LEAK Sandwich 150 Loudspeakers Walnut (pair)

The Leak Sandwich 150 comes in the format of a 2-way standmount loudspeaker with a combination of 6.5” (170mm) low-frequency ‘Sandwich’ driver and a 1.2” (30mm) coated textile dome high-frequency driver.

The Leak Sandwich 150 and 250 are the pinnacle of innovation that commenced in 1961 with the original Leak Sandwich.
Those technological advancements are implemented with the utmost regard for tradition, as well as the continual aspiration to forge sound reproduction equipment of the highest quality, accessible to every discerning audiophile.

Technology

The technology found within Leak audio devices presents science and innovation in abundance, yet the industrial design often draws favourable attention.

Just like the warmly received Leak Stereo 130 and 230 integrated amplifier models, the new Leak Sandwich 150 and 250 loudspeaker models maintain the understated, classic Leak styling. Finished in a sumptuous walnut, real-wood veneer, the cabinet is decorated with an aluminium trim insert matched and finished to the same exemplary standards of the driver trims and cone materials.

The decorative grille cloth is purpose chosen to match the classic Leak styling with a specification for maximum acoustic transparency.

A keen eye will also notice that the new Leak Sandwich 150 and 250 are supplied in perfectly matched pairs with a ‘handed’ array presentation.

Industrial Design

Much more than continued industrial design traits, the meticulous placement of each driver is considered to the nth degree, thus enabling a projection of a truly precise stereo soundstage.
With the Leak Sandwich 150 and 250, the high-frequency driver has been developed, incorporating a rear chamber damped to absorb the output from the back of the dome.

This innovation not only isolates the HF unit from the rest of the loudspeaker, it has the added benefit of reducing the resonant frequency of the treble unit.

Taking the resonant frequency below the crossover region means the audible spectrum of the bass, mid and high frequencies can be sewn together with an added dimension of detail and harmonics, eliminating the requirement to harshly adjust the definition of the high-frequencies.

And that very sewing is conducted by a crossover of the highest order, developed over thousands of hours of listening, not just simulation as is the tendency in modern loudspeaker design.
