I tried many things in order to sound the last speaker with the highest sound. Consequently, No. 1 of sounding with the 36mm short board of maple was good.
I used the 16cm hole made before for the ellipse form with the round hole, without carrying out. My friend came to listen to it and said that a No. 1 natural sound had come. I understood now completely that it is good not to put into a box, but to sound with BAFFURU. I attached 2.5micro for the tweeter at first. Slightly heard noisy. Although it was regarded as 2.0 micro, this was also noisy just for a moment, And, finally I decided to the oil of 1.0 micro BITA Q.
A tweeter is before 3〜40-years corn type of RCA. I hared as the amount of bass had come out considerably compared with the ALTEC type box. More, when I attached a tweeter, I heard as low-range had come out. Although I do not understand why, even if it does how many times, I heard the low-range is different. How about you, readers, please try a tweeter on 0.5 micro or 1.0 micro?
