"I was looking for a low cost solution for some room re-verb!"
I was looking for a low cost solution for some room re-verb in my voice only studio and found these acoustic panels. At only one inch thick i new they would only be good for mid and high tones only, this was fine for a voice recording only studio ! I also did not want to glue them to my wall, like many others do, only to find out i destroyed my walls should a time come when i had to remove them. So, i decided to frame them along with a sound absorbing ceiling tile for backing and hang them around my studio like picture frames. Now i can move them anywhere i want to at any time and not destroy my walls. Over all, these acoustic panels worked very well for my application and work fantastic for a quality voice recording!
