Product Description

Product Description

Water Resistant

But not water proof. There is a difference between the two. Since the MR690 lives near the water almost all the time, all of the major components such as the spider, surround etc. have been specially coated to have the protection that they need from corrosion that is present in a humid and salty environment.

Specifications
  • 6 x 9 inch 2-way Marine Speakers
  • Peak Power: 350 Watts
  • RMS Power: 175
  • Impedance: 4 Ohms
  • Frequency Response: 60Hz – 20kHz
  • Sensitivity: 92 dB @ 1 W/1 Meter
  • Mounting depth: 3-3/8”

Cone – Poly Injection

Polyurethane is a resilient, flexible, and durable manufactured material that can take the place of paint, cotton, rubber, metal, or wood in thousands of applications across virtually all fields. It can be hard like fiberglass, squishy like upholstery foam, protective like varnish, bouncy like rubber, or sticky like glue. In the specific case of our cones, this material allows for maximum flexibility that produces great sounding speakers lasting you a long, long time.

Tweeter – Mylar

For a modern edge, the best car speaker could be the high tech Mylar tweeter, as it generally has more ability for a wider variance of sound modifications and channel handling. Unlike paper cones, the Mylar has a higher rate of durability, as the cone is made of a plastic poly material, which does not rip or tare easily, under abnormal frequency changes.

Surround – Rubber

Rubber is a synthetic material valued for its chemical inertness, impermeability to air, and the ability to endure or resist exposure to the many types of weather fronts. Rubber has applications from Sports equipment to automotive parts, the medical industry, and more. We use them for the Surrounds that connect the cone to the basket. Did you know that most modern chewing gum uses food-grade rubber as the central gum base, which contributes not only the gum's elasticity but an obstinate, sticky quality? Just like that chewing gum, the Rubber Surround in our speakers can take the equivalent amount of abuse without quitting on you.

Voice Coil – Aluminum

One of the most abundant elements on earth, Aluminum is remarkable for its low density and for its ability to resist corrosion. It is nonmagnetic and does not easily ignite. This solid material has the ability to perform under stress in both high tension and high compression environments. Aluminum is relatively soft, making one of the more ideal materials to use in voice coils.

Installed these in my 25' open cockpit boat this past summer.

They WILL provide decent sound quality for an open boat. What they WILL NOT do and CANNOT do is replace larger cone/heavy sub-woofers, etc.

Here's my point. Some people expect a 6X9 speaker to fill a boat cockpit like it can fill the inside of a car, and if you walk in expecting that, you're going to be sorely disappointed with any 6X9 speaker. Sound bounces around and fills areas of a car cabin while it "falls apart" much more readily in the open space of a boat cockpit.

Why the speach? Because I've seen some reviews that sorta "panned" these speakers when the problem was more likely unrealistic expectations on the part of the reviewer.

Long story short:

If you are looking to make your boat ROCK with a LOUD sound system that just HAMMERS out the music and THUMPS out the bass without a bit of issues whether at the dock or going across the lake then go get a THOUSAND (or more) dollars and build a SOUND SYSTEM that can do that.

If you want a set of speakers that can provide some decent music to your dock-side or fishing experience without breaking the bank, and understand that you can only push so much air with a 6x9 cone, then these speakers are just what you need!

These 6x9's are a great value for the $$$. They outperform competitive speakers selling for three and four times the price. As with all speakers, the final sound is dependent upon the speaker enclosure, so make sure you have good enclosure volume to get the most out of the low end. Two up front and two in the stern and your 20 ft. to 30 ft. boat will have a very nice sound system.

I am sure many return half the order as it reflects speaker when in fact it is two

Recently replaced existing pair of blown 6x9 speakers in fishing boat. At basically $30 each (I pd. $57 for pair) I was not expecting great sound, just better than blown out speakers. The grills on these are pretty flimsy; if mounting where they could get kicked I'd recommend something with a stronger face plate. Sound quality is OK - definitely not JL - but also not JL price. And these are really WHITE - way more white than any white gel coat. So if you just need a low-cost replacement (all I needed) to last a season, this is it. If you are an audiophile, you will not be happy.

I put a pair of these in an 18' Caravelle boat and they sound great. System includes 2 Boss MR50W 5.25-Inch 2-Way Marine Speakers, 2 Boss MR60W 6.5-Inch 2-Way Marine Speakers, Boss MR690 6" x 9" 2-Way Coaxial Marine Speaker hooked up to a MB Quart Marine NAU460 180-Watt A/B-Class 4-Channel Amplifier. Also have a Bazooka MAA1500 500-Watt Marine Mono Amplifier hooked up to a pair of Boss MR100 10-Inch Marine Subwoofers and I couldn't ask for a better sounding system. These Boss speakers may be cheaper than the other brands but they sound awesome.

After reading plenty of other reviews, I decided to purchase a pair of these speakers for my boat and see if everyone was right. I am very happy to say they are great for the price! Sound quality is as good or better than a more expensive, typical name brand speaker. I'm buying another pair for the front of the boat. We'll see how long they last.

Arrived quickly, installed easily (holes lined up with holes from prior west marine speakers). Works fine, only question now is how long will they last and how water resistant they are

Great speakers for the price, well made for the marine environment. They sound awesome, I have 400 watt and they take all of that power and still have a crisp sound
