Leak Sandwich 250 (2024)
A modern revival of a classic British loudspeaker, with aluminum-foamcore drivers in a precision-tuned cabinet
Overview
The Leak Sandwich 250 is a standmount loudspeaker introduced in 2024. It revives the original 1961 Leak Sandwich design. It belongs to a new speaker line that also includes the smaller two-way Sandwich 150. The 250 is a three-way design with mirror-image left and right cabinets. Both the midrange and bass drivers use aluminum-foamcore cones, which carry on the brand's sandwich cone technology - an aluminum/polystyrene/aluminum laminate known for rigidity and damping.

Design
The Sandwich 250 uses precision-tuned cabinets, laid out as a mirror-image left and right pair. That reflects over 60 years of evolution in speaker housing technology. The drivers have aluminum-foamcore cones, a modern take on the original sandwich cone. It is an aluminum/polystyrene/aluminum laminate that gives excellent rigidity and damping.
Context
The Leak Sandwich 250 builds on a history that began in 1934 and revives the 1961 Leak Sandwich design. It follows the Leak Sandwich 150 as part of a modern speaker line that reinterprets classic British hi-fi for contemporary listeners. The Sandwich 200 and 250 were historically highly regarded, and this new model uses updated materials and engineering.
