Klipsch Audio Technologies is one of the most successful consumer and professional speaker companies in America. It produces loudspeaker drivers and enclosures, as well as complete packages of loudspeakers for home audio, high fidelity sound systems, public address applications, and even personal computers.

Since its inception, Klipsch Speakers has promoted the use of horn-loaded speakers as part of its goal to produce speakers that can be driven by relatively low-powered amplifiers, and can accurately reproduce both soft and loud sounds. Some audiophiles decry horns as having a limited range of sound. Current Klipsch speaker designs, while still using horns for the tweeters, use a much more refined version which is considered less strident.

The flagship of the line remains the Klipschorn, a three-way, fully horn-loaded loudspeaker built since the founding of the company. There have been many improvements in the Klipschorn over the years, including a recent redesign and "revoicing" of the crossover network that results in a slightly "sweeter" sound, and smoother bass than in the past. Other Klipsch models with similar design principles are the La Scala and Belle Klipsch. These fully horn-loaded designs are claimed to deliver very realistic sound.

Current models are the Synergy line, it is sold by major mass-market retailers like Vanns.com. The Reference line tends to be carried by audio specialty stores and custom installers. The Klipschorn, La Scala II, Cornwall III, and Heresy III, as well as the limited-edition 60th Anniversary Klipschorn, comprise the Heritage line, which is available through select authorized Klipsch dealers, often by special order.

The company also manufactures products for multimedia purposes; its ProMedia line of computer speakers has been sold since 1999, and it produces iPod-marketed speakers like the iGroove and the iFi, a scaled down version of its home theater systems.
