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.
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.
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 and the terminals and crossover components are not covered, we do not recommend using them in salt water environments.
