Acousta 117, refined heritage and effortless musicality.
The Acousta 117 stands as Lowther's most enduring design, a folded-horn loudspeaker that has defined the art of single-driver reproduction for generations. Its carefully balanced geometry and handcrafted Baltic Birch cabinet deliver the immediacy, detail, and natural presence that only a Lowther can produce. Modern refinements in damping, adhesives, and finishing bring new stability and warmth to a legendary form. Finished in bespoke matched veneers and handmade in Great Britain, the 117 adapts gracefully to a wide range of spaces, pairing effortlessly with valve amplifiers for an experience that is as emotive as it is revealing. It remains the benchmark for pure, timeless sound.

Every Acousta 117 is handmade to order in our Northampton workshop. Each piece is built with care from start to finish by British craftsmen.
We use high-grade Baltic birch plywood for strength and tonal purity. Every panel is cut, shaped and joined by hand for perfect alignment.
You can choose from a range of real wood and specialist veneers. Each pair is book-matched to create a natural flow of grain that suits your space.
The drive units, including the PM7A Philharmonic, are assembled in our Norfolk atelier. Every part is crafted to the same standard as the world's finest instruments.
Each cone is hand-treated, air-dried and cured in natural sunlight. This gives every Lowther its unmistakably natural tone.
From wood to wire, every element is made to last for generations. A Lowther is not a product but an instrument that grows more beautiful with time.
Every cut, every joint, every finish is completed by hand. Our craftsmen bring decades of experience to each speaker, ensuring uncompromising quality.
Elegant and confident yet understated, the Acousta 117 brings the soul of live performance into the home. Its enduring form, refined craftsmanship, and adaptable nature make it equally at home in traditional or contemporary interiors. This is the speaker that defined the Lowther sound, open, immediate, and emotionally engaging, and continues to inspire audiophiles worldwide.
The PM6A (with Voigt's whizzer cone design) produces a wide dispersion and an airy, spacious soundstage. Combined with the alnico magnet, the Voigt folded spatial diaphragm reproduces music with a detailed yet balanced midrange and tight, well-controlled bass. The PM6A offers an authentic musical listening experience, perfectly showcasing jazz, classical and acoustic recordings with its clean, natural timbre and ability to resolve fine inner details. The end result is an engaging yet uncoloured presentation that gets out of the way so the music can shine through.
The Voigt horn plays a key role in extending the Lowther Acousta's frequency response down into the bass region, while maintaining a high standard of clarity, precision and blend with the rest of the frequency range. The horn flares at the front and aims to provide a natural, unfatiguing low frequency response that blends seamlessly and reinforces (rather than overwhelm) the midrange.
Whether you prefer the warm tones of a tube amplifier, the precision of a solid-state amp, or the efficiency of a class D amplifier, like all our loudspeakers, the Lowther Acousta will flawlessly integrate with your amplifier of choice. The Acousta will also house almost all 8" Lowther drive units, giving you the ultimate flexibility for your own personal musical taste.
