Laminar Spiral Enclosure (LSE™) Technology

The demands placed on subwoofers over the last years have increased substantially to the point where traditional design concepts are no longer valid. For Genelec, in order to achieve the absolute best performance possible, bold initiatives must be taken.

Drawing on years of acoustic research and knowledge, Genelec's engineering group accepted the challenges placed upon them in the beginning of the 21st Century. The totally unique, curvilinear shape of the LSE™ Series Active Subwoofer enclosure is the revolutionary patented result of their efforts.

All of the Genelec LSE™ series subwoofers feature this innovative Laminar Spiral Enclosure™ (LSE™) bass reflex cabinet. It provides excellent laminar flow characteristics with minimal turbulence noise and enables an optimal packing of a very long reflex tube into a small space.

The learnings from the LSE Technology are also utilized in the reflex port design of our aluminium enclosure products.

The spiral-shaped design yields an extremely rigid enclosure exterior while also forming the subwoofer's integral port. The fact that one is part of the other means that air flow in and out of the enclosure's interior through the port is totally unrestricted. This results in an extraordinarily accurate and responsive low-frequency system with measured second and third harmonic distortion levels typically better than 30 dB below the fundamental.

When combined with Genelec stereo and multichannel bass management active electronics, the LSE™ Series Subwoofers provide a low-frequency listening experience like no other. The result is a product range with impeccable technical performance: The Genelec LSE subwoofer range is unique, complete, functional, different from any other products on the market, and consistent.
