Engineered with the flexibility to perform anywhere in a room, even behind furniture.
The Acousta Quarter Wave proves that high fidelity need not command attention to be exceptional. Its ingenious rear-horn design produces clean, articulate bass with signature Lowther clarity, even when positioned behind furniture or discreetly in a corner. Handmade in Great Britain and finished in bespoke veneers carefully matched to each living space, it is as beautiful as fine furniture yet unassuming in its presence.
At its heart lies the PM7A Philharmonic, renowned for warmth, speed and natural detail. Together, cabinet and instrument create a performance that rivals, and often surpasses, systems many times its size. Every pair carries a 10-year warranty and the assurance of a lifetime of listening pleasure.

Yes. Lowther full-range drive units have a genuine break-in period during which the diaphragm suspension relaxes and the sound opens up and smooths out. It is normal for a Quarter Wave to keep subtly improving well beyond 1,000 hours of playing - this is a characteristic of the design, not a fault.
