Best 6X9 Marine Speakers Reviews

There are a ton of things to think about when you own a boat and obviously speakers aren’t necessarily at the top of the list. However, upgrading your boat speakers should be on your list somewhere, because unless you have a high-end boat shipped with premium marine stereo system, chances are high that your boat speakers aren’t anything to write home about.

Great sounding speakers are a key element in any high-performance marine audio system. They will make a night and day difference and will really add to your boating enjoyment.

That said, It should be noted that upgrading your stock speakers to aftermarket ones is one of the most cost-effective ways to boot your sound quality. That said, let’s take a closer look at some of the best 6X9 marine speakers that you can buy.

No question about our number one here. Polk Audio DB692 speakers are some of the best 6X9 marine speakers in the market. They’re very well-engineered, very efficient and strong enough to handle harsh outdoor conditions such as salt, water and UV light.

These 3-way marine speakers are featured with 6″x9″ polypropylene woofer cones supported with strong durable rubber surround for solid playback and long lasting performance. These cones are made to deliver high-impact yet natural bass.

To complement their strong bass output, these speakers use 3/4″ silk dome tweeters and 1/2″ super-tweeters to deliver bright highs without shrillness to give you a vibrant, live soundstage, while the built-in crossover keeps the highs and lows flowing to the proper drivers.

The tweeters on these speakers feature zero protrusion design which will allow you to use your factory speaker grille with ease for a flush, seamless look.

Polk Audio DB692 are marine certified speakers with IP55 rating (water- and dirt-resistant) and tested for salt-fog, UV and humidity.

Additionally, the non-corrosive plastic grille, the polypropylene UV tolerant cone, the waterproof inner and outer surrounds, and stainless steel mounting hardware that these speakers are featured with allow them to be fully protected against outdoor elements.

Furthermore, these speakers feature a low mounting profile, which means that you can mount them in nearly any enclosure. And despite these speakers being marine certified, you can also mount them in your car, boat, ATV’s — you name it. This is why the Polk DB+ is one of the best marine speakers on the market.

Polk Audio DB692 boat speakers are rated for 93dB sensitivity rating and can handle a ton of power — 150 watts of power on continuous basis. These speakers will do fine running off your aftermarket receiver, but they’ll truly come into their own when driven by an outboard amp.

Within the audio space, JBL is one of the oldest and trusted names.. They’ve been business for a very long time and have been been churning out quality speakers of different types.

The MS9520 are the best 6X9 marine marine speakers in the JBL MS series. These speakers are designed for use in harsh marine environment. They’re built with high grade materials that can handle nature elements such as sun, spray and moisture. They’re featured with waterproof motor structures, a one-piece cast-polymer basket, a sealed magnet, and durable rubber surrounds.

JBL is recognized for their top-notch speakers that deliver quality sound, so it’s no surprise that they put some of their best thinking into these 6X9 boat speakers.

JBL MS9520 speakers are very well-engineered. They’re featured with oversized Plus One™ polypropylene cones which offer higher sensitivity, increased low-frequency thump, and a richer overall listening experience.

As for highs, JBL equipped these boat speakers with grille-mounted balanced-dome tweeters for smooth, crystal clear high frequency response that that will cut through the wind, the water, and the engine noise.

These JBL 6X9 marine speakers are rated for 92dB sensitivity rating and can handle up to 100 watts of power on continuous basis. You can pair them up to your aftermarket receiver, but for the optimal results, consider feeding them plenty of power from an external amp.

If I had to pick some cons for these speakers, I’d say that despite being marketed for marine use, they’re lacking ASTM certifications for salt, fog and UV lights.

These are not by any means the best materials, however, they get the job done without costing you a fortune. That said the built-quality isn’t the best but the value for the money is great.
