Theory Professional speakers are designed for projects where audio performance and architectural integration matter equally. From flagship retail environments to premium hospitality venues, these systems deliver powerful, consistent sound without compromising design intent.
Theory Professional speakers are engineered from the ground up for their intended application, rather than relying on off-the-shelf components, enabling a higher level of precision, performance and longevity.
Their full-range drivers feature specially treated carbon fibre diaphragms that minimise resonance and enhance durability, resulting in sound that is exceptionally clear, controlled and detailed. Across the range, even the most compact models utilise true compression tweeters with advanced polymer diaphragms, delivering high frequencies that are powerful and articulate without the harshness often associated with commercial speaker systems.
LSI works closely with interior designers, AV consultants and project teams to specify, supply and integrate Theory Professional speaker systems across Hong Kong, Macau and Asia Pacific.
