Well In order to have a good one, you need the sizes of the room. HxDxW. Then, the frecuencies with problems of stationary waves and how much spaces are you willing to sacrifice for it.
A lower hz scale means a larger wave, meaning, more space to trap the wave. Is pure and simple physic.
You can build one, but let me know your problems and I will teach you how.
Take care
