I would like a sound system build for my Home PC that can reach up to 120dB.

Military jet aircraft take-off from aircraft carrier with afterburner at 50 ft (130 dB)

So you seriously want to put a Military jet in your living room to blow out every window in your house?

Standing right by a jack hammer is 110 db, every 3db increase requires a doubling of power/intensity, so 120db is 6x as intense as a jackhammer. Employers are required by law to provide hearing protection at that level.

Here is a loud PC speaker system that does not truly get to 120db: http://www.amazon.com/Logitech-THX-Certified-Digital-Surround-Speaker/dp/B0002WPSBC

No i just want it to be able to get to 120 decibels It will play at around 110 I have a system now that runs at 100 but its just not enough.

I have seen some stereo systems in cars that hit like 160 with subwoofers and thats what im going for it just didnt seem like 120 would be as loud as you guys are saying. I don't understand how the decibel system works all to well.

This video claims that his system is running at 120 Db https://www.youtube.com/watch?v=LIftWa0Al5I Seems ok ?

And if what you guys are telling me is true this is just insanity... https://www.youtube.com/watch?v=eIxDtvQnFug

The sound level meter in that video was not a calibrated one and may have been off by as much as 15-20db in the bass region so you can't use that as a guide to how loud that system actually plays.
Max volume is less important than quality of sound. Boomy loud bass doesn't give you the same sound that Steven Spielberg wants you to get. Being able to hear foley effects that are low in the mix and clear dialogue are more important. Get enough volume for your room and then go for better sound not more.

i just want my house to shake and it to sound good can that happen XD

You will be deaf a year after you get that system.

And trust me, you do not want to be deaf. I have 75% hearing loss. And that is bad enough.

I understand. Logitech z906 - you think this will be good enough?
