If you want your woodworking to be heard….try speaker building.

This is a 3 way system that has just been finished. It has a woofer for low, a mid range for middle, and a tweeter for high frequencies. The crossover sends the correct range of frequencies to each speaker. Looking at the second picture notice the hole has been rabbited. Allowing the speaker to be flush with the surface improves performance.

Picture 3 shows the boxes build from 3/4 inch MDF, glued and screwed together to get an airtight enclosure. You can use solid wood or plywood, but I like the higher density of MDF, which helps on the sound I believe.

Looking at picture 4. notice additional bracing has been added to large panels to cut down on vibration. Wiring done with crimp lugs, and later acoustical fiberglass is added to inside.

If these speakers were going into normal operation, they would have been veneered and grill cloth added. However, they are to be mounted in a wall, so they are painted and fiberglass screen is used for the grill

Speaker building can be a lot of fun. If you look at the web page of my supplier,, you will see many types of designs under the speaker project page. Also they have information, like the golden rule that I used to size these enclosures..

Here is hoping that your next project will not only look great, BUT WILL SOUND GREAT!

They look great and I never knew so much went into making a speaker box. This is all I have on the addition wing to my shop, not nearly as impressive but it was cheap and works. (Laughing)

Yay! Another speaker project! Nice work!

Speaker-building got me into woodworking. I agree that Parts Express is a great resource for speaker building. They have lots of existing designs and have excellent customer service.

I encourage all LJs to give it a try. It’s very rewarding and you will find that better sound leads to more involvement with music.
