All the speakers in the EP80/500 set are very senstitive so you need only 1w of power to obtain 95db (loud) at 3 feet.
So, depending on how far you will seated and the size of your room, your power requirements are going to change drammatically (you need twice the power to gain 3db).

For anyone to answer this question, you would need to provide the following answers:
1) Size of room
2) Seating position
