Review: Atmos speakers at down to earth prices. - Perfect solution for Atmos speakers up on my front wall.
Review: Highly recommended for anyone looking to get more out of their Atmos setup. - I'll admit, I questioned whether adding height speakers would really make that much of a difference. After installing the Polk Monitor XT90s on top of my XT70 tower speakers, I quickly realized why so many home theater enthusiasts recommend them. The biggest improvement wasn't that sounds were louder—it was that movies felt more immersive. Rain, aircraft, and ambient effects have a sense of height that wasn't there before. Instead of all the sound coming from around the TV, it feels like it fills the room. Installation was incredibly simple since they're designed to sit directly on top of the compatible Polk XT towers. They look like they belong there, making the setup clean and seamless without needing to mount speakers on the ceiling. Like the rest of the Monitor XT series, the sound is clear and well-balanced. They blend naturally with the rest of my system instead of calling attention to themselves, which is exactly what you want from height speakers. If you're already building a Dolby Atmos setup with Polk Monitor XT speakers, I wouldn't hesitate to recommend these. They're one of those upgrades you don't fully appreciate until you hear the difference for yourself. For my home theater, they completed the experience, and I'm really glad I decided to add them.
