(4)Special comparison of f by pink noise
[Hikaku] is done by first of all usual attention comparisons of Nagaoka [tetsuotoko] drinking ..doing.. ..f.. ..special... Here is referred to because it is quite the same as the usual one and I would like a basic condition of the measurement. It went for making to correspond perfectly thoroughly strictly at the position of the speaker (distance and angle from the mike) in this comparison because it was the same speaker. And, because it was possible to measure it at the same time, it is likely to become the accurate data considerably in the meaning of comparison of both.
As a prior expectation, it was my expectation to say that it was not the change by the influence on data on the frequency response though whether big different [gaderu] was the enjoyment. the [ba-chi] plywood and differed about the MDF plywoodOn the audibility, they are these two quite different speakers. Though the high region level possibly thought that [finrando-ba-chi] might go out as some is high. The result : as follows.
D-88 made of [finrandoba-chi]
D-88 made of MDF
[Finrandoba-chiba-jon] on. The under is MDF version. As ..minor.. point though the substantial change was not seen on f special according to the expectation
- Depp of [ba-chiba-jon] of 400hz is fewer. The reason is uncertain. It is forecast it is almost flat in the speaker unit because this vicinity of 400hz is almost corresponding to the position in which fixed [ha] of the calculation upper part shop lives happens.
- The level of a high region has not gone out on data though was felt [finrandoba-chi]'s high on the audibility.
- I do not feel the Bonn luck feeling both speakers very much though there is somewhat swelling in the vicinity of FO of the unit.
- One understands ..listening.. [shite] compared with super-Swan few of amount of feeling of a low region. The expansion from an inside region to a super-high region has been postponed splendidly straight and the sound is how the honor student [finrandoba-chi] and MDF to ring. (No restive horse like super-Swan. )
