Ah yes! They would be a superb project for someone handy. As I said though, the heavy brass cones are crucial. I was worried about the pointed top of the cone marring the bottom of my speaker so I placed a small piece of cardboard between the speaker and the cone and I was astounded at the loss of bass frequencies. The wood part would definitely be easy for anyone with the tools and you could always buy the cones from Mapleshade. They're not too expensive. The results will be worth it.
