For over twenty years, we have worked towards sonic perfection in loudspeaker design. Today, our speakers are heralded by musicians and music lovers everywhere as among the finest in the world. Teresonic speakers are uniquely designed and individually handcrafted to provide unyielding dynamics, precise imaging, pinpoint accuracy and purest natural sound.

Teresonic speakers are designed as musical instruments. Their bodies are acoustically active like violins, cellos, pianos, acoustic basses… They are sculptured like musical instruments and built using traditional musical instruments making techniques and materials like fine Italian varnishes. Each Teresonic speaker is individually handcrafted to provide a lasting value – an instrument for generations.

Our customers say it best: “Having played in the orchestra behind performers like Issac Stern and Pinchas Zukerman I know what their violins sound like in real life. The [Teresonic] Integrums gave the most realistic reproduction I have heard from any speaker.” – DC, Portland, OR Read more customer comments…
