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.
Rubber Surrounds: The inner and outer woofer surrounds are Santoprene rubber, to keep water from leaking through the speaker.
Swivel Tweeters: The 1" tweeters pivot, so they can be angled for optimum imaging. The tweeter material is Terylene, a brand name of polyethylene terephthalate (PET).
Neodymium Magnets: The speakers' neodymium magnets offer exceptional strength to performance ratio and are small and lightweight.
Basket: The speaker baskets are fiberglass reinforced ABS, lightweight and corrosion resistant.
Crossover: The crossover components are coated with epoxy to prevent corrosion. The low pass filter is 1st order (6 dB/octave) and the high pass filter is 2nd order (12 dB/octave).
Ultra-Marine Certified: Polk MM1 Series speakers are tested to withstand exposure to salt-fog, UV rays, and humidity, so they'll work well in boats and cars. They also include stainless mounting hardware for corrosion resistance.
Drainage: The speaker should be mounted so the slots along the perimeter of one side of the basket are at the bottom, so any water trapped between the speaker and grille can drain.
Size Classification Note: These speakers are marketed as 6-1/2"; they will fit in standard 6-1/2" speaker openings, but do not use the standard 6-1/2" speaker bolt pattern. In order to install them in standard 6-1/2" speaker openings you must drill new screw holes. If new holes are drilled in the mounting surface of the car, no bracket is needed. If drilling in the car is not an option, the included brackets can be used, which have standard 6-1/2" mounting holes, the Ford non-symmetric four hole pattern, and non-standard 6-3/4" three and four hole patterns.
