This Web site is for audio amateur craftsmen and music fans. I am neither a professional craftsman nor a professional audio designer. However, as I have some audio experiences and struggles with following woods related topics, I would like to share such experiences & struggles with persons interested in the same subjects:

Wood horn speaker design and handicraft
Loudspeaker design and handicraft
Measurement of speaker system properties
Others

You can see most above topics in the Japanese magazine, the "Audio Technologies" shortly called "MJ", published by Seibundo Shinko-sha located in Tokyo.

Wood handicraft activity is very interesting subject in itself. At the same time, as loudspeaker system is for listening music, the system need to be carefully designed and made, with the properties be measured precisely and adjusted accurately. Further, along with speaker system properties, room acoustics is a very key as well. I would like to touch on those subjects.

Finally, for general guideline of this Web site, I would like to ask that first all you you see "Preface" before you get into each subject on this Web site. I would be very happy if you enjoy my site.

Important notice-1: You may refer drawings on this Web site if you like, in order to make your own speakers. Please note, however, that the performance is NOT guaranteed in any ways.

Important notice-2: Some of the measurement data are not so accurate because of the reasons that I could only use a 8 bit AD converter in early personal computer age when I collected those data and, one more reason that, to my great regret, I have not have anechoic chamber at my lab. If you start now you are lucky because in recent days, very high performance personal computers are available everywhere, and now you can find very good freeware and/or shareware to design and measure speaker system properties. Accuracy of data is much better now. I really feel that today's circumstances are not what used to be.

Notice-1 : Please send your messages/comments either in Japanese or English. There might be the case that I can not respond to you so quickly, but please be assured that I definitely read all the messages/comments I receive from you all and, if applicable, feed back them at the next update of the Web pages.

Notice-2 : Please understand that this Web site building is my step by step activity and not completed yet. At the present moment, accordingly, only several items/topics are available. You can expect to see the rest of them, and also my future audio works.

Notice-3 : Please understand that since English is not my native language, this Web site may contain some unfamiliar words/ sentences to you. If you find ones, please inform me.


Thank you very much for your attention. Yuichi Arai
