He previewed the various combinations of enclosure and driver. Among them, he has fallen in love at first hearing with the dried ALTEC SOUND. He purchased a combination of MM-151ST and ALTEC CF204-8A. He loved a clear-cut ALTEC SOUND so much.   One day, he came to Hasehiro Audio and listened to the sound of SSC-impregnated MM speaker. He said,"My father is a carpenter, and he can japan. So I'll have my MM-151ST japanned. I am sure it will become a better sound, just like SSC." It is always said that japan makes good sound. The surface of japan ware is hard, and it is also impregnation material, like SSC. So, Hasehiro was looking forward to the sound. He said,"I'll bring my MM-151ST if it completes, and listen to the sound together."   Over two months have passed. Hasehiro received a call from him. He said,"It has finally been completed, but the sound went bad than before. I'll bring my MM-151ST this Saturday, and please tell me how to regain that sound.     Complete japanned MM-151ST published in Aug.2005: Hasehiro had heard from him that the color is not bright red, it's black. But the finish didn't have a bright polish. The front and the side baffle boards have austerely elegant color, perhaps because it had a low absorption rate. But the cutting surfaces of MDF, such as the front surface and the top board seemed to absorb enough japan. It seemed strange because it was like thick black writing fluid. He says it takes a high polish and he is going to polish up it at the end.   Hasehiro played percussive jazz CD. It's true that it is strange. ALTEC CF204-8A's cheerful dried sound is gone. It changed to a calming sound quality. Distinctive ALTEC SOUND has disappeared completely. ALTEC for jazz changed to ELCY Electric LC-12S for classical. Hasehiro never thought sound gets too soft by paint application. Original ALTEC CF204-8A played spine-tinglingly hi-hat cymbal, but it became soggy tone like put a damp cloth over the cymbal.     Soft-Sounding Altec Lansing   Hasehiro replaced CD to his favorite Kristina & Laura, and played "City of Dreams", he listen to it very often when he wants to check the sound of strings. He waited for the sound to come out with closed eyes. First, violoncello performance started. Feel good, that's fine! Hasehiro was chillaxing to the sound. Next, violin chases after violoncello ottavino. That's fine, too! Then, piano performance. It gave him goose bumps. Hasehiro could understand the sound quality a little if it is ALTEC CF404-8A, but it is CF204-8A. It can never produce like the sound.   In general, coating material for improvement of sound quality including SSC compound stops the resonance of the enclosure by the strength increase. So, he asked paint plant about japan later. According to the paint plant, japan permeates into it, and concretes remain soft. So it became soft sound. In case of SSC, it permeates into it, and harden like a stone.     Try to Get Altec Back   Mr.K said,"I'm a vocal pop listener, and never listen to classical music. I loved a clear-cut ALTEC SOUND, but japan completely changed the sound. How can I retrieve the ALTEC SOUND? I'll buy anything for this." Hasehiro replied,"This is really awesome! I think it would be a waster trying to get the sound back. Maybe everyone will have a great desire for the sound. I want this, too." But his feelings remain the same.   Hasehiro thought he has to plane the japan part, but I can't say it. Because his father finished the work with gloves and goggle spend two months. Hasehiro thought a few seconds, I'll buy this japanned MM-151ST from him and ask him to change it with a new MM-151ST. Then, Hasehiro recalled that SSC-impregnated CF204-8A is at hand. He had an intuitive feeling that this is it.   Hasehiro immediately replaced the natural ALTEC CF204-8A with the SSC-impregnated CF204-8A, and played Mr.K's CD. The cone of the SSC-impregnated CF204-8A glistens with SSC. It produces neither paper nor polypropylene sound when tapped a finger on the cone. As a result, Mr.K was greatly pleased with the sound. "I want to paint the cone with SSC soon when I get home." Mr.K rushed home after purchase the SSC compound for driver diaphragm.   About a week later, Hasehiro received a call from him. "I'm greatly pleased with the sound! It became congruent with the sound I heard at Hasehiro Audio after five coats." (This SSC compound for driver is weak prepared compared to it for enclosure.)   Anyway, tone color changes dramatically by the coating material of the enclosure. It's not an exaggeration to say that enclosure itself is diaphragm.   episode            Thank you for coming to the sound reproducing world.
