Really good stuff at a really great price is where it is at. So Polk Audio took really good stuff, grabbed it by the neck, held it down and force fed it Creatine and Ginko Biloba. Polk Audio mixed it up with patented Polk technologies and a reckless want for big volume output. Polk Audio produced speakers with better performance, bigger volume and better value the db Series. db Series is classic Polk Audio: outrageous performance and durability at a price that will your wallet.


Built to withstand the toughest marine environments including always wet ski and wakeboarding boats Polk Audio's DB 690 coaxial speakers offer topnotch performance and durability at a wallet pleasing price. Each oval speaker is equipped with a 6 by 9 inch, dynamic balanced, polymer/mica composite cone woofer/midrange that is inflexible still lightweight, ensuing in a big sound with little distortion. In the meantime, the 1 inch liquid cooled silk/polymer composite dome tweeters and agreeing 0.75 inch super tweeters deliver clear, in depth highs that soar above the whines of a ship 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, with lasting Butyl rubber surrounds that will not fall separately under the stress of extreme temperatures, long contact to sunlight, or the rigors of time.

Installation is abetted by the polarized, nickel plated terminals on the PCB terminal board, which ensure simple still secure wire connections. And although the marine certification makes the speakers a especially 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 correct midrange frequencies and glare free highs. The crossovers give the DB 690s more natural imaging than other speakers in this class, most of which use single stage, high pass only filters.

Other features are 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, adaptable 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 690s, which offer a frequency answer of 35 Hz to 22 kHz and a peak power handling of 300 watts, require a mounting cutout of 5.75 by 8.5 inches at a depth of up to 3.75 inches. they are also supported by a one year warranty.
