The Leak Sandwich 150 stands as a testament to the enduring legacy of innovation that began in 1961, seamlessly blending historical advancements with modern technology to meet the highest standards of sound reproduction for audiophiles. It builds upon a tradition started with the original Leak Point One amplifier in 1945 and further advanced with the development of the Leak sandwich cone diaphragm, introducing an unprecedented level of rigidity and low distortion in sound reproduction. The construction technique utilizes an aluminium skin bonded to a PMI-based structural foam, similar to materials used in aerospace, ensuring minimal mechanical breakup and a smooth frequency response across a wide range. The cabinet, combining MDF and composite board in a meticulous 'sandwich' design, benefits from six decades of technological evolution, incorporating intelligent bracing and the hallmark rear countersunk screw. Aesthetically, the Leak Sandwich 150 boasts a classic design with a walnut real-wood veneer, aluminum trim, and a grille cloth chosen for its acoustic transparency, embodying the quintessential Leak styling. This model maintains a 2-way standmount configuration, featuring a 6.5” low-frequency 'Sandwich' driver and a 1.2” coated textile dome high-frequency driver, promising an audiophile-grade soundstage with meticulously arranged drivers for precise stereo imaging. Enhanced by a carefully developed crossover and a damped rear chamber for the high-frequency driver, the Leak Sandwich 150 delivers detail and harmonics that bridge the bass, mid, and high frequencies into a cohesive and detailed auditory experience.
