Polk Audio DB692 DB+ Series Coaxial Marine 6x9 Speaker for Car & Boat, 3 Way Car Audio, 30-22kHz Frequency Response, Polypropylene Woofer Cone & 1/2" Silk Dome Tweeter, Easy Installation

Awesome sound quality. Crisp mids and highs with the right amount of bass. If you plan on floating or submerging the speaker you will need to silicone inside the speaker magnet under the sticker.

My oval JBL Marine speakers finally started crackling after 17 years of use, so it was time to replace them. I searched high and low and settled on these speakers. Aside from the fact that they fit almost perfectly in the existing holes (I say "almost" because they are a tad smaller than the JBL speakers), the sound was fantastic; I was able to crank the volume with no distortion and solid bass/treble. The price was definitely competitive too; not the lowest, but certainly not the highest. I would definitely recommend these for any boat.

I've been using the Polk Audio DB692 DB+ speakers in a custom Bluetooth portable build inside an Apache 2800 weatherproof case, and man, these things deliver big time. They're easily the best-sounding 6x9s I've ever messed with in any setup. The clarity is outstanding, with those crisp highs from the silk dome tweeter and super tweeter never getting piercing, mids that keep vocals and instruments sounding natural and forward, and surprisingly punchy bass for a single coaxial driver in a sealed-ish enclosure like this. If you're putting together a DIY portable speaker and want something that punches above its price without needing subs or fancy tweaks, grab these. You won't regret it.

Sound great, some of my favorite speakers to work with.

Bought these as replacement speakers for my harley-davidson. Just put them in this weekend. Haven't had a chance to test them. But Polk makes good stuff so I don't expect any issues

Sounds good, but a little pricey when not on sale.

Great speakers, I installed them in a boat they sound great

works great
