The db691 is also the first speaker in the db series to offer two tweeters instead of one. One tweeter is a 1” liquid-cooled silk/polymer composite dome tweeter, whereas the other is described as a 1” super tweeter. In addition, the Audio db691 features a pole plate heat sink for improved heat dissipation, muscular ABS Grilles based on MOMO designs, flat Spiders for longer excursion linear motion, and a rock solid stamped steel basket for easier installation. Equipped to offer “superior” sound quality, the Polk Audio db691 is cited as being the finest 6” x 9” loudspeaker available in the car-audio market.
