noticeably different from dynamic speakers and are considered to be an acquired taste by many.
The speakers that comprise the following lists range from excellent budget models, which deliver great bang for your buck, all the way up to peak HiFi setups and the kinds of speakers used for mastering in the world’s most renowned studios. I advise most first-time buyers to start low; many non-audiophiles won't feel the need to spend more than a few hundred dollars to get very satisfying budget models, and I would bet that most people will be happy with speakers like the Pioneer FS-52 without feeling the need to upgrade. That said, you get what you pay for, and if you’re ready to shell out a thousand or more, you'll get serious audio that will make your local movie theater sound muddy and undetailed, and if you decide to roll with the big dogs and spend over $5,000, you're getting into the realm of professional-class sound and will probably never want to go back.
In the end, every speaker listed here is great for its intended purpose, and no matter what your budget, there are speakers out there for everyone. Have a good read, and prepare for a big package to show up on your doorstep soon!
