How to measure ceiling speaker size.
At crutchfield, we help customers who have questions about car speaker size all the time.
A single stereo speaker will be enough for you(examples:
If the speakers are 10 feet from your chair, place them no more than 10 feet and no less than 5 feet apart from each other to maintain a good stereo effect.
The box should be a very tight fit for the speaker itself to go inside.
A single speaker can be one size for installation purposes, another size for the purchase of a repair kit, and yet another size for expressing potential power.
What you need to measure is the diameter of the main circle of the speaker in which it becomes the main part that produces the audio.
So, you can measure its diameter.
If you understand typical speaker dispersion profiles then you’ll know that very few speakers have such wide coverage.
Measure the distance from the speakers to your chair in a level, horizontal line — i.e.
Place it win the center of the ceiling.
Larger diameter speakers will often require deeper depths due to the cone of the larger bass driver extending further back.
Click and drag the edges of the speaker box, or type in new values in the width, height, & depth fields.
The height/depth of the speaker is also worth considering.
Required coverage / dispersion, speakers pointing straight down.
Varies with the room size.
With the speakers pointed straight the front atmos ceiling speaker must have consistent coverage out to ~70 degrees off axis!
You always measure the hole where the ceiling speaker is to be mounted.
The size of a speaker can be expressed in different ways that depend on the purpose of the measurement.
The most important step to get right is correctly measuring your speaker placement and hole size before cutting.
Figuring out car speaker sizes can be a little confusing.
