Leak Sandwich 250 Loudspeaker - Where History Meets High Fidelity

The Leak Sandwich 250 Loudspeaker is a striking fusion of Leak’s storied past and cutting-edge audio technology, designed to deliver an exceptional high-fidelity experience. Rooted in a legacy that began in 1934, this speaker builds on decades of innovation—starting with the original 1961 Leak Sandwich and the groundbreaking 1945 Leak Point One amplifier—to offer a modern masterpiece that honors its heritage while pushing the boundaries of sound quality.

Design and Heritage

A Legacy Reborn: The Sandwich 250 carries forward Leak’s pioneering spirit, integrating historical breakthroughs like the sandwich cone diaphragm with contemporary engineering. Its real wood veneer walnut finish and signature rear countersunk screws pay tribute to the classic Leak aesthetic.
Purposeful Evolution: This 3-way, bass-reflex speaker reflects over 60 years of design expertise, blending timeless style with advanced acoustics for today’s discerning listener.

Key Features and Performance

Sandwich Drivers: At the core of the Sandwich 250 are its innovative drivers: an 11" (280mm) aluminum-foamcore sandwich cone bass driver and a 4.25" (108mm) midrange driver, both featuring a stiff aluminum skin bonded to a lightweight polymethacrylimide (PMI) foam core. This construction ensures rigidity and low mass, delivering a wide 42Hz - 26kHz (±3dB) frequency response with minimal distortion. The 1.2" (30mm) coated textile dome tweeter completes the trio, providing crisp, detailed highs.
Acoustic Precision: With crossover points at 470Hz and 3.1kHz, the drivers work in harmony to produce deep bass (extending to 32Hz at -6dB), rich mid-tones, and clear treble, creating a balanced and immersive soundstage.
Cabinet Engineering: The vented-box cabinet, with volumes of 2.7L and 45.5L, is a ‘sandwich’ of high-quality materials reinforced with front-to-rear bracing. This design minimizes vibration and resonance, enhancing the speaker’s ability to deliver powerful, undistorted sound up to a peak SPL of 112dB.
Audio Specs: Boasting a sensitivity of 88.5dB (2.83V @ 1m), nominal impedance of 6Ω (8Ω compatible), and a minimum impedance of 4Ω, the Sandwich 250 pairs effortlessly with amplifiers from 25W to 250W, making it versatile for various setups.

Who It’s For

The Leak Sandwich 250 is crafted for audiophiles who crave a full-range listening experience. Its robust bass, detailed mids, and refined highs make it ideal for music lovers and home theater enthusiasts alike. With its wide amplifier compatibility, it fits seamlessly into both modest and high-end systems.

Why It Stands Out

This loudspeaker is a testament to Leak’s dedication to audio excellence. The sandwich driver technology ensures precise, distortion-free sound, while the innovative cabinet design—a nod to 60 years of evolution—enhances acoustic performance with deep, clear bass and a rich sound profile. It’s a rare blend of heritage and innovation, offering a visual and sonic presence that elevates any room.

The Leak Sandwich 250 isn’t just a speaker—it’s a piece of audio history reimagined, delivering clarity, depth, and emotion that connect the golden age of Hi-Fi to the possibilities of tomorrow.
