Leak Sandwich 150 Loudspeaker - A Fusion of Heritage and Innovation
The Leak Sandwich 150 Loudspeaker is a celebration of audio history and modern engineering, delivering high-fidelity sound that honors Leak’s pioneering legacy while embracing contemporary advancements. Rooted in a tradition that began in 1934, this speaker blends the iconic design principles of the original 1961 Leak Sandwich with cutting-edge technology, offering a listening experience that’s both timeless and forward-thinking.
Design and Legacy
-
Historical Foundations: Leak’s journey in audio innovation includes milestones like the 1945 Leak Point One, the world’s first low-distortion amplifier, and the original sandwich cone diaphragm from 1961. The Sandwich 150 builds on these achievements, reimagining them for today’s audiophiles.
-
Modern Craftsmanship: This 2-way, bass-reflex speaker combines a real walnut veneer finish with a sophisticated cabinet design, echoing the classic Leak aesthetic while integrating the latest acoustic engineering.
Key Features and Performance
-
Sandwich Driver: The heart of the Sandwich 150 is its 6.5" (170mm) aluminum-foamcore sandwich cone bass driver. Featuring a rigid aluminum outer layer bonded to a lightweight polymethacrylimide (PMI) foam core, this driver minimizes mechanical break-up and distortion, delivering a smooth frequency response from 44Hz to 26kHz (±3dB) with exceptional clarity and depth.
-
Treble Driver: Paired with a 1.2" (30mm) coated textile dome tweeter, the speaker achieves detailed highs, crossing over at 2.4kHz to ensure a seamless blend of frequencies.
-
Cabinet Construction: The 19.6L vented-box cabinet is a ‘sandwich’ of MDF and composite board, reinforced with strategic bracing to maximize strength and reduce resonance. This design enhances the speaker’s deep, clear bass (down to 38Hz at -6dB) and contributes to its rich, detailed soundstage.
-
Audio Specs: With a sensitivity of 86.5dB (2.83V @ 1m), nominal impedance of 6Ω (8Ω compatible), and a minimum impedance of 4Ω, the Sandwich 150 pairs well with amplifiers ranging from 25W to 150W, reaching a peak SPL of 106dB.

Who It’s For
The Leak Sandwich 150 is ideal for listeners who value both heritage and performance. Whether you’re enjoying vinyl, streaming high-res audio, or building a stereo setup, this speaker delivers a balanced, distortion-free sound that suits a variety of genres and sources. Its power flexibility makes it compatible with a wide range of amplifiers, from modest to high-end.
Why It Stands Out
The Sandwich 150 isn’t just a speaker—it’s a piece of audio history re-engineered for the modern ear. The sandwich driver technology ensures rigidity and lightness for precise sound, while the cabinet design—complete with a nod to the original’s countersunk rear screw—enhances acoustic purity. This is Leak’s commitment to excellence in action, blending 60 years of innovation with a design that looks as good as it sounds.
With the Leak Sandwich 150, you’re not just getting a loudspeaker; you’re investing in a legacy of high-fidelity audio, thoughtfully crafted to elevate your listening experience with every note.
