HUG - here for all audio enthusiasts

At its inception ten years ago, the Harbeth User Group's ambition was to create a lasting knowledge archive. Knowledge is based on facts and observations. Knowledge is timeless, independent of the observer and can be replicated. However, we live in new world in which objective facts have become flexible, personal and debatable. HUG operates in that real world, and that has now been reflected in the structure of HUG.

HUG has two approaches to contributor's Posts. If you, like us, have a scientific mind and are curious about how the ear works, how it can lead us to make the right - and wrong - decisions, and about the technical ins and outs of audio equipment, how it's designed and what choices the designer makes, then the factual Science of Audio sub-forum area of HUG is your place. The objective methods of comparing audio equipment under controlled conditions has been thoroughly examined here on HUG and elsewhere and can be readily understood by non-experts and tried-out at home without deep technical knowledge.

Alternatively, if you just like chatting about audio and subjectivity rules for you, then the Subjective Soundings area is you. If upon examination we think that Posts are better suited to one sub-forum than than the other, they will be redirected during Moderation, which is applied throughout the site.

Questions and Posts about, for example, 'does amplifier A sounds better than amplifier B' or 'which speaker stands or cables are best' are suitable for the Subjective Soundings area. From Oct. 2016, Posts in the Subjective Soundings area will not be spell checked or adjusted for layout clarity. We regret that but we are unable to accept Posts that present what we consider to be free advertising for products that Harbeth does not make.

The Moderators' decision is final in all matters and Harbeth does not necessarily agree with the contents of any member contributions and has no control over external content.

That's it! Enjoy!

  • 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...
