John Sayers' Recording Studio Design Forum Archive

Hi there.

The room I'm trying to improve is a concrete room with the dimensions: Length: 5.6m Width: 3.7m and Hight: 2.8 m.

I have come across 63 absorbers that where installed in a hi-fi store. I don't know exactly what material they are made of but the absorbers dimensions are Width: 540 mm Length: 800 mm and thickness: 20 mm. See the picture below.

The room will be used as a project studio so the studio and the control room is in the same room. The studio will mainly be used to record drums, guitars and vokals.

So how should i place the absorbers for the best results? Where should place the place where I mix and record? Should I place the monitors at the window, build some diffusors and go for a dead-end live-end room? See the picture below.

Your absorbers are made from semi-rigid glass fiber insulation. Absorbers made from this material have excellent properties, though The white, hard material that I see covering the face of one of the panels will reduce the panel's high end absorption. If I were you, I would probably dismantle each panel, put four of them together, and wrap them with fabric, thus making a new, better absorber from the raw mateials. 20 cm is very thin, adn such panels won't be of much use to you.

Thanks for your thoughts David!

The material that covers the panels is perforated all over and I don't want to ruin the panels so I'll leave them as they are. But I may put 3-4 of them together.

But my main concern is that I don't know where I should put them. Should they be evenly spread all over the room or mainly around the mixning area or the drums? Any idea on that?

1) Place panels on the walls where sound from your speakers will bounce off and come back to your ears or a microphone.

2) For best bass absorption, place panels across wall-meets-wall and wall-meets-ceiling intersections.

Also, if you edit your LARGE picture to remove all the unused space, it should almost meet the size requirements which are clearly posted in the very top link in each forum... Steve
