Harbeth – P3ESR


The all-new RADIAL2™ coned Harbeth P3ESR is the ultimate mini monitor, the latest in a lineage that stretches back twenty years to the original Harbeth P3 and even further to the BBC’s pioneering LS3/5A.

A generation of home users and studio professionals has relied on these Harbeth minis to fill even the smallest room with a full, warm, natural sound. The P3ESR is the culmination of the designer’s four-years research into upgrading the Harbeth mini. From the new removable back panel for improved cabinet damping to the radically new bass unit yielding a wide smooth frequency response, every detail of these astonishing loudspeakers has been thoroughly honed and optimised. The objective has always been to create the genuine Harbeth sound in miniature: the P3ESR (R for RADIAL™) is that much closer to reality.

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 lifted from the larger Harbeths and is now at the heart of this new-generation P3ESR. Designed and made by Harbeth UK, the new RADIAL2™ equipped 110mm (5″) bass/midrange driver (a first for Harbeth) offers the hallmark clarity and naturalness of the larger Harbeths. 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 new variant of the P3 family’s well proven 19mm tweeter perfectly compliments the wholly new 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. Designed for ‘free-field’ use, the optimal bass-mid-top balance is achieved when the speakers are away from walls and on suitable stands at about tweeter-ear height. As with all Harbeths, the expensively engineered SuperGrille™ gives the loudspeaker an uninterrupted view into the room and is designed to remain fitted during listening.

Internally, the multi-function crossover divides the sonic spectrum between the drive units perfectly aligning the acoustic output into a seamless whole, exactly as you would hear standing at the microphone. This multi-functionality requires many expensive components chosen for their excellent acoustic, electrical and long life properties.  The necessarily complex P3 crossover topology is covered in ‘Tech Talk, Chapter 5′.

The Harbeth P3ESR is designed to give a lifetime of listening pleasure for all types of music wherever extreme clarity and naturalness is demanded.
