Sandwich 250
Where history meets high fidelity.
The Sandwich 250 is a three-way bass-reflex standmount loudspeaker that reimagines Leak's original 1961 Sandwich design for the modern listener. An 11-inch aluminium-foam sandwich bass driver, a 4.25-inch sandwich midrange and a 1.2-inch coated textile dome tweeter work together across crossover points at 470 Hz and 3.1 kHz. The cabinet features multi-layer construction with front-to-rear bracing and a real walnut veneer finish. Sensitivity of 88.5 dB and a 6-ohm nominal impedance make the Sandwich 250 an easy partner for amplifiers from 25 to 250 watts.

Key Features
Sandwich Cone Technology
Aluminium skins bonded to a polymethacrylimide (PMI) foam core create a driver diaphragm that is simultaneously rigid and lightweight. This construction minimises breakup modes and delivers wide-bandwidth response with exceptionally low distortion.
Three-Way Crossover
Crossover points at 470 Hz and 3.1 kHz assign each driver a focused passband. The large bass driver handles the lowest three octaves, the midrange covers the critical vocal and instrument range, and the textile dome tweeter extends to 26 kHz.
Braced Cabinet
Multi-layer cabinet walls with internal front-to-rear bracing control panel resonances and minimise colouration. The result is a tight, controlled bass and a clean midrange free of cabinet-induced artefacts.
