Leak Sandwich 250 (2024)
A modern revival of a classic British loudspeaker, featuring aluminum-foamcore drivers in a precision-tuned cabinet
Overview
The Leak Sandwich 250 is a standmount loudspeaker introduced in 2024 as a revival of the original 1961 Leak Sandwich design. It is part of a new speaker line that includes the smaller two-way Sandwich 150. The Sandwich 250 features a three-way configuration with mirror-image left and right cabinets, combining modern acoustic engineering with the iconic design legacy of Leak.

The Sandwich 250 features precision-tuned cabinets with a mirror-image left and right pair layout, reflecting over 60 years of evolution in speaker housing technology.

The design is both an acoustic and aesthetic statement, staying true to Leak’s iconic speaker lineage.

The Sandwich 200 and 250 were historically highly regarded, and this new model continues that reputation with updated materials and engineering.
