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!"

  • A speaker's life

    I own a pair of Harbeth c7, the original non SE , dated 1996. I wonder if their beautiful sound qualities will remain unaltered in time, or will they sound different in the next 10- 15 years or more? Is there an answer? Thank you

    :-) if you listen to it everyday or often, it will sound the same. :-)

    Speakers are physical and are made of things which deteriorate, the rubber surrounds on the woofers, the capacitors but truth to be honest, i have a pair of 18 year old Rogers and i cant hear a difference since i got them.

    Speakers can do with a bit of maintenance though and ill probably get shot here for saying this... if you are brave and you take out the rear binding posts and the bit with the crossover, wipe it with a white cloth after 15 years, that cloth will be soiled (oxidised material). if you plug the whole thing back together, your speakers will sound different i promise...almost like new, all things equal. but our ears would have changed after 15 years,

      Re: A speaker's life

      As a generalisation, speakers are reliable providing that they are treated with respect. The soft parts - as you say, rubber surround etc. - are the most vulnerable.

      Personally, I'd just leave them alone to age gracefully. If the speakers are in storage and not in use for months/years I'd turn them upside down to even out the pull of gravity on the voice coil. A nice wipe down with a barely wet cloth over the veneer every year or so should keep them looking fresh. You're right - our ears probably age more than the speakers, certainly over 15-20 years (sadly).

          P.S.

          Do not press, push or tap or knock the bass unit or tweeter cones

            Thank you Alan for your reply, actually I was a bit worried about some replacement of capacitors or other parts of the speakers, but as long as you don?t see the need of it, that?s all right with me!

              No problem. As a matter of policy, we try to use super long-life 'traditional' capacitors wherever we can even though we need to bank many of them together to achieve the total capacitance value we need. For example, on the P3ESR circuit board (see bottom still picture here) in the top-middle of the board there is a group of four very large (red-brown) dry-film capacitors, total value 40uF (4 x 10u) when one small 40uF 'modern' capacitor could have been used. We had the board area available so I decided to use the traditional polyesters. They should last virtually forever, certainly more than a human lifetime.

              When not constrained by cost or size, the designer has a free-hand to design for longevity.

                I am old compact 7 owner too. Many thanks for this thread. I own a pair of SHL5 too, the C7 sound still keep impressed me when ever I listen to it.
