HUG - here for all audio enthusiasts

Since its inception ten years ago, the Harbeth User Group's ambition has been to create a lasting knowledge archive. Knowledge is based on facts and observations. Knowledge is timeless. Knowledge is human independent and replicatable. However, we live in new world where thanks to social media, 'facts' have become flexible and personal. HUG operates in that real world.

HUG has two approaches to contributor's Posts. If you have, like us, 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 area of HUG is for you. The objective methods of comparing audio equipment under controlled conditions has been thoroughly examined here on HUG and elsewhere and can be easily understood and tried with negligible technical knowledge.

Alternatively, if you just like chatting about audio and subjectivity rules for you, then the Subjective Soundings sub-forum 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.

The Moderators' decision is final in all matters regarding what appears here. That said, very few Posts are rejected. HUG Moderation individually spell and layout checks Posts for clarity but due to the workload, Posts in the Subjective Soundings area, from Oct. 2016 will not be. 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.

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...
