(7)Is BH (backing loading horn) musical instrument system?

  I thought that I became a speaker where the horn speaker (backing loading and [furontoro-do]) had both a lot of elements of "Musical instrument system".


  I will quote it here though it has thought of this for years so because the backing loading of [furontoro-doho-n] and Nagaoka [tetsuotoko] of the woodwork system is heard even if the tannoy is heard or a metallic horn is heard because there were sentences to explain it in a very comprehensible word.

�(omission)Therefore, the difference between a sound pressure level of the sound radiation in the cabinet and a direct sound pressure level of the sound of the speaker contracts more when it is near when hearing it in a point several m away from the speaker. The more remarkably. larger the opening of both is the surface area of the cabinetYou may possibly think the sound radiation to be [karaderu] of the entire board so-called surface sound source of the cabinet.

  It is very made the consent of the target because of an attached expression. Perhaps, because the surface area of the enclosure is the largest in the speaker system that can think, backing loading horn : in a word. (The size might by about the twice usual [basurefu] be the same) Because of idea that they more than a usual speaker influence the reverberant sound, and the enclosure gives birth to a fresh sound of the stringed instrument not usually thought about. It can be said a natural result when thinking the person who makes backing loading horn has a strong sticking to in the material of the enclosure there.
