Overview: The Polk Audio DXi Series 3-1/2" two-way speakers
(DXi350) are great in-dash or rear seat speakers. The DXi Series speakers utilize various Polk Audio
technologies for legendary Polk sound in your vehicle.
High Efficiency Design: The Polk Audio DXi Series speakers feature
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
Klipple 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 DXi350 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
Butyl Rubber Surrounds: For a
smoother response and improved durability, the speaker uses butyl rubber
Silk Soft-Dome Tweeters: Each Polk DXi350 speaker features
a 1/2" silk soft-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.
Bass Blockers: The DXi350 speakers include two 200
micro-farad capacitors which act as 200 Hz high-pass filters to block bass
frequencies from the speakers. These should be installed in-line on the positive
(+) speaker lead of each speaker.
Mounting: The Polk Audio DXi350 speakers fit in a standard 3-1/2
opening with two mounting holes. No grilles are supplied.
