Polk Audio DB 525 5.25-Inch Coaxial Vehicle Speakers (Pair, Black) Specifications
Built to withstand the toughest marine environments--including always-wet ski and wakeboarding boats--Polk Audio's DB 525 coaxial speakers offer topnotch performance and durability at a wallet-pleasing price. Each round speaker is outfitted with a 5.25-inch, dynamic-balanced, polymer/mica composite cone woofer/midrange that's stiff yet lightweight, resulting in a big sound with little distortion. The 0.75-inch liquid-cooled silk/polymer composite dome tweeters with neodymium magnets, meanwhile, deliver clear, detailed highs that soar above the whines of a boat or car 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, long exposure to sunlight, or the rigors of time.
Installation is abetted by the polarized, nickel-plated terminals on the PCB terminal board, which ensure simple yet secure wire connections. And though the marine certification makes the speakers a particularly good choice for seafaring listeners, the speakers also fit comfortably in cars, trucks, and other vehicles.
Listeners with finely tuned ears will dig the speakers' high- and low-pass crossovers, which deliver clearer, more accurate midrange frequencies and glare-free highs. The crossovers give the DB 525s more natural imaging than other speakers in this class, most of which use single-stage, high-pass-only filters.
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; rock-solid, acoustically inert stamped steel baskets with a rustproof gunmetal gray finish; and muscular, computer-optimized ABS grilles.
The DB 525s, which offer a frequency response of 60 Hz to 22 kHz and a peak power handling of 135 watts, require a mounting cutout of 4.65 inches in diameter at a depth of up to 2.62 inches. They're also backed by a one-year warranty.
