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!"

  • Monitor 30s at home

    Driven by Bryston, and supported by (shh) B&W ASW750 subs.
    Sounds really quite natural!

    M30 + sub

    Very nice Paul, Do you use the Bryston crossover to adjust the subwoofer?

      Your setup

      Hi Paul:

      That's a very nice system. Who did the artwork above the one speaker? I really like it.

        Subs - crossing over and overlaps

        Yes. I used to use the built-in B&W crossover, then I bought a used Bryston crossover, and bypassed the internal one. The difference was amazing!
        the settings I have arrived on are a little bizarre though, mainly due to my room acoustic:
        Low Pass : 100Hz @ 12 dB/8ve ; High Pass : 75Hz @ 12 dB/8ve
        This gives a small lift in overall response in the overlap region which adds a little more "warmth" and makes cellos and string bass fuller.
        The B&W subs are extremely good, being clean, tight and at times earthmoving!

          Sub positioning

          Hi Paul
          I love the Harbeth Monitor 30 and own a pair my self along with the SHL5 and Monitor 40.1.

          Have you tried placing the subwoofers on the floor, just wondered if this gives you better bass response in room being connected with the floor and off the wall where you turn table is placed.
          Thanks Jason.
          Thanks Jason.

            sub positioning and flooring materials

            Yes Jason, I started out with the subs on the floor. The problem here is that the floors are wooden suspended floors (we live on the 1st floor of an old building) and they are not of the strongest construction! I found out early on that the floor resonated in sympathy with and in opposition to the driving force from the subs. The walls are quite heavily constructed with stone, brick and concrete and are very solid, The colouration in the bass from the subs exciting the flooring was dominating the whole sound. There is also a concrete pillar which is part of the structure of the house.
            The turntable is mounted on a steel shelf from Apollo hifi and is fastened with 6 expanding bolts into the concrete pillar. The subs are supported on two of the same shelves, but fastened into the walls. The subs weigh 32Kg each!

            Even with 300W per side into the M30s and 1Kw in each sub, I cannot now create acoustic feedback from the turntable which is only 18" /45cm from one of the subs. Vinyl sounds just as clean as CD in the bass, and seems to have greater detail in the midrange than CD even using the Bryston pre's built-in DAC, which in itself is a superb conveyer of detail, as long as that detail is in the recording in the first place.
            I have had to use a few bits of blu-tack here and there to suppress various rattles and rings in the room as everyone else has, I'm sure.

            With concrete flooring of course everything changes! I suppose bare earth floors would be the best in a listening room! (ducks the flack from the wife)
