Sorry for the pics quality.
I already DYIed a lil vocal booth but a "real one", This is kind of modular reflexion filter:
4 x 100 cm x 100 cm cheapest acustic foam = 10X4 + 10 (from germany) euros = 72 USD
8 x 200 cm x 50 cm wood panels = 8 x 8 euros = 93 USD
furnitures +/- = 16 + 2 + 30 (scratch) euros = 70 USD
so it's 235 USD and 2/3 hours of "work" taking your time.
Reflexion filter = 219 euros = 317 USD
What do you think? My DIYed booth is a dumb move or is it better than the reflexion filter?
Have not tried it yet. Jus finished. Never tried a reflexion filter either.
