The P3ESR is a sealed box design, 2-way loudspeaker. This small, mini-monitor design is perhaps the best choice for music lovers who listen nearfield, at a desk, or in a smaller room. When used within it's limitations, the P3ESR creates an immersive, engaging listening experience that very few other speakers can. 

At the heart of the P3ESR's sound is Harbeth's proprietary RADIAL2™ technology. Taken from the larger Harbeth speakers and manufactured in-house, this technology is largely responsible for the magical qualities of their speakers. There is a reason Harbeth speakers have a cult like following, and this is a large part of it. Breathtaking transparency, realistic bass, amazing vocal reproduction and fantastic holographic imaging give the P3ESR a grand, captivating, and transparent sound. 

Easy to Drive

Not only is the P3ESR loudspeaker capable of being used in a wide range of listening environments, but it is optimized to present an easy electrical load to even low-powered amplifiers. 

We Recommend the P3ESR demanding listeners as a desktop, nearfield, or small space speaker.  Place it as close as foot from the wall behind it (minimum) and sit up to 8 feet away from them for maximum immersion. This is not a headbanger's speaker, but is capable of creating a captivating listening experience with nearly any genre of music at lower to moderate listening levels.

Classical, vocal centric and  acoustic music listened through the P3ESR are simply to die for.

If you need lower bass response or the ability to fill a larger room, try the Harbeth C7, Monitor 30.1, Super HL5 Plus, or Monitor 40.1.
