Actually it needs 3 blocks to raise it to the right height.
Dispersion is limited, 1 pair of ears at 7', that's it.
Next, i need to play with baffle step to increase bass.
I found a graph showing the speaker's response climbs a bit.
And i plan on cutting a 12" hole, then mount the driver on another piece of wood for front baffle (3 layers total, unplanned), but driver placed right up against the top and not counter sunk.
It has potential, especially for lighter music and movies.
