Can I use the same 5pcs speaker in the AV system? Is this perfect?

I think N803 is overkill for surround speaker. Probably it's more $ensible to get N803 for fronts and N805 for surround and use the money to upgrade other components or just buy more DVD/CD, or have you got a subwoofer. Tinhere is right about the center, and you should just buy HTM1 or HTM2.
Good luck.

I agree, it's going to be much more cost efficient to go with standmounts for the surrounds, and a specifically designed center.

That being said, I think Skywalker Ranch uses all B&W 801's in thier sound room. Must be nice!
