The Harbeth Monitor 30.3 is a high-performance loudspeaker designed for audiophiles seeking uncompromising sound quality.

With its advanced RADIAL4™ driver technology, the Monitor 30.3 offers an immersive listening experience that reproduces music as it was intended to be heard. 

All-new RADIAL4 Technology

At the heart of every loudspeaker is our drive mastery. Through pioneering work in the development of loudspeaker diaphragm material science, we have set a new benchmark with the acclaimed RADIAL4 cone technology: a true revolution in clarity and detail from a loudspeaker drive unit. 

Upgraded Crossover

Each speaker in the XD2 series incorporates a newly refined crossover design. The result is a speaker that excels in tonal accuracy and is more open and clear, immersing listeners in a more lifelike musical experience. 

The highest-quality veneers

We meticulously select only the finest, highest-quality veneers to craft our speakers, ensuring each piece not only performs to the highest of standards but also exudes timeless elegance. Each premium veneer is carefully sourced and meticulously inspected, reflecting our commitment to craftsmanship and attention to detail. The result is a speaker that not only delivers exceptional sound but also serves as a visually stunning addition to any listening space.

Since our formation in 1977, we have been on a quest to build the ultimate loudspeakers. We use the latest testing equipment to explore and reimagine every aspect of loudspeaker design. Furthermore, our expertly trained production technicians methodically test every part to achieve superlative quality.
