Where History Meets High Fidelity — The Sandwich 250 Loudspeaker
Introducing the Leak Sandwich 250 Loudspeaker—an embodiment of Leak's commitment to pushing the boundaries of audio excellence. As a beacon of innovation in the world of high-fidelity sound, the Sandwich 250 builds on a legacy that began in 1934, blending historical prowess with modern engineering to deliver an unmatched listening experience.
🏛️ A Rich Tapestry of Audio Evolution
The Sandwich 250 stands as a testament to decades of audio innovation, tracing its origins back to when Leak defined the very essence of high fidelity. With the original Leak Sandwich pioneering speaker design in 1961, the Sandwich 250 elevates this tradition to new heights. It encapsulates the essence of Leak's foundational innovations while embracing the advancements of the present day.
This speaker not only honors its heritage but also redefines it, offering a sound that resonates with both history and the future.
⚙️ Advanced Sandwich Driver Technology
Central to the Sandwich 250's superior sound is its advanced sandwich driver technology. The 11" low-frequency driver and 4.25" mid-range driver both employ innovative sandwich structure with stiff aluminum skin bonded to polymethacrylimide (PMI) foam core. This achieves a balance of rigidity and lightness that is rare in the audio world.
Wide-ranging frequency response with minimal distortion, ensuring every note and nuance is rendered with crystal-clear accuracy.
🎵 Premium 3-Way Design
The sophisticated 3-way vented-box, bass reflex design features dedicated drivers for each frequency range. The 11" bass driver delivers deep, powerful low frequencies, the 4.25" midrange driver ensures rich, detailed mid-tones, and the 1.2" coated textile dome tweeter provides pristine highs up to 26kHz.
Dual crossover frequencies at 470Hz & 3.1kHz ensure seamless integration between all three drivers for coherent, natural sound.
🏗️ Innovative Cabinet Design for Acoustic Precision
The cabinet is a masterpiece of acoustic and aesthetic design, reflecting over 60 years of evolution in speaker housing technology. Its construction—a sophisticated 'sandwich' of high-quality materials—ensures optimal strength and vibration damping. Features precise front-to-rear bracing and Leak's signature rear countersunk screws.
Real Wood Veneer Walnut finish with dual cabinet volumes (2.7L, 45.5L) engineered for exceptional acoustic performance and visual appeal.
