In either a wood stove or fireplace, the easiest and best fire is built by using a mixture of both softwoods–from trees such as pines and firs–and hardwoods, such as oak, eucalyptus, cedar and so on. Softwoods start burning easily, and the hardwoods provide for long burning and good "coaling" qualities. A bed of ashes underneath the grate produces steady heat and aids in igniting new fuel as it is added. The fire will continue burning if small amounts of wood are added at regular intervals. In fact, more efficient combustion results from burning small loads of wood with sufficient air than from burning large loads with minimal air.
When installing in-wall speakers, use a drywall saw to cut the hole. A utility knife will make the cleanest cuts in drywall, but a utility knife can be difficult to control by a non-expert. Electric rotary saws make cutting drywall physically easy, but they too can be difficult to control. A simple, inexpensive drywall saw (about $10 at your local hardware store) is the best bet for beginners. The speaker’s frame will cover up any rough edges.
