Polk Audio DB651 Marine Speakers

Declared one of the best Polk Marine speakers, this 6-1/2″ / 6-3/4″ 2-way coaxial speaker set has all that it takes to make it stand out. It may seem a little tiny in size but do not judge it from its size as it offers what some even large speakers fail to.

It has an ideal amplified power giving out the peak power of 320 watts per speaker, and RMS 120 watts/ speaker. What these measures basically suggest is that the speaker is capable of giving out an excellent sound quality, enriched with deep bass. It shall also help to save up a lot of electrical cost as it won’t need too much current to operate on.

Furthermore, as it is a coaxial speaker, and what makes it different from regular speakers is that it has a tweeter incorporated into the speaker. The tweeter lies either on bridge above the woofer or on the pole in the center of it. This saves you from allocating any additional space for subwoofer or the tweeter.

Moreover, the tweeter it has is no normal tweeter. It is a 3/4″ Liquid-Cooled Silk/Polymer composite Dome Tweeter, which is the best tweeter in market. It shall increase the frequency response of the speaker and minimize any sound distortions when at full volume. It shall also prevent the speaker from heating up every now and then. Hence, making the speaker a lot easier to handle and long lasting.

Also, it has a polymer/mica composite mineral filled cone woofer, which is rust and heat proof. This is one the reasons which makes this speaker perfect for your boat. And not only this, but it is also marine certified, which will sit perfectly for your boat.

Things we liked:

  • Coaxial
  • Polymer/mica woofer (perfect material for marine speakers)
  • Lightweight
  • Liquid cooled polymer tweeters

Things we disliked:

  • None.

Factors to consider before purchasing Marine Speakers

It is not every day that you buy speakers, so why not get one that serves you right? You will definitely want one that gives out an amazing sound quality and stays with you for a good time. Now, we know it might get a bit frustrating and hectic when you hunt for the best speakers. So to save you from this pain, we have boiled down a list of all the important factors you must consider.

1. Sound quality:

It is a must to check for sound quality. With all the noise and nuisance at sea, you would want a speaker that gives out crisp and clear sound even at high volume. Now you can determine the sound quality empirically or just by looking at the Watts, Decibels and Frequency response. To even ease up the process for you, here is how these 3 measures help you in determining the sound quality:

Frequency: It tells you about the area your speakers can cover up. The higher the frequency response, the better the speaker is likely to be. It starts from as low as 20 Hz and goes up as high as 20kHz. The ideal speaker will be one with the frequency response of 50Hz to 20kHz.

Watts: They act as a measure of the speaker’s maximum amplified power. The greater the Watts, the better the speaker will work for you.

Decibels: They show how effectively can the speaker use the power from the amplifier. A higher rating would point toward a better sound quality with minimum distortions and deep bass even at full volume.

2. Impedance:

Measured in Ohms, it determines the ability of the speaker to let the electrical current pass through it. There are basically 3 impedance levels being 4,8 and 16 Ohms. To get the best out of your speaker and consume energy go for either an 8 or 16 Ohms speaker.

3. Hertz:

It is measured in Hz and they suggest the sound, particularly the bass level of your speaker. Unlike most other factors, the lower the Hz is, the deeper bass will the speaker generate.

4. Durability:

This matters a lot as you would not want a speaker that will break just within a year or even before that. A good speaker calls for longevity. So make sure to check for that.

5. Sensitivity:

This determines the amount of power your speaker needs to power on. The higher the sensitivity level, the more effective the speaker will be.

6. Texture of the speaker:

It is best to get a marine speaker that fights up to all weather conditions, no matter how harsh. The better the texture, the better the material used, the longer the period will your speaker serve. It is recommended to get a speaker that has a rubber surrounding and the outer body is made in either plastic or polymer. These materials are considered the best for marine speakers as they protect the speaker from all harsh conditions and add to the durability.

7. Material of the woofer:

It may seem a bit irrelevant, but it is very important to check for it as well. Like watts, decibels etc. material also affects the effectiveness of the woofer. To keep it short and simple, the lighter the material is used on the woofer, the greater the bass will the speaker generate.

8. Size of the speaker:

This happens to be an extremely important factor when it comes to best marine speakers. You need to get a speaker that perfectly fits in your boat or there is no point of the purchase. Since boats are usually not that large, so a speaker of somewhat around 6×9 inches will do just fine for you.

However, do not limit your options, these speakers come in various sizes. Just make sure they are not too big for your boat. But also, bear in mind that typically smaller sized speakers give out a slightly inferior sound quality than large speakers. But there are anomalies too, just get one that matches all your needs.

9.Magnetically shielded:

This is important because the magnets in your speaker may interfere with the navigation of your boat. So to steer clear of that look for a speaker that is magnetically shielded.

10. Color and style of the speaker

This happens to be your very personal choice. To your benefit, marine speakers come in a number of different styles and colors. So just pick one that blends well with the interior of your boat or in fact, adds color to its elegance.

Advantages/Disadvantages of Marine Speakers:


  • Water-resistant: With these speakers installed in your boat, you won’t have to worry about the water hitting them. And by water-resistant we do not mean splash resistant but they are also submergible in water.
  • Rust proof: They have been designed to encounter any rust and salt corrosion in the sea. Hence, making them last longer.
  • Prone to harsh conditions: It is clear how harsh the weather can get at sea. There can be series of high velocity wind storms and rainy days. But what is great about these speakers is that they will work just fine no matter how bad the weather gets.
  • Different styles and colors: As mentioned above, marine speakers like most speakers come in various colors and designs. Hence, making it possible for you to choose the one that goes best with the interior of your boat.


  • Smaller in size: These speakers are usually smaller in size than the regular speakers. This may mean that they can’t give as excellent a sound quality as do regular speakers.
  • Smaller tweeters: This may mean that marine speakers have lower frequency responses than regular speakers.
  • A little harder to install: They may require 6 mounting halls than the standard 4 holes. Hence, making the whole installation a bit cumbersome.
  • Lack of positive and negative markings.
