(1)Purpose of experiment
In the purpose of the experiment, it is a purpose to examine what influence goes out to the entire speaker system when "[Zai] of the enclosure" is changed.
If it met [gadekiru] difference [woshiruko] of the sound of the enclosure and result and following requirements of thinking if it did very, it thought whether attention was able to be compared the difference of the speaker enclosure.
- Only [zai] changes quite the same enclosure and two pairs (4 pieces in total) are made.
- Two units of quite the same unit and the same use condition (4 pieces in total) are used.
- How (woodwork bond, machine screw, acoustic material, and acoustic material) to assemble it is united.
- The surface area is good because the sound of [zai] is made comprehensible and the large one as possible is as good.
- It is a speaker of [wonakusutame] and one full cooking stove as for the error margin of the quality between the same parts. The network is not used.
- The comparison of [zai] that will make the difference stand out is as good as possible.
- Everything of course is measured with the same system in the test.
The speaker that meets the above-mentioned requirement is made, and everything is made the same condition excluding [zai] of the enclosure. If the sound has changed by this, it is assumed to be able to think to the one by "Sound of the enclosure" almost purely. The speaker that I chose to be an experiment is an one D-88 super-flamingo of the superman patient hill speaker that Oyama chose.
Let's easily do amplification though it is because of the good agreement with the condition to 1-7. "1" "3" is easy though takes time. The same two enclosures are only made by the same industrial method. The condition of "2" is loading one clearness and full cooking stove's backing by being able to obtain four FE-88ES of a limited unit and the condition of "4" and "5" is clear. The comparison of ..standing out.. [taseru] [zai] is ..pole power difference.. good. condition "6" andThe MDF material and the [finrandoba-chi] material decided to be used for this. Because the evaluation to MDF is too undesirable, the reason : while the [finrandoba-chi] plywood has been treated as uppermost plywood between self-made sects. If it was this, it was thought that the difference might be ..clearness.. [deru]. I am said, "[Ba-chi] is good" and "[Apiton] is good" all if it doesn't confirm it for myself by a sorry nature of the nature and am not very convincing until my experimenting and confirming it.
There are one point what cannot be done in the same way though only straightening tuned the condition this time. And, it noticed a big mistake have been violated when being think in the future. Because MDF and [finrandoba-chiba-jon] separately made it, it is a point that there are about one month time error margin in the completion. This cannot be considerably disregarded in a word because it can be said that the MDF version is in the state to which the aging of the box and the unit is advanced. Only the enclosure is helpless though it is possible to put together because the unit measures for [toki] ..seeming [souna] it... It pursues the subject probably for reflection to next time.
