Polk Audio MM 572

Features

Mounting Applications: Polk Audio describes these speakers as 5x7, but they also fit many 6x8 applications. Please enter your vehicle information to confirm fit.

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 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 trapped water can drain.

Terminals: These speakers have 0.25" positive (+) terminals and 0.187" negative (-) terminals, which are too large for the speaker harnesses supplied by Crutchfield for many vehicle-specific applications. The speaker wire included by Polk Audio has the correct size terminals attached, so that can be spliced to an adapter harness, or optional crimp-on female quick slides can be purchased (item number 120FQS10PK, sold separately).
