Panel absorbers for my room?

Hi guuys, I have another question about my controlroom: Panel absorbers work well with my room size W. 12.25’ L. 18.30’ H. 8.50’?¿ Exist another best basstrap for the walls? My choice is in center of the side walls more or less, combined with the first reflection absorbers, it's a good place? I need anything for this place, somebody can help me? Thanks

Hola Xavi, y bienvenido! Bass traps work best when you place them in the corners of the room, not so well when they are just against the walls. The best bass trap is a "superchunk", which basically means making a large triangular shape stack of mineral wool or fiberglass in each corner of the room, stacked from floor to ceiling, and measuring about 80 cm across the diagonal front of the trap (facing the room): Cover it with acoustic cloth, to hide it. Panel traps are another possibility, but superchunks are very effective, and very easy to build. Superchunks are also broadband, whereas panel traps are usually more tuned to specic ranges of frequencies. First reflection absorbers are not bass traps: They are meant to absorb the highs, which are more directional and more easily reflected that lows. Search this forum for "superchunk" and "bass traps", and you should find a lot of information on how to build them. - Stuart -

Hoolaaa Soundman, muuuchas gracias! My question why I have the center of the side walls, aprox. 7 feets per side without treatment. Exist any basstrap that helps me in this place or it's better put only in the wall-ceiling corner?¿ Thanks

You could just do very deep absorption on those walls, say 8" or so of mineral wool or fiberglass. Or you could do a membrane trap, or even John's favorite: A slot resonator wall! You could tune that to specific frequencies, or just build it broadband. There are many options open to you! Use the "search" feature on this forum, to look for various key terms like "bass trap" "panel trap" "membrane trap" and "slot resonator": You'll find more stuff than you can imagine! - Stuart -
