I was just wondering if the m80 hp and the vp180 stranded will match in terms of sound since the m80 has 2 different drivers? This will be more for movies since I listened to 2 channel for music. I wonder if I should of gotten the Hp version instead?

You need to talk with Axiom about the sound pressure level you want to achieve with the VP180 and the frequency you are planning to cross it over to your sub.
If you are to believe the specs on the VP180 page, you should be able to drive it to around 115dB before compression takes place. Likely however, compression will start before that on the low end. If you are crossing over to a sub at around 40Hz or more, you will not need the HP in my opinion.

I believe that you are going to drive yourself crazy by second guessing all the time.
The difference in sound in the real world will be absolutely negligible, especially if you are using a decent sub or two. My VP160 is teamed up with M22s that don't have the 6.5" drivers that the VP160 does; however, they complement each other flawlessly.
While nice to have identical drivers in all of the speakers across the front, in the real world, timber matching is way over hyped IMO...

One last question, I read something at audioholic that you're not supposed to cross different frequency from each speakers to the sub because it may not sound right for the bass management and recommends you to keep all your speaker to 80hz.

And there lies the issue with most receivers in they use a general catch all for all speakers and not give a crossover for the sub. The thought of 80hz is they make believe that you cannot tell directionality at sounds below 80hz. BS. The number is also to allow for lower sounds to come from speakers that are not designed to make those sounds. If your receiver allows for you to get some overlap. Ie you can set your front M80 to cross over to the sub at 60hz, but have your surrounds and sub set to 80hz. That way the semi directional sound from 65-85hz can come from both the fronts and the sub at the same time and will feel more like it's coming from everywhere assuming the subs are not right beside the fronts.

Audyssey 'hears' both my VP160 & my M22s at 40 Hz in my room.
I set both crossovers at 60 Hz just to be contrarian to the herd I guess. Works for me...

With most newer receivers there's a speaker range and a subwoofer range setting. Having them different say 40 mixed with 80 shouldn't mismatch.
I have my subs at 80hz with my fronts large{40hz} and center Vp160 at 60hz and surrounds at 80hz no problem.
That 80hz all around is more of a THX recommendation, than anything else. The different channels in your receiver should cross them over without being to big a difference in channel separation.

That makes a lot of sense. So set the m80 to 60hz, surround and center to 80hz have the sub play from 80hz? Is 60hz the sweet spot for the m80 hp or can it go lower?

I chose the 60hz for two reasons. it's the point that the speaker starts to naturally decay off on it's ability to produce sound. Hopefully the receiver doesn't handle crossover points as a cliff that drops off to nothing, but as a point pleasantly decay down. Secondly as that is the point that the current requirements start to aggressively ramp up to drive the speaker for the lower hz sound.
Now if you are driving these speakers with a competent amp, then you can inch the crossover lower. The limiting factor for most is not the speaker but the amp that is driving the speaker to deliver clean power without clipping in a moving piece.

I have question about Room correction. If I wanted to EQ and flatten out bass bump at the lower frequency and leave the high frequency alone, what would the cut off frequency be at? 150hz?? My receiver default cut of is 5khz.
