Cheap Polk Audio DB 400 4-Inch Coaxial Marine Speakers (Pair) (Electronics) Price

Built to withstand the toughest marine environments--including always-wet ski and wakeboarding boats--Polk Audio's DB 400 coaxial speakers offer topnotch performance and durability at a wallet-pleasing price. Each speaker is outfitted with a 4-inch polymer/mica composite cone woofer that's stiff yet lightweight, resulting in a big sound with little distortion. The 0.75-inch liquid-cooled silk/polymer composite dome tweeters, meanwhile, deliver clear, detailed highs that soar above the whines of your boat engine. Also along for the ride are low-mass, two-layer Kapton voice coils that produce a high sound output and robust power handling, along with durable Butyl rubber surrounds that won't fall apart under the stress of extreme temperatures.

Installation is abetted by the multi-hole mounting pattern and shallow mounting depth--a mere 1.81 inches. Meanwhile, listeners with few installation options will appreciate the flush and surface-mount swivel cups, which let you install the speakers in a variety of locations while still creating an optimal soundstage. The speakers even fit comfortably in cars, trucks, and other vehicles, though the marine certification makes them a particularly good choice for seafaring listeners.

Other features include a pole-plate heat sink that promotes better heat dissipation for superior power handling and reliability; a flat spider that enables faster and longer excursions; flexible woven leads sewn directly into the spider for greater dependability; an electronic tweeter protection circuit that protects your tweeters from accidental abuse; and reinforced, acoustically inert stamped steel baskets with an electrostatically powder-coated finish.

The DB 400s, which offer a frequency response of 85 Hz to 22 kHz and a peak power handling of 105 watts, measure 4 inches in diameter and are backed by a one-year warranty.
