Pair up a music library with each product that will "Show off" the qualities of each Klipsch product.
Make it unquestionably obvious to even the most tone-def individuals that Klipsch = high quality audio. This could be as simple as a section on your website that will stream (with lots of buffering) or allow owners of Klipsch products to download a library of music that will make the particular Klipsch products they own shine. This would also be useful so that current owners would be able to show off there audio equipment with the best possible content (turning there friends and family into new customers). Effectively putting those kiosks from the sharper-image stores in every owners home.

Ultrasone has done a similar thing where they bundle a demo CD with every pair of headphones they sell. It could certainly help Klipsch to do the same and give out free test tracks with purchases in the highest audio quality possible (at least lossless files). That way, people will know how Klipsch products will sound like at their best. The test tracks could be on digital download, CD, or maybe even vinyl. The format should be whatever works best for the particular product.
