Sound Quality: What Do They Really Sound Like?
Polk has a long-standing reputation for producing speakers that deliver solid audio performance without needing to shatter your budget. The Monitor XT20 largely lives up to this legacy, with most users agreeing the sound experience is quite satisfying for both music and home theater.
Crisp Highs and Detailed Mids: Thanks to the 1” Terylene tweeter, high-frequency sounds like cymbals, vocal sibilance, and subtle sound effects come through clear and refined. This makes dialogue in movies strikingly natural, and music genres that rely on treble detail—like classical and jazz—particularly enjoyable. Customers describe the highs as smooth and non-fatiguing, with no glaring sharpness that can sometimes hurt the ears after extended listening.
Tight and Punchy Bass: With the 6.5” polypropylene woofer, bass response is above average for bookshelf speakers of this size. Listeners often note a controlled and “punchy” low end, capable of handling action movie soundtracks and basslines in modern music with authority. While you might not get the deep rumble of a dedicated subwoofer, the XT20 shines in delivering balanced bass that fills the room without muddiness.
Wide Soundstage and Room-Filling Volume: The Dynamically Balanced design not only cuts distortion but helps create a wide, immersive soundstage. Most users are impressed by how well these speakers can fill medium-sized rooms, with a sense of space that allows for sound layering, especially important for Dolby Atmos and DTS:X content. Even at higher volumes, the speakers maintain clarity without distortion or harshness.
Potential Drawbacks: Some audiophiles mention that while the Monitor XT20 performs admirably for its price point and size, it might lack the last ounce of finesse and ultra-deep bass you’d expect from premium or floor-standing speakers. Also, while the compact design is a boon for placement flexibility, true sound purists might prefer larger woofers for certain heavy bass genres. Lastly, as these are bookshelves or surround speakers, pairing with a quality subwoofer (like the Polk MXT12) is recommended for a full-frequency, home theater experience.

FAQ
Q. Do I need an amplifier or AVR?
A. Yes. The XT20s are passive speakers and require an integrated amp or AV receiver. Aim for 30–200 W per channel into 8 ohms.
Q. Are these “Atmos speakers” by themselves?
A. No. They’re conventional bookshelves that work in Atmos/DTS:X systems when used with a compatible AVR. For height effects, add dedicated height modules (e.g., Polk MXT90) or in-ceiling speakers.
Q. Do I need a subwoofer?
A. Not strictly—but for movies and bass-heavy music, a subwoofer extends low-end impact and delivers true theater rumble.
Q. Can I wall-mount them?
A. They don’t include built-in keyholes/rails. Most people use shelves or stands; third-party brackets/shelves can be used if you want them on a wall.
Q. Will banana plugs work?
A. Yes—standard 5-way binding posts accept banana plugs, spades, or bare wire.
Q. How far from the wall should I place them?
A. Start with 6–12 inches between the rear port and the wall. Adjust by ear for the tightest bass and best imaging.
Q. What wire gauge should I use?
A. 16-gauge is fine for short runs; 14-gauge for longer distances or if your AVR is farther away.
Q. How big of a room can they fill?
A. They’re ideal as mains in small-to-medium rooms and make excellent surrounds in larger theaters.
