New LEAK Sandwich Speakers A Legacy Reborn in Hi-Fi

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.
