Every Lowther drive unit is the result of meticulous hand assembly, decades of refinement, and an unwavering commitment to sonic excellence.
At the heart of every Lowther lies a voice coil wound entirely by hand, to tolerances measured in microns. Copper, silver, or gold alloy wire is layered under exact tension to achieve balance beyond the reach of machines.
Every component is brought together by craftsmen whose experience spans decades. Their skill and intuition, the ability to feel perfect alignment within a human hair's breadth, ensure flawless centring and effortless movement.
Our paper cones are individually brushed with proprietary treatments, then cured slowly in natural sunlight. This organic process creates a surface both rigid and alive, capturing musical textures with breathtaking speed and delicacy.
Every drive unit undergoes exhaustive acoustic and mechanical testing. From precise frequency analysis to the tactile inspection of cone travel, nothing leaves our bench until it meets the sonic ideal that defines Lowther.
Our metalwork is forged from premium lead-free steels. This geometry channels magnetic flux with maximum efficiency, forming the silent architecture beneath the Lowther signature: lightning-fast response and effortless dynamics.
From traditional Alnico to modern Neodymium and the rare Permendur and Magmax of our Grand Opera instruments, each magnet composition shapes character and tone.
The Sinfonia Collection introduces a newly developed premium diaphragm that represents a significant advancement in cone technology. Enhanced structural integrity and refined resonance characteristics deliver noticeable improvements in clarity and resolution across the entire frequency spectrum.
Building on nine decades of expertise, the Sinfonia features an evolved paper treatment process that enhances transient response and tonal accuracy. This proprietary refinement maintains the warmth and musicality of traditional Lowther sound while unveiling new layers of detail.
Every Sinfonia drive unit benefits from the latest advances in precision manufacturing while maintaining our commitment to hand assembly. The result is exceptional consistency and performance that honours our heritage while embracing innovation.
