Re: Сабвуфер для музыки / 31-03-2010 18:01
Вот нашел интересную статью по поводу настройки именно Rel Storm III. Может кому-нибудь покажется интересной:
dateline= писал(а):I was prepared for an hour of fuss and fidget, painstakingly taking bass measurements with the old Radio Shack meter and moving things around. Instead, David put a disc in player and instructed Al (the owner) and me to sit down and listen. He used the soundtrack to the movie Sneakers [Columbia CK 53146], but apparently anything with a repetitive low-bass signature will do. From there David simply directed us through the process.
He began with the Storm III in the corner with the most solid walls. He started the music and switched phase between 0 and 180 degrees and asked us to identify which was loudest. We settled at 0 degrees immediately.
Next he began the music again and moved the sub`s orientation from front to side wall and asked which was louder. Side wall was noticeably louder.
Now David began to pull the sub out from the corner diagonally, and asked us to tell him to stop when we noticed the sub lock in to the room. This step involves finding the \"axial node\" of the room, where the bass will be most strongly reinforced and create the greatest efficiency. At this point the sub would again become obviously louder and go deeper. It seemed as if David were hardly moving the unit, but sure enough the change was immediate and obvious. Not only did the bass increase in depth and volume, but also the soundstage just seemed to surround you when the right spot was reached. There was no coaching needed. It was that obvious.
The last step was to adjust the gain and crossover settings. With both dials at their lowest settings, David began to first bring up the gain, one click at a time. As soon as the sub became obvious and seemed to intrude upon the main speakers, David backed off one step. Finally it was time to set the crossover. The REL allows for both coarse (A-D) and fine (1-6) adjustments. When set correctly, the sound between the main speakers and sub will sound seamless, with a deeper and more dimensional soundstage, more precise imaging, and no loss in clarity. David told us it was rare to ever get beyond the A coarse setting, and he was right. Then it was just a matter of moving between the fine adjustments and confirming our selection with a few other recordings. What perhaps amazed me most was the difference in one fine adjustment of the crossover. I’m talking a difference of only 2Hz, yet the change was not subtle. We settled in at 23Hz.
The total time for setup on our first try was about ten minutes. The only tools used were located on the sides of our heads.
