About the Polk Audio FXi3

Tom Mathew
If you demand high performance from your home theater system, you need surround speakers that provide great sound and exceptional flexibility. The FXi3 dipole/bipole speakers deliver subtle, detailed surround effects for stellar home theater. You'll enjoy a great mix of direct and indirect sound, thanks to the 45° angled driver arrays. Featuring the latest generation of Dynamic Balance® drivers, the FXi3 features a 1" silk/polymer dome tweeter and a 5-1/4" woofer mounted on one baffle, and a second matching tweeter on the other. Multichannel movies and music really shine!

If you demand high performance from your home theater system, you need surround speakers that provide great sound and exceptional flexibility. The FXi3 dipole/bipole speakers deliver subtle, detailed surround effects for stellar home theater. You'll enjoy a great mix of direct and indirect sound, thanks to the 45° angled driver arrays. Featuring the latest generation of Dynamic Balance® drivers, the FXi3 features a 1" silk/polymer dome tweeter and a 5-1/4" woofer mounted on one baffle, and a second matching tweeter on the other. Multichannel movies and music really shine!

A dipole/bipole switch changes the phase relationship between driver arrays for lots of placement flexibility. Depending on your setup, you can have the separate tweeter firing in phase with the other drivers (bipole), or out of phase (dipole). The bipole setting is great for speakers placed behind your listening position, and provides clear, directional sound, while dipole usage is ideal for placement to the side of your listening position and results in a more diffuse soundfield. Also includes a keyhole slot for wall-mounting. Voice-matched to Polk's RTi tower and bookshelf speakers and CSi center channel speakers.

Features

Enclosure Design: Each enclosure has a triangular shape with the speaker faces angled at 45 degrees. One face has a tweeter and a woofer, while the other face has a tweeter and port tube opening. The switch for selecting Dipole or Bipole operation is located in the terminal cup on each speaker. One of the speakers is specifically designed for the "left" channel and the other for the "right" channel.

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 a polymer composite woofer for smooth wide-range response with low distortion. For high performance durability, each woofer uses a butyl rubber surround.

Silk/Polymer Tweeters: Each speaker has dual 1" silk/polymer dome tweeters that provide clear, detailed highs and spacious surround effects. Each tweeter uses a heat sink on the Neodymium magnet for superior heat dissipation, power handling and reliability.

Port: On the side with only a tweeter, there is a single port tube opening for increased and extended bass response.

Acoustically Inert Cabinets: Each speaker cabinet features all-MDF construction with internal bracings that virtually eliminate sound-muddying resonance.

Anti-Diffraction Grilles: The floating anti-diffraction grilles minimize grille diffraction for spacious, 3-dimensional imaging.

5-Way Binding Posts: The gold-plated 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.

Dipole/Bipole Switch: There is a switch, located in the terminal cup, that allows each speaker to be used as a Dipole (out of phase) or Bipole (in phase) speaker. If you're mounting the speakers on the side walls in line with your listening position, the dipole mode will create a diffuse, ambient soundfield. If you're placing them behind your position, the bipole mode fires the drivers in phase to flood your room with surround sound. When used with a Dolby Digital system, the surround speaker setting should be set to small.

Wall Mounting: The bracket on the back of each speaker has two keyhole slots, allowing the speaker to be mounted on the wall using optional hardware.

Note

Frequency Response Note: The overall frequency response is 50Hz-27kHz and the -3dB frequency response is 60-26kHz.
