Electronic room correction will mess with voicing, so avoid that.
If the room is very small some absorption panels at 1st reflection might help but in typical rooms it'd probably make the sound less "awesome"... for lack of a better word. Diffusion is normally a positive. Very few rooms truly need absorption IMO. I did suggest absorbing the floor bounce and some bass but i would not overdo it. Dead rooms sound more resolving to the recording but not necessarily more musical/pleasant.
The first reflection points can be found by sitting down and having another person shift a mirror until you see the speaker through it. I'd want reflectors at first reflection points except in very tiny rooms. 4-5ft distance from speaker to wall is plenty but more never hurts.
I was asking since my receiver is a pioneer VSX-1019
I've never played with pioneer receivers but here are the measurements;http://www.hometheater.com/content/p...-labs-measures
It's roughly 130wpc @ 4 ohms, equivalent to a 65w @ 8 ohms amp. This will give you over 95db @ 10ft - pretty loud 90% of the time.
As far as power, a doubling of watts implies about 3db of gain. Which is pretty small but could maybe make a tiny difference if your amp is clipping, at least with some movie content. Try out the Crown I recommended earlier for what it's worth.. it's pretty inexpensive and offers some headroom (around 6-7db). However you will need to confirm if your 1019 has preamplifier outputs.
, would it help if I Bi-Amp them?
no. Advantages of bi-amping come with tricky speakers with multiple 4 ohm drivers in "parallel" with active crossovers. The PH use passive crossovers and no drivers operate in parallel thanks to the crossover and steep slopes. It's very elegant
Beyond that, based on the 5 channels driven measurements shown above, your receiver actually really struggles driving any more than 2 channels... so passive bi amping might br counter productive. It might be a good reason to add an amp to drive your mains as it will open the amps up for your surrounds.
