Let's do it like this. RF7ii have a sensitivity rating of 101db with 1 watt of power at 1 meter away.
So a single watt of power pushes 101db. Every 3db increase in sound will double the watts of power used
101db = 1 watt
104db = 2 watt
107db = 4 watt
111db = 8 watt
113db = 16 watt
117 db = 32 watt
121 db = 64 watt

Damn. Well I didn't win but I also didn't want to buy something sight unseen with the effort of reselling it on the off chance something didn't work properly. But I helped bump it up to $356 in the last minute before it sold
copy pasting from one of your other threads
Match the red and black from the speaker to the receiver (Sony box). Front Left and Front right. If you get one backwards it will still work but will sound a bit weird. The 3rd speaker would be called a Center and looks like that is listed as a Surround speaker on the Sony. This is entirely optional and may or may not work depending on the setting of the receiver. To get music it sounds like you'll have to hook up your phone or ipod. You'll need a 3.5mm (headphone jack) to RCA cable. Then plug that in to the back. Shouldn't matter much which one as long as you have that selected it'll work
If you plug it into Tape 2, you'll need to select Tape 2 on the receiver etc.
