INTRODUCTION - PLEASE READ FIRST TO UNDERSTAND THIS FORUM!

"This Harbeth User Group (HUG) is the Manufacturer's own managed forum dedicated to natural sound from microphone to ear, achievable by recognising and controlling the numerous confounding variables that exist along the audio chain. The Harbeth designer's objective is to make loudspeakers that contribute little of themselves to the music passing through them.

Identifying system components for their sonic neutrality should logically proceed from the interpretation and analysis of their technical, objective performance. Deviations from a flat frequency response at any point along the signal chain from microphone to ear is likely to give an audible sonic personality to the system at your ear; this includes the significant contribution of the listening room itself. To accurately reproduce the recorded sound as Harbeth speakers are designed to do, you would be best advised to select system components (sources, electronics, cables and so on) that do not color the sound before it reaches the speakers.

For example, the design of and interaction between the hifi amplifier and its speaker load can and will alter the sound balance of what you hear. This may or may not be what you wish to achieve, but any deviation from a flat response is a step away from a truly neutral system. HUG has extensively discussed amplifiers and the methods for seeking the most objectively neutral among a plethora of product choices.

HUG specialises in making complex technical matters simple to understand, getting at the repeatable facts in a post-truth environment where objectivity is increasingly ridiculed. With our heritage of natural sound and pragmatic design, HUG is not the best place to discuss non-Harbeth audio components selected, knowingly or not, to introduce a significantly personalised system sound. 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 offerings there. There is really no on-line substitute for time invested in a dealer's showroom because 'tuning' your system to taste is such a highly personal matter. Our overall objective here is to empower readers to make the factually best procurement decisions in the interests of lifelike music at home.

Please consider carefully how much you should rely upon and be influenced by 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, loudness and room treatment, not necessarily leading to appropriate equipment selection and listening satisfaction for you. Always keep in mind that without basic test equipment, subjective opinions will reign unchallenged. With test equipment, universal facts and truths are exposed.

If some of the science behind faithfully reproducing the sound intended by the composer, score, conductor and musicians over Harbeth speakers is your thing, this forum has been helping with that since 2006. If you just want to share your opinions and photos with others then the unrelated Harbeth Speakers Facebook page http://bit.ly/2FEgoAy may be for you. Either way, welcome to the world of Harbeth!"

      your hammer may break the warranty of the grille only, not speakers I hope :-)

      Did you leave the grille in extreme weather conditions?
      I remember there were another post saying that he couldn't take the grille out easily, though. What I understand is it fits tightly, so may be we shouldn't be too polite while taking it off and putting it back.
      Is it possible to use it upside down? Is the label fixed?

        • Slide-on fit of M40 grille

          Could we know please why you removed the grilles? As you will know from here and the User Guide all Harbeths are designed to be used with the grilles fitted. Not only is that what the designer intended but it prevents the grilles steel-frame from being bent. Clearly the speakers were supplied with the grilles fitted. The M40/M40.1 grille has always been an easy slide-fit so we can be sure that they slid on nicely at the time of manufacture.

          • Grille off/on - no effect?

            yes, of course could you know!
            and i know the recommendation well but i also read that it is doesnŽt effect sound, with or without. so i decided what i (and my wife) thought looks best. at the time we bought them it was better without grilles. recently we changed furniture etc and find the looks better with grilles now. meanwhile they where stored in our (dry) basement.

            {Moderator's comment: no we never said 'couldn't effect sound' because that is untrue! Any object/cloth placed in front of a drive unit does and must and will effect sound! Because the sound must pass through the cloth, so there will be some loss. But the designer compensated for that as best he could.}

            • Check the diagonal measurements!

              Hi Delgesu,
              The Grille is a bit flexible in the diagonal direction and perhaps measure this diagonal distance to see if both diagonals are equal. If you start the Grille at bottom groove and work up, you can push the frame a bit left or right as you reach the top of the cabinet. It is best to not push the Grille all the way into the groove when starting at bottom as this may appear to show extra length at the top.

              (I would check with your dealer first to see if he can help with a replacement if the above does not help, as shipping a grille on it's own can get damaged also in transport).

              Cheers,
              Noel.

              • Controlled grille fit

                Think the grilles are bowed inside slightly and intentionally (in the middle lengthwise) and works on the principle of friction and grip* to hold it tightly in place. The 4 corners of the grille should be square with your speaker corners, and unless they have been (unlikely) bent at just these spots, tender guidance will put it back.

                • hi noel,

                    • Wood swelling in the tropics

                      Delgesu,

                      The grilles on my 40.1 don't fit as well as when they first arrived. They used to sit flush on all sides but not so these days. I listen with the grilles on the speakers.

                      I had a problem with my last set of speakers, the Sonus Faber Cremona. If you are familiar with these speakers they have elasticated string "grilles" which fit into holes, top and bottom of the speaker. I removed them and a year later couldnt put them back in. The wood had expanded. I live in the tropics.

                      {Moderator's comment: the Harbeth grille frame around which the cloth is glued, is a welded, powder-coated steel band. It cannot of itself change shape or size. It can be accidentally bent though if removed: on reason we mention that our speakers are designed to be used with the grilles fitted. The M40/40.1 has always been the easiest grille to fit due to generous tolerances in design and manufacture.}

                        I listen with the grilles on but remove them from time to time when I dust down the speakers. The tolerances are adequate to make an easy job of removing the grilles and therefore unlikely I could have bent them out of shape when I removed them. I take all care when they are off the speakers as well. However fact remains the don't sit as flush as they used to.

                        • Left and right?

                          Hi Kathy, Have you checked to make sure you have the grill cloths positioned for the corresponding Monitor 40.1 left & right hand speakers.
                          Sounds obvious but the Harbeth Logo should be located on the left hand side top for the left M40.1 speaker and on the right hand side top for the right M40.1 speaker.
                          Just a idea to check to see if this helps to fit the grill cloths better on your speakers.
                          Thanks Jason.
                          Thanks Jason.

                              • How not to *eat* M40.1s (hapy ex-M30 customer)

                                Well I finally have my dream speakers. The majestic M40.1.... in Rosewood no less!
                                Back in Nov 2007 on page 2 of this thread post # 28 as well as congratulating Alan on his new creation I stated that as a very happy M30 user this was what I would aspire and start saving up for.
                                I however expressed concern as the whether the 40.1s would work ok and not produce too much bass in my medium sized 15' x 13' x 8' living room.
                                Alan in the following post reassured me that they would be fine and even in post #35 humorously stated that if I was disappointed he would offer to eat them for me!

                                Well I'm here to tell you Alan that my M40.1s are off the menu for the foreseeable future. I love them!
                                After having to wait a few days before I had enough time. I fired them up for the first time this evening and all the minor concerns after having owned and enjoyed the M30's for six years instantly vanished.

                                After a 3 week gap from selling my cherished M30s ( to help fund the new 40.1s) to receiving them I was so reassured by how similar they were, The 40.1s reveal their extra present in terms of scale and effortlessness only when required otherwise they have all the clarity and focus that the smaller monitors had.
                                Even visually they didn't impose themselves anything like as much as I thought they would same hight just a few inches wider either side.

                                Here's to the next 20-30 years (hopefully!) of enjoying them! Also the Rosewood veneers are amazing.. more pics may follow. Thanks all.
