Portable soundproof room demos at malls and tourist attractions
Create a portable soundproof room that you'd be able to transport and build at malls. Then set up the several systems within that soundproof room, that which people make enter and choose which systems they'd like to test. Gotta create that desire, and it's best done by making the potential consumers experience the beauty of Klipsch, not just seeing commercials and celebrities rocking them
Stores are always noisy, I agree.
