How to Measure Speaker Size?

I think you want to learn how to measure speaker size?


In case you have older speakers and you need to change them, then you should purchase the speakers which have a similar size because they can install easily.

Sadly, there aren’t standard sizes for the speakers, therefore the listed measurements may change from what actually required.

Measure the height and diameter of the speakers therefore you are able to search for new speakers that suited the measurements.

If you just have mounting holes for going off, measure them completely so you are able to get speakers which will be able to fit in space easily.      

Method # 1

To Measure the Speakers Dimensions

Take out a speaker from the housing. Remove every cover in the front of the speaker through either popping out of space or the unscrewing them.

Find the mounting screws on the front side of the speaker and then unscrew them utilizing the screwdriver. When screws are free then pull the speaker out carefully of housing then disconnect every wire of speaker attached to this. 

  1. Ensure your speaker is detached from the power prior you begin taking speaker apart. 
  2. Check diameter at the widest position of speaker’s mounting design. Utilize a measuring tape or a ruler to take the size in the inches for your speaker. Adjust the speakers upstanding so the widest piece of the cone is the face-up. Take the measurement at the widest dot of the speaker from a single edge of mounting structure to others. Record measurement therefore you remember this later on. In case you have speakers which are not round, measure the largest points of every side so recognize its every dimension.  

Tip: If your speaker just has 4-holes to mount screws and then measure the size from one of the mounting holes to single that is diagonally opposite it.  

Take the size for cutout diameter

  • Turn your speaker reversed so its widest piece of the cone is the face down. Its pattern measurement is the widest piece of cone connected to the rear of the mounting framework. Utilize your ruler or measuring tape for finding diameter at the widest point then record this so you do not forget.
  • If the speaker is not round, measure its widest spot from every side so recognize every dimension. 
  • Its cutout diameter should be little or similar size as hole wherever you plan to install your speaker.  

Measure its height from the rear side of the speaker for mounting frame

Set the speaker so wide piece of the cone is the face-up once more. Start the estimation from the base of the speaker up to flat plastic piece or the metal around the cone, moreover called mounting frame. Record the measurement that you took therefore you remember this.

If you have a too tall speaker for space where you want to put it, at that point this will not sit flush or this might get harmed when you attempt for inserting it.

Determine the speaker’s height which extends from mounting fame

Keep face-up to your speaker with the widest part the pointing up. Begin the measurement from the bottom of the mounting plate, plus check height between this and highest point of your speaker. Search at the speaker from the side, therefore, you are able to decide how far this extends up from the mounting frame.  

  • Its height which extends out from mounting plate is essential since the one which extends very far could get harmed and then bump into the things. Such as, if you have too tall car speaker, this could harm the cone if you near to the door of your car. 

Method # 2

Measure the Mounting Holes to Install New Speakers 

  1. Measure the external diameter of the mounting hole. Search for the widest part of the mounting hole then place a ruler across the hole. Get measurement in the inches from the one edge of the hole to contrary side directly across thus you know the higher size you are able to take for new speakers. Record its measurement so remember this later on.
  • The external diameter must be the similar size or slightly bigger than the mounting frame of the speaker
  • If the mounting hole has no round shape then verify its widest point on every side.
  1. Measure the internal diameter of the hole if it has recessed areas. Space, where you want to mount the speaker, might have a little recessed lip around the internal side of hole therefore mounting framework lays flush. Put the ruler on a side of the recessed hole then measure directly across to the opposite side of the hole. 
  • Not every speaker box has a recessed lip.
  • Get the widest point on every side in case you have speaker hole which is not round. 

Tip: If the speaker has recessed lip, at that point the cutout diameter of the speaker should be slightly littler or similar size or probably this will not fit in the hole.

  1. Settle on the depth of space where you are placing your speaker. Fix your ruler internal side mounting hole plus push this as far back as this can go. While you are unable to push your ruler any more, look at measurement for deciding the higher depth which you are able to get for the speaker. Whenever you buy a new speaker, ensure mounting height to be shorter than measurement.  
  1. Check screw design sp you are able to purchase speaker which are similar. Look at the design of your current speaker hole which you have and discover distance from one screw holes to other straightly across from this. Then check distances between other screws also record therefore you can evaluate pattern to some fresh speakers that you buy.   
  • You can trace the design of screws on the paper sheet therefore you have visual comparison when you go for buying the speakers.
  • The speakers come with screws for mounting required for securing in the place.
  • If you are unable to find the speakers which have similar screw design, you may need to drill new holes
