Dynamic Balance: 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.
Woofer Mounting: The woofer baskets have multiple mounting
holes and are designed to fit standard 3-hole 6-1/2, Ford's 4-hole 6-1/2, and
6-3/4 applications. (A speaker baffle should be used to seal the inner ring of
screw holes in 6-3/4 installations.) The included adapter brackets can be used
to fit many specialized factory speaker applications. The brackets are also
useful as a spacer in shallow locations; the brackets add 0.232" to the woofers'
mounting height and subtract 0.232" from the mounting depth. Please enter your
vehicle information to confirm fit.
Tweeter Mounting: The supplied mounting cups allow you to
surface or flush mount the tweeters. The tweeters swivel slightly in the flush
mount housings, allowing you to adjust them for optimum imaging.
Tweeter Mounting Dimensions:
| ||Flush Mount ||Surface Mount |
Height ||0.314" ||0.884" |
|Mounting Depth ||0.731" ||screw depth |
|Cutout Diameter ||1.780" ||N/A |
|Frame Diameter ||2.135" ||1.75" |
Crossover: The outboard crossovers have screw terminal inputs
and outputs (0.3" wide). A jumper inside each crossover allows you to adjust
the tweeter output level; choose 0 dB, +3 dB, or +6 dB. There are two screw holes
in the base of each crossover for mounting.
- Width: 2.6"
- Height: 1.2"
- Depth: 4.73"
Marine Certification: Polk speakers are marine certified,
making them a good choice for boats in fresh water, convertibles, motorcycles,
ATVs, and other applications where the speaker might get wet. Because they have
coated steel baskets, the terminals are not covered, and the crossovers are not
sealed, we do not recommend using them in salt water environments.
