Im moving to a large trailer and 1 room will be a dedicated theater room. I been researching all day and came across Acoustic paneling and bass traps.. i have no idea if i need these or what exacly they do. I dont really have to make my room sound proff and keep the sounds from going out of the room. As you may know a trailer has thin wall panels that i will be replasing with sheet rock. Should i put insulation there wile im at it? will it make a sound diffrence? Do i need paneling and bass traps to make my HT sound better? please help im clue less. I just don't want to spend so much money just to find out i missed a step that would enhance the HT experiance.
