Amazing clarity and astonishing bass from a beautiful shoebox-sized cabinet - the RADIAL2™ Harbeth P3ESR is the ultimate mini monitor.
[The P3ESR is sold in some markets as the Monitor 20.1 Domestic.]

The P3ESR's exceptional all-round performance flows from the perfect integration of the cabinet, drivers and crossover. Harbeth's world-exclusive RADIAL2™ cone technology has been transferred from the Harbeth flagship to be at the heart of the P3ESR.

Designed and made by Harbeth UK, the RADIAL2™ 110mm (5") bass/midrange driver offers the hallmark clarity and naturalness of the larger Harbeths. Its concept stretches back to the BBC's pioneering LS3/5A - a loudspeaker capable of producing a big sound from a small souce.

Breathtaking transparency, real bass, and fantastic holographic imaging endow the P3ESR with grand, captivating, transparent sound presented in a conveniently small and beautiful cabinet. A 19mm tweeter perfectly complements the woofer and its open-weave protection keeps little fingers away but lets the fine musical details flow through.

Not only is the P3ESR capable of being used in a wide range of listening environments, but it is optimised to get the best from any amplifier, even smaller ones because the electrical load is so amplifier-friendly.

The design of the P3ESR's circuit board is available as a streaming video here.
