LEAK Sandwich 250

The LEAK Sandwich 250 loudspeakers are the ultimate evolution of a classic British design that debuted in 1961. These 3-way standmount speakers combine a 1.2" (30mm) coated textile dome high-frequency driver, a 4.5" (108mm) midrange driver, and an 11" (280mm) low-frequency 'Sandwich' driver to deliver a remarkably smooth and accurate sound.

The Sandwich driver is the result of LEAK's innovative engineering, which uses a stiff aluminium skin bonded to a thick core of polymethacrylimide (PMI) foam. This gives the cone immense rigidity and lightness, enabling it to reproduce the signal applied to the voice coil without any mechanical break-up or distortion. The Sandwich driver also has a wide frequency range of 42Hz-26kHz, ensuring a balanced and detailed sound across the spectrum.

The coated textile dome tweeter is designed to provide a clear and natural high-frequency response, with minimal distortion and coloration. The tweeter has a ferrofluid-cooled voice coil and a neodymium magnet for high efficiency and low distortion. The tweeter also features a waveguide to improve the dispersion and integration with the Sandwich driver.

The midrange driver is also made of aluminium-foamcore sandwich cone technology, providing a smooth and natural transition from the bass to the treble. The midrange driver has a dedicated enclosure within the cabinet, isolating it from the low-frequency driver and enhancing its clarity and detail.

The LEAK Sandwich 250 loudspeakers have a sensitivity of 88.5 dB and a nominal impedance of 8 ohms, making them easy to drive with most amplifiers. They also have a sleek and elegant design, with a walnut veneer finish and a magnetic grille. The speakers come with rubber feet and optional spikes for optimal placement and stability.

The LEAK Sandwich 250 loudspeakers have a crossover frequency of 2.4kHz for the tweeter and 500Hz for the midrange, using high-quality components and a second-order Linkwitz-Riley filter. The crossover ensures a smooth transition between the drivers and a coherent soundstage. The speakers also have gold-plated binding posts for secure and reliable connections.

If you are looking for a pair of speakers that combine the vintage appeal of LEAK's heritage with the state-of-the-art performance of modern technology, the LEAK Sandwich 250 loudspeakers are the perfect choice for you. They offer a rich and detailed sound that will bring your music to life.

Sandwich 250 Stands (optional)

Many traditional stands would not allow for sufficient presentation of Leak Sandwich 250 loudspeaker. To address this consideration, the Sandwich 250 is complemented by a precision-measured plinth that positions the loudspeaker’s driver array at the optimum level and position. The result is a finely finished loudspeaker and matching stand combination of furniture-grade quality, that eliminates any compromise of the listening experience for the proud owner.
