Delivering a Truly Immersive, Soul-Stirring Music-Listening Experience to Proud Owners of Our Products

What the TAD Brand Stands for

Technical Audio Devices (TAD) was originally the name given to a project launched by Tokyo-based Pioneer Electronic Corporation (currently Pioneer Corporation) in 1975 to develop high-end speakers for professional use. The term embodies the belief held by the late Bart Locanthi, then a renowned professional audio engineer in the United States and a technical advisor to the project, that "genuine technology is true to the basics and that genuine technology places greater importance on sound quality than on technology for its own sake." This belief stresses the importance of an engineering approach backed by thorough theoretical evaluations and accurate testing and infuses an uncompromising pursuit of engineering perfection into the TAD brand and has been upheld for more than 40 years. For years to come, we will continue to create high-end audio products that are true to intentions of musicians and that deliver a truly immersive, soul-stirring music-listening experience to proud owners.

About TADL

Nearly 30 years after the first TAD-branded speakers were released, Technical Audio Devices Laboratories, Inc. (TADL) was spun off from Pioneer Corporation in 2007 as a company dedicated to developing and marketing a broader range of TAD-branded products, which include high-end amplifiers and disc players designed to bring the best out of TAD speakers. TADL’s mission is to inherit and advance the engineering prowess and assets accumulated by Pioneer in the high-end audio field over the years.

Corporate Philosophy

  1. We offer products that deliver a truly immersive, soul-stirring music-listening experience and that make their owners proud.

  2. We hand-assemble every one of our products using the finest technologies and with uncompromising attention to detail, no matter how technology evolves and no matter how people enjoy music changes over time.

  3. We continue to innovate by incorporating new materials and technologies into our product design while adhering to the basic engineering policy and industrial design concept we have refined over the years.

  4. We design our products that withstand the test of time and employ materials and technologies available only in Japan to enhance their artistic appeal.


"The Artistic Intent, Intant."

We at TADL make products that reproduce the genuine sound without adding any artificial coloration or omitting any of original musical nuances. This design philosophy, which has been embraced by every one of our engineers and incorporated into every TAD product since the founding of the brand, has been enthusiastically received by professional studio engineers around the world.

To design TAD speakers and audio components to reproduce the genuine sound, our engineers combine a legacy of our proprietary technologies with leading-edge materials, parts, and technologies. This approach enables TAD products to delivery a being-there experience to listeners. Listeners feel as if they were sitting in a front-row seat in a concert hall and enjoying music being played right in front of them, temporarily forgetting the existence of speakers and audio components in their room. We call this concept “the Artistic Intent, Intact.”
