Back in the early days of hi-fi, around 1961, LEAK wasn't just making speakers—they were making history. Their original Sandwich speaker was a game-changer because it solved a big problem of the time: speaker cones that weren't stiff enough. You see, back then, the stiffness of the speaker cone was a make-or-break factor for sound quality. If the cone wasn't rigid enough, the sound got distorted, which was pretty common and a real buzzkill for music lovers.

So what LEAK did was kind of like what tech companies today do when they come up with a new smartphone or gadget—they found a clever workaround. They took expanded polystyrene, which is light and has good damping properties, and they sandwiched it between two aluminum sheets. This wasn't just for kicks—it was to give the cone the stiffness it lacked without adding too much weight. That way, the speaker could move back and forth really fast without bending out of shape. And just like that, the sound got a lot clearer, the bass felt right, and music had more punch to it.

Now, let's fast forward to our time. The new Sandwich 150 and 250 speakers from LEAK take that original stroke of genius and dial it up. They're leveraging all the advances we've made in materials and engineering to make something that's true to the spirit of the original but performs like a modern champ. We're talking about materials that didn't even exist back in the day, like aircraft-grade foam, which makes the new cones even stiffer and keeps the sound super crisp.

Why does this matter, you ask? Because music isn't just about noise; it's about feeling every strum, every beat, and every note exactly as it was intended. And that's what LEAK's new speakers aim to deliver, just like the original did all those years ago. It's about honoring the past not by staying stuck in it, but by building on it, improving it, and making sure the music always gets the respect it deserves.

New LEAK Sandwich Speakers A Legacy Reborn in Hi-Fi

LEAK, a brand with deep roots in the history of audio innovation, was established by Harold Joseph Leak in 1934 in London, England. Known for its high-quality audio components, LEAK carved out a reputation for affordability combined with high performance, a hallmark that defined the brand for decades.

Harold Leak, identifying himself as a 'Sound Engineer – Technician,' alongside Ted Ashley, who became Chief Engineer, propelled LEAK to the forefront of the home audio equipment market. Together, they led the company through an era of significant technological advancements in amplifiers, loudspeakers, pickups, and turntables.

The mid-20th century was a transformative period for LEAK, as the brand navigated the challenges of wartime disruption to focus on developing purposeful audio technology. Post-war, the emphasis shifted towards high-fidelity systems, marking LEAK's entry into an era of low-noise, high-performance products that gained international acclaim.

A pivotal moment came in 1945 with the introduction of the LEAK Type 15 amplifier, which featured innovative 'negative feedback' and 'push-pull' triode connected KT66 valves, achieving an impressive 15 watts output. This product laid the groundwork for the brand's reputation in high-fidelity sound reproduction.

The late 1940s and 1950s saw LEAK introducing groundbreaking products like the TL/12, which became a standard for high-fidelity sound, and embarking on marketing campaigns that directly compared live versus reproduced music, showcasing the superior quality of LEAK systems. These efforts culminated in LEAK's products being adopted by prestigious institutions like the BBC.

Innovation continued with the introduction of the LEAK Sandwich loudspeaker in 1961, a design that utilized a novel approach to reduce vibrations and resonance, leading to more dynamic audio reproduction. This period also saw the development of the LEAK Stereo 30, a transition to transistor amplifiers that offered a more accessible price point to a broader audience.

Despite its innovations and contributions to the audio industry, LEAK faced challenges from global competition and changing market dynamics, eventually leading to the brand's acquisition by the Rank Organization in 1969 and a gradual fade from the forefront of the audio market.

After years of dormancy, LEAK was revived by the IAG Group, bringing the brand back to the market with a focus on blending classic styling with modern audio technology, ensuring LEAK's legacy continues for new generations of audiophiles.
