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.
Distinctive, superior engineered metalwork with nickel chrome finishing elevates these instruments to objects of both acoustic and visual beauty. High Grade EN1A Lead Free Steel, precision machined to exacting tolerances.
Each frame is precision-machined in our Norfolk workshop, with tolerances measured in microns. The perfect marriage of traditional craftsmanship and modern engineering ensures optimal magnetic flux control and structural integrity.
Our latest Sinfonia cone treatment delivers enhanced bass response while maintaining the legendary Lowther midrange clarity. Each cone is hand-treated and sun-cured, creating a diaphragm that combines rigidity with musical expression.
Real experiences from Philharmonic owners around the world
I finally understand what people mean by the 'Lowther sound'. The Philharmonics make music feel alive again.
I built the cabinets myself and when I dropped the Philharmonics in, wow!
Every friend who visits wants to know what they're hearing. They can't believe it's just one driver doing everything.
They're not just speakers, they're a piece of art. I still catch myself standing back just to look at them.
I've used countless systems over the years but these have ended my search.
Installing them myself made the first listen even more emotional.
I've owned systems five times the price, but none have ever made me feel closer to the music.
