I have the ability to build a small listening room on a budget inside a larger space. Because the right and left walls will have to be accessible they will most likely be hung with heavy curtains although I could possibly hang sliding doors if necessary. Is there a standard formula for the application of sound reflecting/refracting/absorbing materials on the floor/ceiling/walls (front, back and side)? The room would be approximately 12 foot across by 18 foot deep with a 10 foot ceiling. The system would be a low watt tube amp with high efficiency speakers.

Thanks,
Scott
