HUG - here for all audio enthusiasts

INTRODUCTION- PLEASE READ FIRST TO UNDERSTAND THIS FORUM!

"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!"

  • 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?
                    http://cgi.ebay.com/ws/eBayISAPI.dll...m=110532281772

                    How many different Special Edition are there??

                    Comment


                    • 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.
