After a lot of research and reviewing the info of this amazing forum my setup is going as fast as my wallet can handle. My current gear is:

Projector: Panasonic PT-AE3000U
Screen: Elite Cinetension 120"
DVD: Sony BDP-S350
TV: Samsung Retro-Projection (for gaming and normal TV)
Receiver: Onkyo NR906
Game console: Nintendo Wii
Harmony Universal Remote Control 880
Fronts: LSi 9
Center: LSiC
Rear: LSi 7
Back: Old sony speakers (need to upgrade)
Subs: Two PSW10 (need to upgrade maybe DIY)

The LSi9 arrive yesterday to replace the LSi7. My first impression is that the Onkyo can’t support the load of the speakers. When the LSi7 where on the front the room feels more fulfill:huh:. I’m thinking in helping the Onkyo with and amp to drive the LSi9 and the LSiC. I’m not an expert in this matter so I need some suggestion to achieve the best possible sound of the speakers. I will appreciate any help I can get.

I really doubt that an external amp will make any difference. The LSi7 and LSi9 are both 4 ohms, 88dB sensitivity, so they do not represent any real change.

If you need improvements, look to setup and room acoustics.

I agree with Kal, The 906 wont need any help driving either of those speakers. Once you do the Auddessey setup properly (read at least 5 positions) You should hear a great deal of improvement.

What are the dimensions of your room and how do you have your speakers placed in the room?

That bookshelf on the one side of the room will defiantly affect how the speakers will sound. The reflective points of that room are very high and will need some addressing for sure. do you have the speakers on stands or located in one of the shelves?

That's part of your problem. If you bring them out and put them on stands you will notice a big difference.

There are two things about the placement that are wrong
One, the angle is too far into the center of the room. You should not need more than a 5 to 10 degree angle given the layout of your room.
Two, the edge of the bookshelf being so close to the speaker will cause imaging issues, speakers need to be free of obstructions including the sides.

Thanks for your suggestions tonyvdb. I was very busy making the stands for the speakers to get it out of the shelves. Also the new angle of the speakers is 10 degrees. I sending some pics of the new setup. If your have another suggestion please let me now.

You really need some significant absorbent material on the room surfaces and bass traps. Looks like a pretty 'hard' room to me.
