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!"

Faulty woofer in Super HL-5

  • Faulty woofer in Super HL-5

    My Super HL-5's developed a fault recently. As far as I can tell, the moving coil in woofer is rubbing the magnet and the results in distortion. I changed amplification and cables and the fault remains. Has anyone had this problem?

    You can try to rotate the driver 180 degree.

      If the speakers are still under warranty, don't remove the driver, turn the whole speaker upsidedown.

      How old are they?

        Thanks, I tried that. Unfortunately distortion re-appears as soon as I raise the volume a bit.
        One has to wonder about the quality of the craftsmanship involved in making this speaker. It looks like this woofer was assembled badly, lots of glue used in a very untidy fashion. The woofer was also fitted badly and the screws didn't hold it in place in the cabinet which is why it may have been damaged in the first place. I am not impressed!

          The speaker is over two years old, unfortunately not under warranty )-:

            The best way to handle a matter like this is to contact the dealer from whom you purchased the speakers. Is there a reason that you didn't you register for the free extended warranty via the Harbeth web site? Generally the best way to motivate a supplier to help is to talk to them privately. I think you'll find your dealer helpful and sympathetic.

            Once we know the serial numbers and full history of your pair we can suggest the simplest/cheapest solution for you.

              I experienced that before on my previous SHL-5. I believe many Harbeth users have experienced that as well. For me, and as Keithwwk mentioned, i just rotated the main driver 180 degrees and all went well for me.

                After-car handling process

                The procedure for handling after-care is actually on the web site here and we take the matter very seriously. We have been dissecting the occasional returned drive unit under the video camera for some time now and archive those video recordings.

                With vented (ported) systems there is always the additional (small) possibility of dirt particles getting into the magnetic circuit.

                  Thanks - Harbeth UK have received back the woofer for investigation. As soon as we can get through the snow and over to the Harbeth R&D centre, we'll give it a full videod dissection.

                  As for the glue, there is nothing at all unusual about the postion or amount of glue used. The joints on the underside -- the critical ones that you don't see - - are rock solid. If there was less glue used the unit would fall apart!
