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!"

  • Acoustic treatment AND room correction DSP together?

    Has anyone tried a combination of acoustic room treatment and dsp processing with room correction capabilities?

    One advantage of this approach appears to be less critical positioning of loudspeakers within the listening room.

    Cheers,

    Room treatment and cosmetics

    Yup... here's the skinny on both.

    DSP correction is quite tricky because it only seems to "remedy" for one particular sweet-spot / listening position. Also, it is inherently dangerous as overzealous electronic correction can result in over-driving your amps and loudspeakers to try and "compensate" for null spots and suckouts (or worse yet, the DSP adding sustained high enery reverb to compensate for extreme notches in the perceived frequencies). Harbeths aren't exactly robust like Behringer or Cerwin-Vega! honkers. :P

    Plain old-fashioned mechanical room treatment is much more versatile in taming the overall room acoustics and works across a wider area of the listening room. They're also loads of fun to experiment with as you move bass-traps, diffusors, potted plants, thick drapes, Ikea bookshelves, and stuff etc etc all over the room and then have a re-listen (or re-measure, if you're technically analytical) each time.

    Only problem with room treatment is that they tend to have very poor Spousal-acceptance-factors, and can be very unsightly especially if you're deploying bass traps & broadband absorbers which are naturally big (it's a physics thing) and bulky items.

    As for using both those approaches at the same time, only you can decide which one you want to place more weightage on. It really depends on many factors such as what is your appetite for equipment & loudspeaker risk vs. how far you can push your luck installing huge ugly panels and remodeling the room and getting away with it.

      First mechanical then DSP

      Hi Chris, I used both mechanical and DSP treatments and love it. I would propose using mechanical treatments to the best you could in your listening environment, engaged in the DSP for the final "cleanup" for the frequency responses in your listening space.
      DSP would have both Focus and Global settings, one for the sit and position listening while another would be good for a all around listening.
