Product Overview

The LEAK Sandwich 150 is a modern reinterpretation of one of the most influential British loudspeakers ever made. The original Sandwich model pioneered bonded-cone technology, and the Sandwich 150 continues this tradition with contemporary materials and engineering refinements.

Featuring a three-way design in an elegant, vintage-inspired cabinet, the Sandwich 150 offers smooth integration across the frequency range, excellent tonal balance and a presentation that feels both classic and contemporary. It is designed for music enthusiasts who appreciate heritage craftsmanship and emotionally engaging sound.

Listening Experience

The Sandwich 150 delivers a warm, rich and articulate sonic performance. The midrange stands out for its natural tonality and expressiveness, allowing vocals and instruments to sound lifelike and textured. The soft-dome tweeter adds subtle sparkle and detail without harshness.

The updated Sandwich-style woofer provides deep, controlled bass with a satisfying sense of weight. The wide dispersion and cohesive integration of the drivers create a spacious, immersive soundstage well suited for a variety of musical genres.

Recommended Room Size

The LEAK Sandwich 150 performs exceptionally well in small to medium-sized rooms. Its balanced tuning allows flexible placement—on stands, consoles or bookshelves—while maintaining clarity and bass control.

Amplifier Pairing

The Sandwich 150 pairs best with amplifiers delivering **30 to 120 watts per channel**. Its impedance and sensitivity make it easy to drive, yet it benefits noticeably from amplifiers with good current capability and tonal refinement.

Both solid-state and tube amplifiers complement its warm, vintage-inspired sound signature, with classic British and modern integrated amplifiers offering excellent synergy.
