"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 may be for you. Either way, welcome to the world of Harbeth!"

    Thank you. That's very much how I see it.

    I could not have designed the P3ESR ten years ago. Or even five years ago. Such a project needs time, patience and maturity. Ditto the M40.1. [/URL].
    Alan is totally agree with this.. hm...I senses the new project on shl5 and m30 are there. It is is easy to name m30 as m30.1....How abt SHL5? SHL5ES?

    Btw, I just noticed the price of that "stand".....OMG!

    • M30

      the best argument (imho) for buying the M 30 /40 Series for the real enthusiastic music lover is to save much money, time , for seeking satisfaction in concert halls with bad acoustics , overpriced auditions, bad musicians, cold temperature outsides unnerving ticket can hooked up a pair, bring them in your room, pay attention to them and every week a compliment to each Loudspeaker , and so they will loves you and you them and your relationship will be growth the next 20 years.

      But be careful of your social life and your Familys support! You have to explain something about your new family members, and what they do with you, but your friends and your family will understand you after first introducing each other--;-) Thanks for building audio artworks to Harbethians


      • Being a relatively new owner of a (very) slightly used pair of M30's (in cherry finish), I've got to say that I'm thrilled with the sheer musicality of them. The ability of these "simple boxes" to unravel the music in a manner that is wholely enjoyable is rather uncanny.
        One thing I'd like to see, and perhaps someone can point me towards is some pictures of the optional wood finishes that are available for the M30 (Tiger ebony, Eucalyptus), I believe it's the Tiger Ebony on the main product page, but I'd love to see some higher rez pics of the other finishes.


        • . Please wait for the page to load. It took me 20 mins.


          • Thanks for that ! loaded fast for me... and I suppose I should clarify something I wrote above, as upon re-reading it.. When I stated "simple boxes" I in no way meant to undermine the technology within. The development of the Radial driver was a big undertaking, and it certainly pushes forward the ability of the speakers.

            What I meant by "simple boxes" is that , perceptually at least, the casual observer would dismiss the Harbeths as being too "vintage" in styling, and not utilizing alternative materials and shapes to accomplish the goal (I guess in Brit speak.. it's "missing the shiny bits" .. hehehe) but, the proof is in the pudding and the joy of listening to them speaks volumes to what's really going on inside.


            • Hey, Double D

              I, too, own M 30's and absolutely love them. Harbeth does a great job with the wood veneers and sadly, never really shows them off on their site. Here's a link to a picture of a single HL 5 in eucalyptus-my favorite Harbeth veneer


              My 30's are in the rose walnut finish-interesting, but nothing fantastic. My Compact 7 Es-2's are in a fairly rare and in this case, spectacular maple finish. If I could ever figure out how to post pictures of my Harbeths here on this site, I'd get them up!

              Cheers, enjoy the music!

                Hi, Alan,
                I understand that there is only Monitor 30 and SHL5 were fitted with RADIAL driver at this moment. May i know whether these 2 model will be upgrade to fitted with RADIAL 2 driver?

                Have you experiment on the both driver fitted to the same cabinets in Monitor 30 and SHL5? I'm curious to know what are the different in between them.


                • M30 Active

                  I wanted to know some details about the Monitor 30 ProActive. Could you post a photo of the back-amplifer panel? Are they bi-amplifed or are they only powered (one amp and passive xover)? Is the amplifier similar to the one for the BBC LS-5/9 (BBC AM8-17)?

                  Thank you in advance,
                  Harbeth fan, from Argentina.


                  • The M30 active is not in production at this time. Harbeth is concentrating on making passive speakers, without built-in amplification. These are much quicker to build and test, and give the user maximum flexibility. He can chose any amplifier he/she wants.

                    We do not know what the "BBC AM8-17" is so we cannot comment on that.

                    . We have found information on the AM8-17. This seems to be a general-purpose bolt-on amplifier module, perhaps designed to be affixed to the rear panel surface or to sit on top of the speaker cabinet.


                    • My harbeths make my children smile. Thanks.

                      After a half year with my Harbeths M30, i could say, thanks. In every kind of music( even in DVD Surround Mixes), the Music, voices, tones was simply there in my room. no highs, no lows, no complicated positioning, i could use them like an every day product, just like...mmmh my car...i never think before start the car about technical, fuels consumption, i simply drive it. And now all Family Members use the Harbeth, my Children are sitting sometimes near in Front of them, no pain in ears, only a smile lighted up her face, the Harbeth are Family Members from now on, and i'm sure they will stay longer in my home than the kids.


                      • Thanks for M30!

                        Having just really enjoyed another six hour plus music session ( today's a weekend day for me) I just wanted to reaffirm , not that it was ever in doubt, how much I love my M30s! Both in their performance and looks. Thank you Alan and the Harbeth team!

                        • M30 - sound wonderful

                          I have my new demonstration Harbeth Monitor 30 speakers in Maple, they have been playing for 4 days now and sounding wonderful.
                          I have them powered by the Pass Labs XA100.5 mono blocks matched with either the Quicksilver valve preamplifier or my own Parmenter valve preamplifier.
                          These are very special loudspeakers & very highly recommended to all music lovers.
                          Thanks Jason.


                          • M30 + leben CS600

                            I wondered if anyone has used M30 speakers with Leben CS600 amplifiers? I am thinking of replacing my current speakers with M30's. My current speakers are System Audio Explorers. They are far too big and have too much bass for my new flat. M30's would seem about ideal. I am about to arrange a home demo. Hopefully they will give a better integrated sound and a smoother top end. It would be interesting to hear from anyone who has heard this combination.



                            • Sorry for replying so late, but I have heard the combination and it is stunning. But do exchange the stock power tubes with EL34's...


                              • AM8/17 amp

                                I think the AM8/17 was (usually) a Quad 50 which was built in a 303 style case but with only one power amp in, with the possibility of a 100V line output. I somehow don't think this could have been bolted to the back of an LSU cabinet . have a look on the BBC anoraks site!
