Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Features
High Efficiency Design: The Polk Audio DXi Series speakers
feature a high efficiency design so less amplifier power is needed for more
audio output, meaning better sound and more volume using less power.
Dynamic Balance Driver Technology: 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.
Klippel Optimized Components: For a driver to reproduce
complex sounds accurately, the cone must move in exactly the same distance and
manner in both directions of travel. The Klippel distortion analyzer, a device
that uses a laser and sophisticated software to do large-scale analysis of
drivers in motion, lets Polk optimize the speaker's motor structure, voice coil
alignment, and suspension to yield the best possible performance.
Composite Cones: Each Polk DXi500 speaker features a Dynamic
Balance, polymer/mica composite cone woofer. These composite cones feature
tremendous stiffness-to mass ratio. Lower mass means faster transients and finer
detail.
Butyl Rubber Surrounds: For a smoother response and improved
durability, the speaker uses butyl rubber surrounds.
Silk Dome Tweeters: Each Polk DXi500 speaker features a 3/4"
silk dome tweeter for clearer, more accurate highs. Each tweeter employs a
light-weight neodymium magnet for higher efficiency.
2-way Crossover Network: The built-in 2-way crossover
network sends the appropriate frequencies to each driver for cleaner sound and
better imaging.
Mounting: The Polk Audio DXi500 speakers fit in a standard
5" application (approximately 4" opening) with four mounting holes.
