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!"

  • Sub Woofers

    This is not particularly a Harbeth question, Alan, but I would value your technical opinions, as I am sure others would.

    Having moved my main system to a house in Cyprus I have for the present cobbled together something for a UK flat I will occupy a few moths a year.

    I have a Quad 77 CD Player and Tuner with the 77 Integrated Amp driving an old pair of Goodman's Maxim IIs. Not great. I add in a KEF PSW 2500 set very discretely and immediately the stereo image and general clarity seems to improve and everything is a good deal less strained.

    Am I fooling myself that I hear improvements that are more than more bass?

    What's going on?

    When using a much more modern a higher quality speaker like the P3 does a good, well adjusted sub make contributions to system clarity beyond raw bass extension?

    Most of the energy in the human voice and obviously music too is concentrated in the middle frequencies. It's hard to imagine that improving/adjusting either end of the spectrum (the lowest or the highest frequencies) will have any real effect on the middle frequencies. As stated again recently, the cone material defines the quality of reproduction. we can't recall the Goodman Maxim 11 --- are they from the 70s? --- perhaps with paper cones? That'll be the quality limitation no matter how your ear is pulled to the low frequencies with your sub. Our guess would be that if you turn down the contribution of the sub you will return your attention to the middle/top frequencies.

      Subs and removing the load from the satellites?

      Could it be that the addition of the sub removes some of the load from the Maxims and allows them to "breathe" more? Does the KEF have a crossover which separates out the "highs"? If the sub is wired via the tape loop this could well be the case.

        KEF sub

        The KEF Sub is driven from the Pre-out of a Quad 77 Integrated Amp. The Maxim IIs are still being driven across the full range, but, of course, they naturally roll off in the bass.

        An old thread, but note the speakers in question are not Maxim Elevens ( I don't think they were ever made) but Maxim Twos. And yes, the bass-mid unit has a paper cone.
