If you're a DIY kinda person there's a whole series of U tube videos from a German acoustic engineer by the name Jesco. They are excellent. The videos on GIK are also informative. If you're not interested in learning how to fix the acoustic short coming in your room and build treatments yourself, there's a whole world of companies that will be glad to help at a cost, but hey it's part of the hobby for me. Good luck, it can be a rabbit hole if you get into it.
How to make small room sound bigger
Is It possible to make a relatively small room sound larger ? I have a 14 x 11ft with 8 ft ceiling. The room is completely empty, with vinyl floors with cement floor under. Looking into vicoustic sound treatments.
What would be the best approach with absorption vs diffusion and placement to attain a bigger sound space if at all possible ?
I wrote to vicoustics, but did not hear back.
