High Efficiency Design: The Polk Audio DXi Series speakers
feature a high efficiency design; meaning better sound and more volume using
Dynamic Balance Driver Technology: Dynamic Balance is a
proprietary Polk Audio technology using laser imaging to determine what
combination of speaker materials creates the least 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 exactly the same distance and
manner in both directions. 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 woofer features a Dynamic Balance,
Bi-Laminate composite, polypropylene cone woofer. These composite cones feature
tremendous stiffness-to mass ratio, resulting in faster transients and finer
Rubber Surrounds: For a smoother response and improved
durability, the speaker uses rubber surrounds.
Mounting: Out of the box the DXi 6501 woofers are a direct
replacement for many standard 6-3/4" applications. Mounting brackets
are included with holes matching standard 6-1/2" (3-hole), Ford 6-1/2"
(asymmetrical 4-hole), and various 6-3/4" applications. Without using the
mounting brackets the speaker also fits into many standard 6-1/2" openings,
but the four hole pattern is not a direct replacement (new screw holes would
need to be drilled; in this instance mounting depth would be 1.947" and
mounting height 0.427"; this application does not sort in the Crutchfield
Vehicle Selector because using the mounting bracket requires no modification,
and is therefore the preferred 6-1/2" mounting method).
Silk Dome Tweeters: The 1" liquid-cooled, silk/polymer
composite dome tweeters provide clear, detailed highs.
Neodymium Magnets: Each tweeter employs a light-weight
neodymium magnet for better efficiency.
Mounting: The supplied mounting cups allow you to surface or
flush mount the tweeters. The tweeters swivel in the flush-mount housings,
allowing you to adjust them for optimum imaging.
Tweeter Mounting Dimensions:
||0.21" (screw depth)
Design: The outboard 2-way Butterworth crossovers have a 12
dB/octave slope (high-pass and low-pass).
Tweeter Level Switch: You can adjust the output of the
tweeter to match a level appropriate to your vehicle or your system. On the end
of crossover (opposite the terminals) the switch can be set to -3 dB, 0 dB, or
Protection Circuit: Each crossover has a built-in electronic
circuit that protects the tweeter from accidental overdriving.
Connections: The crossover inputs and outputs are screw
terminals. The terminals will accommodate the included wire or spade connectors
up to 0.3" wide.
Mounting: There are two mounting holes in the base of each
crossover; the cover must be removed to install the mounting screws.
