Pair of 6" x 9" DB690 Polk Audio car speakers. Since they are marine-certified, they can also be used on a boat as boat speakers. • polymer/mica composite woofer with butyl rubber surround • 1" silk/polymer composite midrange driver and 3/4" liquid-cooled, silk/polymer composite dome tweeter • certified for marine use • 2-way crossover network • recommended power range: 10-100 watts RMS • peak power handling: 300 watts • frequency response: 35-22,000 Hz • sensitivity: 93 dB The db690 6"x9" speaker combines a polymer/mica composite woofer with a rubber surround to keep the bass crisp and clean. You'll enjoy the smooth high-frequency output of the liquid-cooled, silk/polymer composite 3/4" dome tweeter. A 1" silk driver covers the crucial midrange area for uncolored reproduction of vocals and instruments. The db690 speakers handle plenty of power (up to 300 watts max / 100 watts RMS), yet they'll sound great powered by your aftermarket receiver. Instead of the high-pass filter found in most car speakers, a built-in 2-way crossover network sends the appropriate frequencies to each driver for cleaner sound and better imaging. Don't limit yourself to only using these speakers in your car — they've passed tough environmental testing that certifies them for marine use as well. Please, no scammers or lowballers.
