But then I think, during most surround mixes the sound is usually either fairly quiet or very loud and "furious" with so many sounds there is really no way to say that it does not sound perfectly timber matched.
It's honestly hard for me to invest in a speaker that can't quite manage 90Hz as I have a lot of powerful equipment in my theater room. But maybe crossing at 100Hz will sound great.
I can't wait to compare the P5V (slim) that I ordered to my existing Definitive Technology in wall UIW RSS II. The UIW RSS II sound terrible when compared directly to my P8 but honestly, for surround sound, they sound good. If I don't like the P5 compared to my P8 I will use the P5 for rear Atmos speakers and purchase P6 series for the remaining atmos and surround speakers.
We needed the P6V for our front side surrounds because we didn't have enough depth for the P5. The rear side surrounds are P5s. My MLP is in the front where I sit most the time. I have sat in the back, but haven't listened for a direct comparison between the P6V and P5. Having said that and trying to recall the differences, it does seem the front side surrounds are more "dynamic". For example, I use "Unbroken" beginning scene to demo often. When I sit in the front, those planes go through me more when they cross the room. I hadn't thought about it before, but yes, I think the P6V is more effective as a surround speaker. I will pay more attention to that as I swap to the rear row in the future.
I agree totally with your thoughts. The P6V should be a better, more dynamic speaker and a better match for the P8. Yet, much of the information on surround speakers doesn't require more than a P5. I think it really comes down to your budget. If the room wouldn't have gone over my budget so much, I was going to go ALL P6V/P6iW for the 10 surround speakers. My wife nixed me there. Nyal told me it wasn't necessary, but then again he told me to go with an AVR (to stay within my budget). I'm SO glad I went with separates! Nyal said putting money into acoustic treatments would be a better use of my money than to buy all P6/P6V/P6iW. I did replace a P5, but I think it was an anomaly. None of the other P5s have had issues. At least I got 3 x P8s and 2 x P6Vs!
I have seen several Procella company demo setups where they use only P5s for their surrounds.
My room isn't calibrated yet and the acoustic treatments aren't even built, much less installed. My room has many strengths. Like all rooms, it has its weaknesses as well. Right now I am only using my Yamaha to "process" until calibration when we will be using the Xilicas. Right now the weakness in the room is mid bass and lack of volume from the ceiling and rear speakers. I have all four ceiling speakers running hot at +9dB and the rears at +2dB. In the rear row, the rears are fine. In the front, they are not, but that is a weakness of a small theater, not the speaker. I do believe what I'm hearing is 3 x P8s in front of me and 2 x P6Vs to my sides and the P5s in the ceiling and rear are not keeping up as much. Obviously for some reasons as you mentioned (source material on those channels), but thinking about this more it may be the difference between the P8 + P6V and the P5.
Bottom line, if you have the money I would do the P6V/P6iW over the P5. Like Nyal said though, that money could be put to better use in other areas. Hope that was helpful and not to confusing.
