POLK AUDIO FXi A4 Dipole/Bipole Surround Speakers Black Pair

The F/XiA4's engine is the dual Dynamic Balance 1" dome tweeter design and a 5 1/4" Dynamic Balance driver that produces believable real-life effects at prodigious volumes. The selectable bipole/dipole function allows you to configure it to your space and 7.1 systems, and the smaller cabinet enables it to fit in more places.

Features

• The trapezoidal shaped cabinets aim the drivers and tweeters in opposing directions to produce a more realistically diffused wavefront and wide, lifelike imaging of surround sound.
• With the flip of a switch, Polk's dipole/bipole circuitry changes the sound-field from direct to indirect radiation patterns enabling you to place the surround speaker beside or behind you, depending on your listening room setup.
• Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.
• Polk's proprietary, patented Dynamic Balance technology allows their engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
• Durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a life-time of reliable sound.
• The F/XiA Cascade Tapered Crossover eliminates the comb filtering and beaming, common to multi-driver speakers, which degrades the quality of the audio and collapses the sound-stage.
• Patented Acoustic Resonance Control (ARC) technology suppresses cabinet resonance that causes distortion to ensure clear and natural sound.
• Computer-modeled anti-diffraction grilles enhance the good looks while minimizing sonic interference.
• All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.
• Gold-plated, professional-style 5-way binding posts offer the most secure connection options.
