Enjoy the most accessible Lowther drive units

The C Series is our most accessible range of drive units. Whilst we’re in pursuit of perfection, we also know that perfection comes at a price. So, we’ve made some adjustments to ensure that they’re more affordable for you. But we haven’t neglected the quality.

Compact quality

The C Series covers our smallest drive units, designed to fit into smaller speaker cabinets and cater to more compact rooms.

Affordable Lowther sound

Ferrite magnets make the C Series more affordable whilst still meeting our stringent quality standards. With ferrite magnets being the go-to-choice for many speaker manufacturers on the market, you can rest assured that they’re an excellent choice for a high-quality speaker.
