Hello, this is Yoshioka from Nihonbashi Store. The flu of this year seems to be spread terribly violence. Everyone, I hope you will not forget washing hands and gargle throat well. We may be reluctant to go out on the holiday as it becomes colder day by day. After all, it is an audio system!
It is 4311WXA and 4312A this week.
4311A was released in 1977 and 4312A was in 1986, and so the period was about 10 years. As you recognize it with a glance, it turned into general placement at 4312 from 4311 form that originally put a woofer in the upper part. It is the loud speaker that followed the change of a studio monitor, which is different from a general loud speaker.
4311WXA
A woofer is 2213 with professional specification, a squawker is LE25, a tweeter is LE25, things besides the tweeter are Alnico magnet. It has been changed into Ferrite one after 4311B.
4312A
The change parts after 4311 type are becoming inverted up and down, and a tweeter has become a hardware dome made by titanium from corn model.
A figure is similar, but a tone changed greatly. After all, it might be big because of the difference of a tweeter? There is roundness to 4311 in comparison with a modern loud speaker a little, and a feeling of thickness. Become 4312, a feature of a monitor considerably appears, and a feeling of details of its high level range was improved much, and the tone is with a feeling of speed.
