You can either build or buy your own speaker enclosure. You save money by making your own, but if you’re not a craftsmen or don’t have the time, you should buy one. Regardless, the foundation of what makes a solid speaker box will never change. Here’s what you need to know.
The speaker enclosure itself has to be made of Medium Density Fiberboard (MDF). If you’re looking for a shortcut or something cheaper, don’t do it. MDF is somewhat like particleboard, because the wood fibers are glued together. The density of the wood, however, is much denser, harder and stiffer. MDF will not warp and can take screws being removed or screwed in without the fibers becoming loose. Most importantly, it will not leak your precious bass, preventing any flexing. Look for something with 5/8″ thickness. 1″ is mostly used for bigger speaker enclosures.
Don’t overlook the importance of how the seams of the box are connected. Good enclosures should be constructed using a full “U” channel Dado joint and mitered edges. Dados strengthen the side panels of the box, reinforcing the construction and seals. It’s not easily visible from the outside, so confirm with a “honest” salesman. A mitered edge, a 45 degree cut on both ends that form a 90 degree right angle, reinforces the corners of the box. This can be noted with a quick glance but run your finger along the edges to make sure it feels secure. All our Atrend speaker enclosures are constructed with full channel Dado joints and mitered edges.
Understanding the basics for a well constructed speaker box will help you make the right decision when buying or making your enclosure. Make sure the foundation is on firm ground. Simple changes, such as customizing your box or swapping out the subwoofer, are easy enough. You’ll be stuck, however, if you find out later the material is too thin or it’s not constructed properly.
Learn the basics. Your ears will thank you later.
