HUG - here for all audio enthusiasts


"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!"

    "that speaker is darker"

    I don't know where to start this topic... this was a strange day for me...

    Shl5 is good speaker, with a kind of magic sound reproduction, but I always felt that something is missing till today, when my almost three years old daughter told me this: "That speaker is darker"... For few times I had an impression that the image is not very stable and I checked all the parts in my system ... from power cords to chanels of the amps, but after this episod with my daughter, I start to think that could be an Shl5 problem. So I removed the super grilles (even more a good sound but with the same problems) and examinate the loudspeaker. What I found you can see in the pictures from the attachment.

    I must say that my system has a "PRaT" and an very good resolution, so this difference between the speakers was obviously even for my wife after I rise this problem... I got the "right answer" : That speaker (the same) is darker!
    So I have a question:

    Are any references in the Master Log Book about this marks?
    Best regards.

      Hi Micron,

      I'm sorry to say that but I don't understand your problem by the picture you provide. I can figure that one woofer is darker by color but I'd need two picture of the same reference point to get an idea. Actually, I'm in a dark place regarding your problem. Please, give me some light.

        Micro-adjustements and a spec of dirt?

        Hi Sabastien
        Thanks for your care. The adjective "darker" was about sound and not about color of woofer or speaker...
        All that differences were very subtle and I tried to find physical differences between speakers... but the two pictures are from the same ( left ) woofer. And my question was if are any references in Master Log Book for this signs (the scratch and the red point), because this was the first time when I removed the grilles.
        Alan told me "is totally and utterly impossible that the small red item (wool?) can effect the sound" and to use a tweezers to pull it off. I tried but a quarter of the red point is still there because is sticked in a glue. I renounced to try anymore but I press gentle on the membrane to see if the red dot is moving or something... from interior of woofer...
        Anyway, I found another difference at the right speaker (the brightest one). When I looked thru the bass reflex port I saw a corner of the sponge, from the back wall, floating in the air about 3-4 cm. So I pushed back in the place.

        After all this micro-tunings. the stereo image became stable. So I fix the problem (for the moment, at least
        I cannot tell which was the problem... maybe was a sum of problems.

        Best regard
