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
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 DXi650s 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 DXi650s 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
