How to choose plywood
Nagaoka [tetsuotoko] teacher's self-made speaker bonds the cut wood with the bond by putting the potato. It is necessary to choose which wood first of all ..whether buy it... Any wood can be used variously and basically as a material of the speaker such as the purity material, the laminate lumber, and plywood even if it says to wood and the unit.
"Plywood" that the Nagaoka master also most often used will be used here. Then, what kind of plywood is used for the speaker construction?There are too not a lot of kinds of plywoods as for the one that is liked and used for the one and the speaker construction that can be obtained in the do-it-yourself store etc. though are numerous the kind either.
| Kind | Price | Feature |
| Lauan plywood | - - | It is divided into a red lauan and a white lauan when dividing it roughly as the lauan has a great choice. The specific gravity of the red lauan is heavier. As for the appearance in the do-it-yourself store, there are a lot of "White lauan". When painting is given, it is hurried taste [gaderu] though externals on the surface are not too good. Recently, the price has gone up. |
| China plywood | - - - | Plywood that put sliced veneer of thin China on surface of lauan plywood. When externals are excluded (Under the influence on the sound), you may almost think the same with the lauan plywood. The surface is beautiful in white. The urethane painting etc. of clearness are suitable well. [Zai] that obtains easily most and is general. |
| The wick plywood both of China. | - - - - | Plywood from which all sliced veneers on surface and inside part of accumulations are made in China. Because the lauan or China's specific gravity is light, tone quality has the possibility of becoming a soft sound without the wick. However, the part of accumulation (quality of timber used part) is more beautiful than the China plywood on. |
| MDF | - - | The one that pulverized what tree is crushed was hardened. The specific gravity is heavy. Most of a speaker on the market uses MDF of custom-designed. It is possible to obtain it easily in the do-it-yourself store. There is an utility value so as not to add the sound of the box though the sound of the tree is monotonous. The quality is far more uniform though it is uneven to the specific gravity by [zai] compared with the lauan. |
| Lumber core plywood | - - | The lumber core plywood is plywood that packs the chip into the inside and is made. If the sliced veneer of China is a lauan lumber, the sliced veneer of the lauan is put on the surface on the surface if it is a China lumber. This is almost used for a general furniture making, and I also use it on business every day. Lightly, and the specific gravity is too good and arduous to be suitable for the speaker enclosure. |
| [Shinaapiton] plywood | - - - - - | The [shinaapiton] plywood is sticking of [apiton] on the surface in the heart wood to the piercing board of China together. Because the specific gravity is heavy, and the part of accumulation is beautiful, it is very popular. However, the price is also very expensive as well as [finrandoba-chi]. |
| [Finrandoba-chi] plywood | - - - - - | The price which the price is the twice China near in which it was being used by Nagaoka master's Nessie though it makes fun and there is very popular. It is a feature that the part of accumulation is very beautiful a lot compared with the lauan. the number of sheets of accumulating (It is called ply)The sound of the high pitched sound is beautiful. |
