Actual Home Theater Explosions

I just found the greatest way to improve the "earth rattling" sounds that are so impressive from explosions or rolling thunder in movies.

If you have the opportunity to get a second subwoofer for your system, put it IN AN ADJACENT ROOM with the volume way up and the crossover fairly low. The rumble it creates will make you feel like there are actually bombs going off in your house, which may or may not be good thing depending on the structural soundness of your house.

This will obviously not work for rooms that are completely acoustically isolated from other rooms, but for an average home it's amazing.

Note: This is not for casual listening uses, only for movies with serious LFE output. It would be best to turn the second-room subwoofer off for anything but large-scale movies.

Thats intersting Dusty, and I can completley see that giving another demension in the bass. So thunder for instense has a feeling of being outside.

This obviously won't work in all but it sounds like an intersting idea.

Interesting, but I can think of no reason in physics why it wouldn't produce the same effect if the second sub was in the same room. I think that the increase in effects was simply because you added a second sub to augment the first.

Maybe it makes the explosion longer if it is out of phase?

I don't think it's just about adding a second sub regardless of room location. If you want to rattle the vases in more than one room with two subwoofers in one room, you would have to turn those suckers way too far up. This way you spread the bass out over a larger area without overpowering the listening room.

It sounds like its creating a bigger space for the bass. The bass is expanded in another room creating a larger effect. Seems to make sense.
