Bass traps in your studio – Improve the response in your control room

Bass traps treating the low-frequencies are the most important thing in our studio, they blurring the sound creating distortion and coloration. They concentrate on corners and there we must place our bass traps, wall-wall, wall-ceiling or floor-wall.

Placing bass traps in all corners will help to improve our bass problems, but the front wall and especially back wall have a strong bass buildup, so here it is a strategic place to put bass traps and improve low-frequency absorption even more.

DIY Bass Traps

You can build bass traps for your studio with rigid fiberglass or rock wool, approximate density 60k/m3, lengths of 60cm x 60cm or 60cm x 120cm are typical measures, a thickness of 15cm it´s needed for an effective low bass absorption.

“If you use thinner panels will only absorb mids and highs“

Standard panels of fiberglass or rock wool work very fine but now we have a new type of panel called ECOSE, they are more healthy and we can manipulate them without problems. Choose the one you prefer.You can buy panels of 5cm thickness and put them together but do not glue the pieces. A frame of wood or thin perforated metal can be built to make this traps, depends on your skill.To cover them use CARA fabric, it´s a special fabric for acoustics, let the sound travel and not allow fiber particles to escape. Please do not use your mom’s sheets.

Making your bass traps reflecting high frequencies

Maybe our studio has some absorbers with a great absorption on high frequencies (low RT60 on HF) or simply we want a natural or vivid sound not killing the ambient of the room.If we put our bass traps apart of absorbing low frequencies and mids they will absorb HF too, leaving a dead room. To avoid this we can make our bass traps reflective on high frequencies.Put a thin layer of plastic, kraft paper FRK or foil on the face side (use 1mm layer or less and glued lightly to the fiber).When a great amount of low-frequency absorption it´s needed, especially in small rooms, we will use super chunk or tri-corners traps and low frequency resonators.
