All closed or semi-closed boxes (rack furniture) will resonate. So the more and wider the openings, the better. If you open only the back for ex, you'll likely make it better, but there will still be a resonance, albeit a lower one in freq. Also, it doesn't mean that without the back the furniture won't interact with the front wall anymore. It really is a case to case thing.When it comes to the "table top" reflections, well... nothing you can do about that really. Of course, angling the work surface is good, but if you angle too much then the back part of the work surface will create just as much trouble.I just try to keep it simple, small, and light. Avoid metal structures also, they can be nasty sources of parasite vibrations.Furniture is a bit like the floor effect. There isn't much you can do to kill it completely, but a few things you can do to tame it all nicely.Now, I'm not to worried when it comes to mastering furniture. An old large frame NEVE, now that spells *trouble*.
Hello Boggy,Thank you very much for your answer and your suggestions.I know that i can't get rid of reflections, especially as i'm not able to place my monitors so far away from the table. Nonetheless i need a table as the desk will be not only used to place my outboard, but also my production gear (keyboard, etc.). Therefore splitting the table won't work and is not an option for me.I know that having a table is a compromise between having an ergonomic setup and causing acoustical problems. Because of that, i want to build the table as small as possible and i'd like to know how steep i can angle 8RU-racks in a sterling style table without making the situation worse, given a close speaker situation and an 90 degrees angle at the back of the work surface/rack.
Speakers are Focal Twins on stands and the setup behind the table will look like this:
I'd love to move the speakers further back, but currently it isn't possible.
Hi Boggy,thanks again for the extensive input! Especially having a large LCD-TV in line with the speakers might be a good option.
Given the fact that i will build a desk, i'd love to hear your input on my original 8RU/20 degrees dilemma. I played around with some angles (15, 20, 25, 30) and checked the reflections from the tweeter. 20 degrees seem to be the best solution for me, as it already helps (a little) while having the speakers at a short distance, but even better, when i can go for a larger distance. At the same time the upper end of the rack/work surface is not too high to be in the way and the back of the racks doesn't become to dominant. Therefore i figured that 20 degrees might be the best solution for me..
If I forced to build that type of desk, I will possibly give a greater emphasis to better ergonomy and look... Good luck!
