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!"

  • Screw Force vs. Performance

    Dear Alan,

    I currently owned M30 & M20 for over 5 year, and they did bring a lot of fun to me, really appreciated.
    Recently, I removed the front cover, and found out that several screws were rusted. (I thought this issue could be caused by the humid weather here.)
    Since my apartment is far away from local dealer, I am considering to replace them by myself.
    The question right now is that: do you have any torque/force requirement to tighten the screw (maybe refer to the production line specification) ?
    My friends always tell me that the force to the screw could affect the performance of the speaker. But I am thinking that unless the screw damage the speaker unit, otherwise, if the screw is carefully tighten, the speaker performance should be the same as before.
    Is that true?
    Thanks for your answer!

    BR,
    Mets

    Re: Screw Force vs. Performance

    I wouldn't be too concerned about the torque used for tightening those screws. Just make sure that they are reasonably hand tight or tightened with an electric screwdriver on a low-to-medium setting. There is no advantage whatever by over-tightening and you could strip the screw heads which looks ugly and may then shed small metal particles which could work their way into the magnet.

    So, just use common sense. It's rather like changing the wheel on your car: hand tight is much better than machine tight .... especially if you break down at night on an unlit road and just can't budge the machine tight wheel nuts!
