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 must 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.

Polk Audio DB692 6X9 marine Speakers ReviewNo 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″ supertweeters 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.

Infinity 6952M 6X9 Marine SpeakersInfinity is one of the most authoritative brands in the audio industry. They were founded in 1968 and have been part of the Harman International Industries since 1983.

Infinity offers a wide range of car speakers, however, as with most speaker brands, their marine audio products are slim pickings, with just a few models available in the marine series.

The 6952M speakers are the best 6X9 marine speakers that Infinity have to offer. These speakers are featured with polypropylene woofer cones bonded to a tough, UV-resistant rubber surround. This allows these speakers to perform quite well and deliver full bass response, while maintaining excellent resistance to UV light and moisture.

Additionally, the corrosion-proof, cast-polymer basket shrugs off deterioration caused by being in the open air, while the stylish non-removable grilles are specially treated to retain their bright white finish.

As for highs, these speakers use grille-mounted 1-1/4″ tweeters which offer excellent high frequency projection. Overall, the sound quality is pretty good. The 6952M speakers sound super clear and loud with well-balanced mids and treble.

Infinity 6952M marine speakers are very efficient speakers. They’re rated for 96dB sensitivity rating which is the highest among all marine speakers we listed here. This makes these speakers compatible with most if not all radio receiver out there. Combine that with their high RMS power handling rating of 100 watts and you get speakers that will make your boating experience the best it can be.

JBL MS9520 6X9 marine speakersJBL is one of the most recognised audio brands under the Harman International umbrella. They’ve been business for a very long time and have been been churning out quality speakers of different types.

The MS9520 is the best 6X9 marine marine speaker in the JBL MS series. These speakers are desgined 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.

JBL MS9520 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.

BOSS Audio MR690 6X9 marine SpeakersBOSS Audio MR690 speakers are a good, budget-friendly option if you want to upgrade the feeble speakers in your boat. Undoubtedly, you won’t get hi-fi quality from a set of marine speakers costing $40 or 50 bucks, but the BOSS Audio MR690 will do the trick if you need an affordable set of marine speakers.

These speakers are featured with polypropylene woofer cones supported with treated cloth surround. These babies can deliver some excellent bass output. Obviously they don’t hit like a component system with a subwoofer, but they’re very much adequate.

Despite their relatively low price tag, these speakers can sound relatively well compared to factory speakers. They sound satisfactorily loud and clear without much distortion to speak of at mid-upper and high volume.

The BOSS Audio MR690 speakers speakers are rated for 92dB sensitivity rating and can handle up to 175 watts of power RMS.

If you are a serious audiophile looking to make your boat ROCK with a premium, customized sound system that just hammers out the music and thumps out the bass whether at the marina or saling across the lake then go spend thousands of dollars and build a sound system that can do that.

However, If you want a set of speakers that can provide some decent music to your dock-side or fishing experience without breaking the bank, then these speakers are just what you need!
