Bass sensation like a loud car system in home?


I know this is a bit of a silly question but bear with me here:

What options are there for getting that feeling of a powerful subwoofer vibrating through your body in your home?  I know the easiest option would be to just put a capable subwoofer next to your seating and let it hit as hard as it can.  I'm also not trying to make all of my neighbors hate me so I'm looking for some creative solutions to pulling it off at reasonable residential volumes.

I'm thinking that some combination of tactile transducers in the couch and a subwoofer next to or also installed inside of the couch would get pretty close.  Being right under your body I wonder what kind of decibels would actually be required to get a bass massage going.  Without the sensation of the high volume bass it also might just seem silly and be a complete waste of time aside from watching movies.

Thoughts?

Yukispier, not a problem and you do not need to put vibrators under your seat either. Assuming a 16 X 30 foot room you will need 4 12" or larger subwoofers, 4 amplifier channels 1000 watts each and digital bass management. If you have the money and are serious about doing this I'd be happy to help.
mikelavigne - That's a very nice system, I'm envious. Why did you delete your post? I'd like to learn more, how do you know it's -3dB at 7Hz. and -6dB at 3Hz., was that correct?
I believe you guys kind of missed the point of the silly post.
