HUG - here for all audio enthusiasts


"This Harbeth User Group (HUG) is the Manufacturer's own managed forum dedicated to natural sound, realisable by controlling the confounding variables between tthe microphone and the listeners' ears.

For example, the design of and interaction between the hifi amplifier and its speaker load can and potentially will alter the sound balance of what you hear. To reproduce the sounds captured by the recording microphones, as Harbeth speakers are designed to do, you would naturally select system components (sources, electronics, cables and so on) that do not color the sound before it reaches the speakers.

Identifying components for their system neutrality should, logically, start with the interpretation and analysis of their technical, objective performance, as any and every deviation from a measurably flat frequency response at any point along the serial chain from microphone to ear is very likely to cause the total system to have an audible sonic personality. That includes the contribution of the listening room itself.

HUG specialises in making complex technical matters simple to understand, aiding the identification of audio components likely to maintain a faithful relationship between the recorded sound and the sound you hear. With our heritage of natural sound, HUG cannot be really be expected to guide in the selection, approval, endorsement or even discussion of equipment that is intend to introduce a significantly personalised sound to the audio signal chain. For that you should do your own research and above all, make the effort to visit an Authorised Dealer and listen to your music at your loudness on your loudspeakers through the various electronics offered there. There is no on-line substitute for that time investment in a dealer's showroom.

If you desire to intentionally tune your system sound to your personal taste, please consider carefully how much you should rely upon the subjective opinions of strangers. Their hearing acuity and taste will be different to yours, as will be their motives and budget, their listening distance, listening loudness and listening room treatment, not necessarily leading to appropriate equipment selection and listening satisfaction for you.

Alternatively, if faithfully reproducing the sound intended by the composer, score, conductor and musicians over your speakers is your audio dream, then understanding something of the issues likely to fulfill that objective is what this forum has been helping with since 2006. Welcome!"

  • Are UV rays damaging LS membranes?

    Hello, I have positioned my 40.1s (without grills) close to a window. For some hours per day sun is shining directly on the front of the speakers. Is this a problem for the membranes of the speakers? Do the UV rays damage the membranes? Thank you

    {Moderator's comment: yes I would expect the UV to attack the cones and surrounds. The recommended use (as per the User Guide) is grilles should remain fitted.}

    Do not let your speakers bake in the sun

    Definitely not a good idea in my experience, with any speaker.

    Personally, I would leave grilles on and draw the curtains or close the shutters. Don't leave them to be baked in the Sun.

      UV through window glass?

      not only the elements covered by the grilles, but also outer veneer doesn't like direct sunlight...

      But, is it really UV that ruins them? Because, almost 90% of the UV is already blocked by ordinary window glass...
