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!

  • Monitor 30 - Radial or Radial2 cone?

    I was just looking at the pages of both the domestic and professional version of the monitor 30, and the domestic version says it's build around the Radial cone technology, and the pro version states it's build around Radial2 cone technology.

    Is this correct?

    And also, is there a large difference between Radial and Radial2?

    Perhaps someone from Harbeth could give the answer?

      Apologies for the delay in replying. The 'RADIAL2' that you quote in your posting is in the introduction text of the M30 pro, not in the specification table.

      As we see it, the current position is this -

      Harbeth downloadable sales brochure
      shows (domestic, veneered) Monitor 30 as having a RADIAL cone.

      The Harbeth website shows the Monitor 30 (domestic) as having a cone of RADIAL technology here

      These are both correct. The M30 pro intro text is wrong and will be fixed.

      The difference is apparent if you inspect the woofer. The RADIAL2 woofer has a larger, 'softer' radius where the surround leads into the half roll. This subtly improves cone to surround to chassis damping at the top end of the woofer's working range.

        Keep going!

        Thank you for clearing that up. No apologies needed, how many owners of a premium manufacturing company would take the time to answer questions of single users this day anyway? It's very clear to me that you're a person who takes pride in his product, and puts as much effort as possible in making sure its users are equally satisfied.

        It's so nice browsing this forum and learning new things every week, e.g. how a seemingly simple question about boomy bass lead to you instantly providing us with an in depth article about room acoustics featuring multiple videos.

        Many thanks for all of that, I hope you can keep doing what you're doing for years and years to come!
