Or you can buy a big stero system of 100+w and add two more sound boxes to add extra 80+watts.

Then you can link your stereo system with your mega tv and select Aux..your stereo system will be connected with your tv...you can put your tv on mute if you like to...and increase the volume of your stereo to feel vibration under your feet..

I did it with my mega screen..working pretty well with extra bass, bursts and stereo...but you need a big room for this type of setup otherwise sound may hurt your ears.
