Domination of Swan speaker verification 2

Basal condition + MDF cabinet + FE108SUPER

  The Swan speaker is a very excellent speaker. It is a large problem of no limit to making by oneself and related to the advancement of the speaker enclosure to clarify "About why why does this original shape speaker have ability like this?" [korewo]. I think that the element that cannot be explained by two points (the point sound source and the backing loading) alone is too a lot of of the Swan speaker. Let's think about elements other than five features of the Swan speaker that Nagaoka [tetsuotokoshi] described here. There is a possibility of made a mistake in a selfish it hypothesis of Oyama as for this enough.
  As for the horn speaker, that [furontoro-do] makes the vibration of open regio oralis of that horn (If it is a part, and D-55 of hips, in case of Swan, it is a part that becomes like the previous trumpet) the intensest in the backing loading. If this raises the volume, even I can confirm at once, and a modal analysis has been proven becoming like that. Therefore, the speaker that raising strength in [kuchi] part having the horn in the design of the horn to the suppression of the bark of the horn was necessary, and announced at Nagaoka master's latter term is numerous the example of giving reinforcement by piling up two bottom plates.
  However, an easy imagination attaches to transmitting it it is not possible to avoid to the vibration board of the unit naturally, and causing the tone quality deterioration by transmitting the vibration to the entire box still no matter how it reinforces it. Are not you because the Swan speaker is far away of the vibration of the bark of the horn from the unit by the arrangement of the unit and the horn opening in the diagonal when arrangement is seen because it is more advantageous than other speakers in the meaning (ten-centimeter unit [karaderu] convex sound) called the vibration measures of the unit?The horn opening and the unit are adjacent up and down though the CW type of the D-55 faction has been considerably reinforced. The beauty of the convex sound of the fact Swan speaker is more overwhelmingly than other CW types on. (Though point sound source's effect to say nothing of it might be larger. )
