We are committed to deliver the finest music & movie systems, and rooms by merging the TriTone approach, with select partners and products that help bring our designs to life. We are strict on our systems' performance always, and take no short­cuts to achieve the best possible performance in every room & condition.

This has given birth to the need for room design services, which has expanded to themed theatres, private screening rooms, studio environment rooms, and control systems that make your fittings controlled in the palm of your hand. The most challenging obstacles have been to deliver high­performance systems in less­-than-­ideal acoustic environments. But through experience and developing our scientific approach, we have consistently delivered high-­performance systems in less­than­-ideal spaces. We want to deliver the best sound possible in any room. 

"The engagement of music involves achieving proper tone, timing, staging and imaging.
When the system sounds right, it is easy to immerse yourself in music engaging the mind, body, and soul. I've experienced this euphoria, and this must be shared."


We believe in a unique and customised consulting experience for each and every client. Every client listens differently. Every room is different. Every client wants to use his or her system differently. We consult to home owners, developers, interior designers, and business owners. We deliver bespoke solutions for AV, WIFI and Automation, tailored to you. Different cultures, one-­of-­a-­kind challenges.

Even in our curation of components, we prefer a customised approach, from the selection of finishing, the customisation of wattage in amplifiers, bespoke loudspeaker designs, music system solutions such as incorporating transducer technologies in large wall panels. In the field of automation, our graphic user interface is also a customized experience, down to the tone of the buttons.

"Where time is our most precious commodity, we aim to empower every full system we design in every room to deliver the best possible experiences in music, movies, and games. So our clients who become our friends, enjoy every second of it, every time."

“I believe in always creating value for the client, and in building relationships. Clients in tritone more often grow from clients to friends. As we first begin to look out for their best interest, they too, in turn look out for us as well. All in all, it does make our humble community a better place to be,

that’s what tritone is about - and I’m glad to share our approach”.
