How to Measure Marine Speakers

If you’re looking to upgrade the sound system on your boat, you’ll need to measure the marine speakers before you make a purchase. This will ensure that you get the right size and shape of speaker for your space. Measuring marine speakers is a relatively simple process, and only requires a few tools.

With careful measuring, you can be sure to find the perfect set of speakers for your vessel.

How to Measure for a Replacement Speaker.

  • Determine the size of the marine speakers you need
  • Use a tape measure to find the diameter of the speaker, and then add 2 inches to that measurement
  • Cut a circular piece of plywood or MDF that is this size
  • Trace the outline of the speaker onto the plywood or MDF, and then cut out that shape with a jigsaw
  • Place the speaker in the hole you just cut out, and trace around its perimeter with a pencil
  • 6 Remove the speaker and use a router to cut a groove around the inside of the traced line
  • The groove should be about 1/2 inch deep
  • 7 Place weatherstripping in the groove you just cut, and then place the speaker back in position so that it sits flush with the surface of the wood

How to Measure Speaker Size

If you’re looking to buy a new set of speakers, you’ll need to know how to measure speaker size. There are a few different ways to do this, and the method you use will depend on the type of speaker you’re looking at. Here’s a quick guide on how to measure speaker size:

For most stand-alone speakers, the size is measured in terms of diameter (across the front face of the speaker). For example, a common bookshelf speaker might be 6.5 inches in diameter. If you’re looking at in-wall or ceiling speakers, the size is generally given as the cutout hole diameter that’s required for installation.

For example, a popular in-wall speaker might have a cutout hole diameter of 8 inches. When it comes to car speakers, size is usually expressed as an overall width measurement. For example, a common car speaker might be 5×7 inches wide.

Now that you know how to measure speaker size, it’s time to start shopping! Keep these tips in mind and you’ll be sure to find the perfect set of speakers for your needs.

How to Measure Marine Speakers


How Do You Measure Marine Speaker Size?

When it comes to marine speakers, size does matter. But how do you measure marine speaker size? The first step is to measure the diameter of the speaker.

This is typically done in inches, and the measurement should be taken from the outermost edge of the speaker. Once you have the diameter, multiply it by 2 to get the circumference. Next, you’ll need to determine the depth of the speaker.

This is usually measured in inches as well, and again should be taken from the outermost edge of the speaker. Keep in mind that marine speakers are designed to withstand being submerged in water, so they tend to be deeper than regular speakers. Now that you have both measurements, you can calculate the total volume of your marine speaker using this formula: V=C*D*0.7854 .

The result will be given in cubic inches (in3). For example, a 6″ diameter x 8″ deep marine speaker would have a volume of 301.44 in3 . Once you knowthe volume of your marine speaker,you can choose an amplifier that best suits its power needs.

How Do You Measure the Size of a Speaker?

When it comes to speakers, size definitely matters. But how do you measure the size of a speaker? Here are a few things to keep in mind:

1. The size of the speaker is determined by the diameter of its driver. This is the part of the speaker that actually produces sound. So, if you want to know how big a speaker is, simply measure the driver.

2. Another important factor to consider is the depth of the speaker. This refers to how far back the driver sits within the speaker cabinet. A deeper speaker will usually have a fuller sound, while a shallow one will tend to be brighter.

3. The final thing to think about is power handling. This has to do with how much power (measured in watts) a speaker can handle without being damaged. A larger speaker can typically handle more power than a smaller one.

Keep these things in mind and you should have no trouble measuring the size of any speaker!

What Size are Marine Speakers?

Marine speakers come in all different shapes and sizes, but the most common size is 6.5 inches. Marine speakers are designed to withstand the harsh elements of the outdoors, so they tend to be a bit more durable and weather-resistant than regular speakers. If you’re looking for marine speakers that will provide great sound quality, then you’ll want to make sure to get ones that are at least 6.5 inches in diameter.

How Do I Match My Marine Speakers to My Amp?

When it comes to marine speakers, there are a few things you need to take into consideration when matching them to an amplifier. The most important thing is the impedance of the speaker. This is measured in ohms and is generally printed on the back of the speaker.

Most marine speakers have an impedance of 4 ohms, but you may also find 8 ohm models as well. It’s important that you match the impedance of your speakers to your amplifier. If you have four 8 ohm speakers, for example, you would want to use an amplifier that can handle 8 ohms.

Another important factor is the power handling of the speaker. This is usually expressed in watts and tells you how much power the speaker can handle before being damaged. Once again, it’s important to match this rating to your amplifier.

If you have a 100 watt per channel amplifier, then each of your speakers should be able to handle 100 watts as well. Finally, you’ll want to take into account the sensitivity of your marine speakers. This is measured in dB and tells you how much sound pressure level (SPL) the speaker produces with a given amount of input power.

The higher the sensitivity rating, the louder the speaker will be with a given amount of power from your amp.


If you’re looking to buy new marine speakers, it’s important to know how to measure them. Here are a few tips: – First, take a look at the size of your boat.

This will give you a good idea of how big or small your speakers need to be. – Second, consider the type of music you typically listen to and how loud you like it. This will help determine the wattage and number of speakers you’ll need.

– Finally, think about where you want to install your speakers on the boat. Once you’ve considered all of these factors, you’ll be able to narrow down your options and find the perfect marine speakers for your needs!
