listening rooms

If you are going to use the 70 watt monos you will need to shrink your room to something like what I recommended previously. If you put up walls you want something sturdier than just sheet rock if you want to hear bass.

The "Master Handbook of Acoustics" by F Alton Everest has exactly the info you're looking for.

looked at cardis web site,i believe i will build the golden trapagon,2x6 walls with osb instead of sheetrock,any other suggestion,thanks robin
