Since I made the small version of ALTEC last time, and there was very much good sound, I contacted my friend. Immediately, he came to my house, and he thought well. Since he wanted to use for the speaker of a radio cassette recorder, he wanted to me to make a smaller one. Since I can make it from the remainder that was made last time, I made instantly.

I used the inner unit in a 5 inch national full range. Although sound was so so, I think it is very pretty. (Photograph)
I thought that I would make my own speaker with a baffle board, and I made from the 36mm plane of a maple tree.
I do not like big size, So I made smaller one, When I sounded, low-range was slightly short. As a result of making it a L type or repeating an experiment many time, I completed this speaker.
The best speaker unit is the 8 inch full range of Victor that I bought it by Hi-Fi-Do before. It is the result of exchanging three units. I found well that sound is considerably different not for the unit but for the baffle board size. Although the larger one was good, since I need the bigger place, I devised many things.
