(9)Supplementing and recently, is [ba-chi] (birch) boom?

It doesn't limit to the self-made speaker and [ba-chi] is recently also between speakers on the market like a kind of boom.


Pioneer's TAD REFERENCE ONE pair six million yen

Was firebrand's of this boom [ba-chi] such more major than it from former though the nature like Nagaoka [tetsuotoko]'s F-3000 Nessie �V did as [zai] of the speaker enclosure?

  A lot of plywoods that use the purity material and the purity material are used for a part of super-high-level speaker though the one to coagulate the one that the wood that was called that most is a fiberboard (MDF [pa-chikurubo-do] composition board) was floured once with the bonding material occupies the majority to the one of the low price of a speaker on the market. However, it seems to adjust the sound mixing the above-mentioned fiberboard with plywood that uses the purity material when the catalog etc. are actually seen. It seems to tend to turn on [zai] high-level like a rich speaker of the music character (musical instrument speakers), and to harden the cabinet solidly generally with a fiberboard heavy like the speaker (mechanical speaker) that is called a so-called monitor system. (However, indiscriminately also because TAD Reference One etc. of the pioneer put on the market recently are the monitor systems that aim at "Make of the cabinet no resonate" though it is not possible to say. )
When enumerating it as one example

Tannoy Cantervury�� walnut is pure.   (pair 2.1 million)
Tannoy yorkminster�� [ba-chi] plywood(pair 1.79 million yen)
Al Tech A7�� Canadian pine
TAD Reference One�� [ba-chi] plywood and MDF(pair six million yen)

  It is not certain in a super-high-level speaker whether [zai] is used because it doesn't open it to the public in how much ratio based on material with me. detailed the situation of [zai] that internal uses the speaker written here displaying [tsukawareteiru] [zai] (Also because this is my theme, I want to bring it together in the shape arranged once)It might be certain that it is the cause only though the expensive one might not be used for [zai] of the enclosure of course in the speaker expensiveness like this. ..[un].. ..1/10.. no of these speakers is one of the advantages of the self-made speaker be not able to used [zai] of a similar enclosure by the price of [un] 1/100?
