"Exciting, Rousing, Dramatic" Speakers Combine Innovation and Timeless Heritage
Immerse yourself in the auditory excellence of the Leak Sandwich 150 Loudspeaker, a modern masterpiece rooted in a rich tapestry of audio innovation.
With a legacy that stretches back to 1934, Leak has been at the forefront of high-fidelity sound, revolutionizing the way we experience music. The Sandwich 150 is a testament to this enduring legacy, embodying the pinnacle of technological advancement while honoring the traditions of its illustrious past.
With its two-way vented-box, bass reflex design and 'Sandwich'-construction drivers and cabinet, the Sandwich 150 is a feast for the ears. It features an innovative 6.5" Aluminum-Foamcore Sandwich cone mid-bass driver, a 1.2" Coated Textile Dome Tweeter, and an advanced 'sandwich' MDF and composite board cabinet that contributes greatly to the exceptional sound quality.
"A Sensational Performance"
"In short then? One of the most exciting, rousing and dramatic speaker designs I’ve heard in some time, the Leak 150 speakers – for that price point – provide a sensational performance," raves Paul Rigby, theaudiophileman.com, June 6, 2024.
"In performance terms, the upper frequencies push the envelope to the max, they give you everything they’ve got. They don’t hold back. The 150s are triers, bless ‘em, they put so much effort into what they do… Bass was also exuberant, big, bold yet controlled and focused."
"Bang Up-to-Date" Design
"Leak's new Sandwich 150 and 250 are unashamedly inspired by the firm's classic speaker, which debuted in 1961. Bringing the, dare I say, 'crusty', design bang up-to-date Leak tells us that they've spread a healthy layer of state-of-the-art audio circuitry onto the latest iteration," observes stereonet.com, February 5, 2024.
"Excellent frequency and transient response," reports pursuitperfectsystem.com, June 5, 2024. "The treble unit includes a damped rear chamber to absorb the output from the back of the 30mm dome, isolating it from the rest of the loudspeaker and reducing its resonant frequency to below the crossover region. This allows bass, mid and high frequencies to be sewn seamlessly together."
"I've waited 63 years for a Sandwich – but Leak speakers are always worth the wait," notes Becky Scarrott, techradar.com, February, 2024.
The Journey Begins in 1951
The journey of the Leak Sandwich 150 begins in 1961, when the original Leak Sandwich set new benchmarks for speaker design. This tradition of excellence continues with the Sandwich 150, which integrates historical breakthroughs with contemporary engineering. The introduction of the world's first low distortion amplifier, the Leak Point One in 1945, and the subsequent development of the Leak sandwich cone diaphragm, are cornerstones of this legacy.
These innovations laid the groundwork for the Sandwich 150's exceptional sound quality, marrying the past with the present in a harmonious blend of form and function.
"They Will Have You Dancing Around the Room"
"The Leak 150 speakers for their price point provide a sensational performance," raves Paul Rigby in his May 19, 2024 review for his "The Audiophile Man" YouTube channel.
"These are speakers from a bolder time, a greater time, at least in hi-fi terms…. In performance terms, the upper frequencies push the envelope to the max."
"The upper frequencies from the 150s are detailed, lively, responsive, and agile. They excite, they wow, they will have you dancing around the room."
"Let's not forget the bass. For the 150s, it was strong without being boomy. It never overreached. It always remained in control. The bass had plenty of character, too. Low frequencies were anything but one dimensional. Tonal accuracy from the bass was excellent with plenty of tonal shades from the drums."
A Tasty Engineering Marvel: The Sandwich Driver
At the core of the Leak Sandwich 150's unparalleled sound reproduction is its innovative sandwich driver. A marvel of modern acoustic engineering, it features a stiff aluminum outer layer bonded to a lightweight, yet robust, polymethacrylimide (PMI) foam core.
This combination offers immense rigidity and lightness, allowing the Sandwich 150 to produce a remarkably smooth frequency response across a broad range. The result is sound reproduction that is free from mechanical break-up and distortion, ensuring that each note is delivered with unparalleled clarity and depth.
Cabinet Design: The Art of Acoustic Excellence
The Leak Sandwich 150's cabinet is not merely a container but also an integral component of its acoustic performance. Drawing on 60 years of technological evolution, the cabinet's design is a sophisticated 'sandwich' of MDF and composite board, meticulously layered for maximum strength and minimal resonance.
The cabinet is further enhanced with intelligent bracing and the iconic countersunk screw on the rear, a nod to the original's distinguished design. The cabinet's influence on the overall sound quality cannot be overstated. Its construction plays a crucial role in producing the deep, clear bass and rich, detailed sound that Leak is renowned for.
A Bridge Back to Hi-fi's Golden Age
The Leak Sandwich 150 Loudspeaker represents more than just a technological achievement. It is a bridge between the golden age of hi-fi and the limitless possibilities of the future. It stands as a monument to Leak's unwavering commitment to audio excellence, blending the historical innovations that shaped the industry with the latest advancements in sound engineering.
With the Leak Sandwich 150, you aren't just purchasing a speaker. You are owning a piece of history that's been re-engineered for the modern ear – without sacrificing the soul that made Leak a household name in high fidelity.
