  A unit is FE83E and a front is Nessie Min, and D-118 and a super swan.

Since it of a man is also only a maniac person when it is
       called a handmade speaker

 I want to make such a dear speaker from a family very much.

 When small to it, a handmade speaker is known from from, and they are the
  beauty of sound, and low-pitched sound.

 Since it is not settled with , for prudent work, use of necessity and is size.
 The accuracy of bucket is different.

 Although the point of work of a resonance pipe is that there is no crevice
