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!

  • Re: Harbeth SHL5 specific

    Thanks Alan,i understand that this year ,(or in near future), the new SHL5 model donīt will be in the market.

    I would like to see the Radial2 in the SHL5, and for example a only one binding post; anyway the SHL5 is fantastic.
    Alan, you can explain me the difference between the Radial cone and the Radial2.

    I going buy the Harbeth SHL5, and i have somes doubts.

    Best regards.

      There is no new model SHL5 so let's be clear about that!

      RADIAL2 (as used in the C7ES3 and M40.1) has a different surround to that used in the SHL5. The surround is an important part of the drive unit, for it not only allows the cone to move at low frequencies, but it also damps the higher frequencies. And it helps to keep the cone in position too. If you really want to have the RADIAL2 driver, then the C7ES3 is the model for you! It was designed using the same computer tools as the M40.1 and P3ESR. So those three models have some similarities. But you should listen, then decide for yourself.

      Incidentally, I could make the speaker have whatever sonic personality I wish using RADIAL or RADIAL2.

        O.K. Alan, i like more the SHL5.

        Sorry, but, i donīt understand your last paragraph, (my level english is low):

        "Incidentally, I could make the speaker have whatever sonic personality I wish using RADIAL or RADIAL2. "

          I believe Alan is referring to using his knowledge of how he implements all the ingredients of the speaker, including the crossover. There is nothing wrong with the RADIAL. It is different than the RADIAL2 but still very, very good. The SHL5 remains one of my favorite speakers.

          • HL5 - holistic design ...

            Yes John - thanks. RADIAL, RADIAL2 ..... these are small (but important) details.I can make an equal or bigger difference (if I want to) by manipulating some other part of the design - for example, the crossover. So, we have to consider the whole design not just be concerned about one aspect of the design.

            Example: we could change the tyres of a car but ir's very unlikely that we'd influence the performance of the entire vehicle. But if we were given, at the start of the design of the car, a certain type of tyre, we could optimise the car's overall performance for that tyre and no other.

              • Super Tweeter

                Dear Alan,
                I notice some current SHL5 used (1) half-flat-front frame-tweeter and some used (2) completely-flat-front-frame-tweeter. Base on what I had learnt here, the metal grille on the M40.1, 7ES3 and P3ESR tweeter had affected the dispersion of the high freq. I thought the two physically different super tweeter I mentioned above (1) and (2) shd at least have a little bit of effect on the high freq too. In fact, some owners who onwed shl5 with (1) upgrade to shl5 with (2) reported said the (2) give more open, extended airly high than the shl5 used (1).

                Interesting and I wonder is that true?

                • If AS would be willing to share, I would be most interested to read what instigated these changes to the tweeter? If not, I understand.

                  • I saw a SHL5 "Rendezvous" Special edition on ebay.

                    What is the difference btw that and the 30th Anniversay edition?

                    How many different Special Edition are there??

                    • In fact, there have been three different super tweeter versions during the life of the SHL5. Making a super tweeter is a very tricky technical challenge, and during our incoming QC we rejected about 40% of one type and threw them away. The supplier couldn't meet our quality standard - and worse, their commitment to resolving the issues was non-existent so we scrapped the tooling and re-tooled at another supplier. That's the expensive way to make a super tweeter but has restored the reject rate to just a few percent. Unless your friends are teenagers (or bats) I'd be astonished if they can hear any differences as the measured performance is very similar. I certainly can't hear any.

                      • Rendezvous edition and some personal thought...

                        If I not wrong, the Rendezvous ver was special made for TW. It was inspired by an extremely wonderfull Alan/Harbethian gathering in TW..Made with Tiger Ebony and OFC cabling inside and a gold plate pasted at back bottom panel there. This model was before 30th Anniversary.

                              Well, the use of studio grade ultra OFC internal wire would naturally confer better sonics overall...at least that's what i'd like to think as a customer.
