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!"

  • C7Se3 + Skylan Stand => How to tame the bass

    Dear all

    Running a Naim system pairing a nice pair of C7se3 (on skylan Stand filled as required) i would like to know what can i do to tame the bass (Example in the last Kate Bush the bass are heavy and round...feel that bass as much as it should be)

    Tks for your advice

    Away from walls

    I'd first trying playing with the position of your speakers. If they near any walls, pull them out into the room a little more and see how that sounds. It's possible that, in their current position, your speakers are interacting with your room in such a way that the lower frequencies sound more pronounced.

      Tone controls solve room bass boost

      If there are no tone controls on the amp, I can't think of any way other than giving the speakers more room around them.

        Correct speaker placement .... and Kate Bush album

        Correct placement is vital with any speaker - get that right and you should have no trouble.

        You mention the latest Kate Bush album but does the fulsome bass occur on the majority of recordings or on some ?

          Try lightweight stands

          Hi , probably not happy combination of equipment, stands, cables/wires, speaker positioning, room size and acoustics :-(

          But I suggest, after you've tried replacing the speakers, you try some lightweight rigid wooden benches.
          I do use IKEA Oddvar tabourets myself with C7ES-3's, in Suisse they cost CHF17 a piece.

          Cheap enough to give it a go, I would say ;-)

            Before and after response using room correction

            Try plugging the port.

            And for the long term, see if you can improve the room's acoustics somehow. Or invest in a modern day equalizer. e.g. the upcoming anti-mode 2.0. I run the previous (mono) model with my home theater subwoofer and it's a fantastic tool.

            Here's the before and after response of said subwoofer with the antimode with just the press of a button and two minutes of waiting.*

            *The picture represents the basic frequency response of my subwoofer (which should be flat in response to a bit below 20hz according to spec) in my room, the calibration level is 80db accross the entire frequency line.
            The purple line represents the before situation, as you can see the subwoofer plays about 5db too strong most of the time with a peak of 10db a bit above 50hz, this is very audibile! Most people would just turn down the overall volume, this works well for the low bass, but the very low bass (-30hz) will be compromised, which kind of makes no sense, as it is a subwoofer.

            The blue line represents the response after calibration. As you can see it's now a lot flatter, which brings out the full potential of the subwoofer and makes it much easier to integrate.

              From what I have read here, it is almost impossible to do this for low frequencies in a domestic environment.

                Consider decay time and frequency response

                That is true for frequency response, but not so much for decay time. A short decay time is also important for a good sounding bass in-room.

                  Setup and previous bass experiences in my room

                  Tks All

                  The distance from back wall is about 65cm. The point is that i have a big element between speaker (Tv video,.....but nothing about audio ;-) ) and the distance from speakers is something like 40cm

                  As part of the WAF i have some limitation so have to move sloooooowly to avoid any home crisis ;-)


                  X (Speakers)

                  X X (List. Pos) Info : 1.5 speakers distance.

                  X (Speakers)


                  I know (based on some other speaker i had before) that my room (at least current position) is not bass friendly and it's not only the last Kate Bush ;-) (Beautiful album by the way). But as the C7s are really nice one i would like to extract the best from them .

                    Stand isolators?

                    Have you anything between the speaker and the stand besides the small rubbers that came with the stand?

                      Stands, and realism about room tuning

                      With all respect for opinions, but things that you put between a speaker and the stand aren't going to do anything for the frequency response in a room, unless it's a really bad stand that resonates at certain frequencies.

                      I've read another thread here that said something about special rubber feet to put under them with a very heavy kitty litter filled stand so that the speaker puts all of the energy in moving the air instead of itself. No offence, but I do believe that a person like designer A. Shaw who designed the speakers is capable enough of making sure his speakers can do all of that without any special accessories..

                      As I already suggested, I'm sure this problem is room related, and the solution lies in either treating the room, or adapting the speaker's response to match the room.

                      It's really that simple.

                        My experiments with stand decoupling

                        Hi there

                        I have some experiences with decoupling pads between stands and speakers. First of all I was very stubborn to use cheap stands, from ikea from lack table to odvar chairs in order to understand the speaker and design my own stands (on the future days) . And yes, the Harbeths sounds ok on this suports, but if you want to extract maximum from speakers you have to take care at few details...

                        So after a long and funny experiments, I made a pad composed from three different materials: a plastic from ikea also , a self adhesive cork from Auchan and a piece of corian from Dupont. I use 3 pads for every speaker with one in the front and two in the back. But these pads, are working also on the Sound Anchor stands (better than blue dots, wich come with the stands).

                        So my conclusion is the pads must have 3 layers with good contacts betwen they. And yes the bass is very clean.

                        I know, you believe that is not any science in this, but that experiments works for me.

                          Yep, i have the "Q-brick" (which provided with my Skylan)

                            Q-Bricks and big sonic difference

                            Try removing them so the speaker is on the little round rubber feet attached to the top of the stand. I'm not sure about the Q Bricks, but what I was using completely changed the sound in my room. I can't decipher differences in speaker cables, power cords and the like, but the difference when I removed the rubber pucks from under my speakers would be noticeable to anyone's ear.

                              What about spikes

                              What about spike ?
                              Today i'm using the screw with plastic head provided in the same pack as the spike (on the Skylan stand package). Never user the spike.

                              What can i espect ? Worth trying ?
