If you need to replace a speaker, it’s important to measure the correct size to avoid buying the wrong one. The size written on the speaker may not necessarily be the actual size, so don’t assume that the measurement is correct. In this blog post, we’ll show you how to properly measure for a replacement speaker so that you can feel more confident that you’re getting the right size the first time.
First, check to see if the hole where your speaker will be placed is recessed or if it will just sit on the top. If it’s recessed and needs to be flush, measure the actual hole and the larger cutout around it from side to side in inches. Make sure the smaller hole is greater than or equal to the baffle cutout diameter and the larger cutout is equal to the overall outside diameter. If you’re doing a surface mount, measure the hole and make sure it is greater than or equal to the baffle cutout diameter on the speaker. Also, make sure the overall outside diameter is greater than that measurement or it will fall through. Keep in mind that it can be too big as well. If it’s going to hang over too much or cover the other portions of the speaker, it’s not the right size.
For example, if you have a recessed hole, you’ll need two measurements: the outside diameter and the inside baffle cutout diameter. Let’s say the outside diameter is 6.5 inches, and the inside baffle cutout diameter is 5 and 5/8 inches. It would be helpful to look in the six-inch range for a replacement speaker since you know the general size, but since all products have exact specifications, you need to find one that matches up exactly. The DC 160 – four is the perfect size for this cabinet.
When replacing a speaker, there are a few things to keep an eye out for. First, make sure you have enough room to fit the speaker all the way into the cabinet. Second, make sure you know what impedance to be here you’re buying it maybe listed on the rear of the magnet or possibly even the backside of the speaker as normal impedance. Finally, don’t buy a round speaker if your hole is not round – there are a few different shapes, and the general rule for measurement is flat to flat.
