Optimum size for music room?


I hope this is not a silly question, so here goes.........
I may have the opportuneaty to build a room purely for music at the bottom of my yard. Is there an optimum size I should be aiming for, or is bigger better when it comes to room size? My speakers are Oris 150's and are 30" wide, 26" deep and 5' high approx. Also what about the height of the room?. Suggestions thoughts would be very much appreciated fellow goners'.

Thanks for all your input guys! good stuff! I will check out all the site/s mentioned. S'funny but the room I am listening to my speakers at present is 27'L X 13'W X 7'T. Being in a basement the room needs a lot of Improving to equalize it but as I maybe moving to a new place with no room in the new house (1000 sq ft), hence the 'new room question'.There is an amble space of 7000 sq ft of rear yard. WAF may come into play somewhere along the way.
Another question should the foundation be a concrete slab or would a suspended floor do the trick?
Many thanks again for all your input!
