The way to tell the difference between the spinet and the console is to open the top, and look at the hammers (the felts that strike the strings) in relation to the back of the actual keys themselves. The Spinet Piano has a “drop action’, which means that the “action” is “dropped” below the level of the keys. A console action sits fully on top of the keys.
The Console Action (shown below)
Notice the keys fully extend under the action. The Hammers are well above the keys. This is called a “Direct Blow” action.
