Get big, room-filling sound at an affordable price! The high-performance Monitor 50s feature Polk's famous Dynamic Balance® drivers — a 1" dome tweeter and dual 5-1/4" woofers dish out rich, vibrant sound all across the audio spectrum. Enjoy pristine reproduction of stereo music, or make these impressive tower speakers an integral part of a voice-matched Monitor home theater setup, either as front or a surround speakers.

The Monitor 50s are constructed with non-resonant MDF, and include front-to-back and side-to-side internal bracings for cleaner, clearer, more lifelike sound. Bold, fat stabilizer feet keep these tall, slender tower speakers steady on carpet or hardwood floors. And dual 5-way binding posts allow for bi-wiring or bi-amping.

Floor-standing speakers — still standing tall

Sure, floor-standing tower speakers buck the industry trend toward smaller, visually inconspicuous speakers, but they're hard to beat if great sound is your primary goal. Tower speakers produce powerful sound with excellent bass, making them a great choice for serious music lovers and for folks who want high-impact home theater.

Crutchfield Customer Review (What's this?)

If you can still find this model, compare it to the Polk TSI-300, they are almost identical in sound. Very good music/voice/movie/game reproduction without spending over $1500 on a full system. Smooth tweeter makes a soft warm sound, perfect for relaxing music, while retaining the ability to produce a movie and game with ease. I have mine bi-amped with Onkyo TX-SR606 and am very pleased.

Product Research



Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Polymer Composite Woofers: Each speaker features two lightweight, yet stiff Bi-Laminate composite woofers with good damping, giving you high efficiency, excellent bass, and low distortion. For high performance durability, each woofer uses a butyl rubber surround.

Silk/Polymer Tweeters: Each speaker has a 1" fabric/polymer dome tweeter that provides clear, detailed highs. Each tweeter uses a heat sink on the Neodymium magnet for superior heat dissipation, power handling and reliability.

Acoustically Inert Cabinets: The speaker cabinets feature all-MDF construction with internal bracings that virtually eliminate sound-muddying resonance.

Ports: There is a single critically-tuned port opening on the front of each speaker that has low port noise for increased and extended bass response.

Stabilizer Feet: The large stabilizer feet ensure stability on carpet and hard floors for precise bass response and superior imaging.

Dual 5-Way Binding Posts: Each speaker has two sets of gold-plated 5-way binding posts connected by gold-plated jumpers. Using the dual 5-way binding posts, you can bi-amp or bi-wire the speakers.

Magnetically Shielded: Each speaker is magnetically shielded, allowing you to place them near your television without distorting the picture.


Frequency Response Note: The overall frequency response is 42 Hz-25 kHz and the -3 dB frequency response is 57 Hz-24 kHz.
