The time has come to gather resources. The office studios are becoming an unreliable back up and having a good room for fine tuning won’t always be at hand. The answer is room correction. (Thanks very much to the company for the unlimited use in the past years. Much obliged)
I’m always reluctant to invest time and money in things that might not work, and I’ve never been sure about this space. One thing I just recently found out was that the only thing I should be working toward is getting as much spec specific material into the room (especially corners) that I can. It works equally well if you just leave it in the bale it’s delivered in and stack it there.
Acoustic insulators like Rockwool and Earthsilk are fairly cheap. It’s the frames and nice fabrics they’re housed in that cost money.
My prices for getting only half the panels and corner traps I need hit a thousand quid fast. The price for the insulator itself is, so far, about £300 to do all the corners and the remaining walls. It won’t look nice, but when I need to make it into furniture, I will. Right now I need bass control.
These graphs were produced using Room EQ Wizard, a free software for precisely this.
That dip, from SBIR at the at 58Hz, is giving me massive drops all the up the spectrum. I need to absorb as much coming off the front and back walls as possible to weaken that phase cancellation.
After that I can start tweaking everything else. For now, there’s nothing that can be fixed until that is done.
It’s all from the shape and size of the room, (necessary) speaker placement, and listening position.
Back to it.
