Very cool work!

I use a wood surround and screws.I place the 4 wood pieces in place round the diaphragm cutout, hold them in position with 2 screws in each piece. I then pull the membrane and tighten the screw and work my way around a screw at a time till it feels like a drum skin, nice and taut all round. The consistency is due to your strength of pull, which is constant, so don't do it when you are tired or fed up!! It always gets looser when you run the speakers for a while. So you may have to do it again. Depends how keen you are and how picky you are as well. You could do it several times until you are satisfied, but I only do it once.Depends on the music you play how loud etc. Being in stereo you get different strains on the membrane, so you can't really hope to keep the membranes the same anyway!

Have completely changed my layout in the living room, and made more room.
