Too busy at the moment trying to make my final designs final and the best I can manage.Have several ideas floating around inside my head, will have to see how things go. I have a re-build using magnetic tape to do. I got some more MDF from my grandsons old bed. So will have to think about various designs, although I have several more re-builds to do with my 60 x 40 mm designs.The magnetic tape designs have worked out quite well and cheaper magnet wise. Still life and ideas in the old dog yet! The only problem is lack of space, rapidly running out. Plus the fact I am learning all the while, improving things by building and listening! Some unexpected some not.It's a big learning curve and I think I am on the lower slopes!!!

which is also why I thought smaller stackable modules could be 'convenient'

by 'small' meant something like 7 x 12 inches

but also means you would have to repeat the same more than once
which does not seem like your favourite thing

I have built a couple 12 x 8" speakers but the work involved is even more than building bigger ones, I am quite happy to build only 60 x 40 mm ones using neos and build slightly bigger ones using ferrites. This is the best way for me. Have built bigger ones 7' x 2' using neos. I am also interested in using cheaper magnetic tape having built one about 34" x 18". Which was a surprisingly good sounding design which was a big shock as I didn't think it would be, you live and learn. Still that's part of the enjoyment.

Default NEW DESIGN TRIAL

Have decided to try new design with about 3.9 mm gaps between the magnets, my son using some software worked out the gap size for improved sensitivity. We shall see, or not. Will use 3.9 mm wide plastic strips too keep the magnets apart. If this is a lot better, it will mean a lot more re-builds and more magnets to build more speakers. Wish me luck, and keep your fingers crossed, my back doesn't give in!!!
