Preparing your audio experience
Completing the top octave with precision and intent.
Every Lowther full-range instrument reaches remarkable heights on its own. Yet all eight-inch units experience a natural roll-off above ten kilohertz. Even when you cannot consciously hear those top harmonics, your brain responds to them. The result is a clearer image, stronger spatial cues and a greater sense of ease in the music.
The Lowther Super Tweeter is designed to continue exactly where the full range driver falls away. It adds nothing artificial. It simply restores the final part of the spectrum that completes the experience.
Configure the Super Tweeter with DX or PM magnet assemblies to suit your instrument.

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.
Made from the same materials and formed with the same approach as the cone and whizzer in our eight-inch instruments. The Super Tweeter avoids the usual disconnect of a bolt-on HF unit and instead sounds like an organic continuation of the driver itself.
Choose between DX or PM magnet assemblies to complement the energy and voicing of your system. Both options preserve transient speed while delivering effortless air and integration.
A compact enclosure with a broad dispersion waveguide allows the Super Tweeter to sit above or behind the main driver, maintaining subtle visual presence while expanding spatial realism.
In listening sessions at our Northampton studio—even with listeners whose hearing measured a roll-off above 10 kHz—the Super Tweeter delivered stronger imaging, more natural decay and a deeper sense of space. The ear may not hear the tone, yet the brain registers the cues.
Subtle in presence, profound in impact—the Super Tweeter restores spatial cues and harmonic information that transforms the listening experience.
“Once the Super Tweeter was switched off the music lost height. I could not hear the tone but I could feel the difference.”
“I thought my hearing had dropped above ten kilohertz. The Super Tweeter still improved the space around vocals and instruments.”
“It is not about hearing a higher note. It is about restoring the final cues that help you locate every sound in the room.”
“With the Super Tweeter engaged the stereo image locks in. Without it everything feels slightly flatter.”
“I did not expect it to matter at my age. It does.”
“The highs are subtle. The effect is not.”
