Hi everyone!
Ok, someone remember when Steve and I had a discussion about cinema's power needs (I put a photo of a destroyed Subwoofer).
Now, near my house, I bought a garage. There aren't houses on it and next to it. It is under a garden! The best place to reach 110dB...

So, I'm planning to build a great audio/video system within years. In the meantime I'm trying to understand what are my needs.
Steve (and Dolby!) told me that Dolby Digital maximum peak for each channel are:

LCR: 103dB
SR/SL: 100dB
SW: 113dB

I've calculated that witha 92dB/w/m speaker I need 236W for my room.
The problem is: if I double this power to have an extra headroom, I will drop in 400+ W power. And with these powers I'll need a professional system.
Many people (all?) are saying me that 230W are really too many watts for that room. But it is just math...
A friend of mine told me: 103dB is the maximum peak of the system. You should buy Hi-Fi 200W amplifiers that will be able to give you 400W for few moments during that 103dB peak.

Since we are talking of a lot of money, I don't want to buy a sound system that will be inadequate for my needs...

Would you pls give me your opinion? Steve, what do you think?
