The story of the Sibelius loudspeaker.

Harley Lovegrove, Technical director and designer of the Sibelius loudspeaker, shares the story of his passion for life and for music, and for the technology that brings a live performance into our homes. It's a story going back nearly 50 years and to his first encounter with a wind up gramophone!
(The intro. and outro music is 'Philia' written and performed by Stefan Meylaers, and taken from his piano suite 'The Four Loves').

Another great video of yours. How not wanting to at least listen to the Sibelius once after you hear such a lovely story! To feel your passion and your (very humble) joy and proudness to have accomplished your dream is really touching and amazing. That your daughter accepted the challenge to help her father make his dream come true is also great. Inspiring. Thank you.

[@LovegroveTraining]

This was a fabulous journey, one filled with passion and patience. [I am Damien, the younger brother that Harley mentions in the video] You and I are so alike in that we put our heart and soul into everything we undertake. The desire always comes from within. Most people call it passion. The many thousands of hours of thought and problem solving that we went through together in the early 80s often led us up the wrong avenue but we always took the route to its conclusion, never giving up early. The 'concrete' speakers that we developed had probably one of the most complicated crossovers ever built, but boy did they sound amazing. The design concept was to overcome weaknesses with ever more complexity. It's the same philosophy that formila 1 aerodynamisists use. I love that your strategy for the Sibelius has been to overcome weaknesses with ever more simplicity. It all makes sense to me. Taking the Sibelius design to its conclusion, the furthest point possible without accepting compromise along the way is a great achievement. Good work bro!

[@PearlAcoustics]

Thank you Damien, very touching. Where did the days go? What I love about the journey is the pride and pleasure our clients talk about in their personal stories about living with our speakers; especially from those considerably younger than myself! Take care, H

[@Coneman3]

Or you could have just made active speakers?

[@LovegroveTraining]

Oh yes, I did that. While I was at the BBC I designed and built active crossovers using a mix of discrete components and integrated circuits and I coupled these with Naim monoblock amplifiers but although they were amazing for small speakers they were not in the same league as my big brother's simple approach using nothing between the amp and the voicecoil. @@Coneman3

[@Trebor2024]

A lovely human story! I’m looking for some new speakers and need to audition a pair!

[@AdiMaco]

This is a story that is worth sharing. I always loved products from small companies, made by hand and made by people with passion instead of industrial products. I can not escape my love for philosophy and I would say that this kind of product has imprinted in them the energy life and personality of the creator and this gives to your speaker character and personality and life. These kinds of products are alive and they love you as much as you love them.

[@PearlAcoustics]

That’s very perceptive and extremely kind. Thank you 🙏

Really enjoyed your presentation of the Sibelius Speakers refreshing too listen to someone talking about audio without all the hyperbole one normally has to sit through.Mark makes superb drivers at an affordable price thats rare in high end audio! Have to agree after all these years and too many speakers to remember full range drivers i think are the way to go you dont realise what a detremental effect a xover has till you listen without one.Hats off to Paul Messanger /Martin collums/Alvin Gold ect over the years for providing us with excellent reviews.Please keep your videos going its like putting on a pair of comfy slippers listening to you.cheers

Thank you Brian! Your words mean a lot to me. I will definitely keep the videos coming. I have a long list of topics that I feel the need for discussing honestly and respectfully.

[@mosfet500]

It can't fathom how much our lives parallel each other. I'm older than you but when you reflect on your life it just brings back these memories of my childhood. People laugh today when I tell them that when I was eight years old my mother asked me what I wanted for my birthday and I said "a soldering iron". Seventy years later I still have it somewhere in the basement. When I was around thirteen my uncle had these two old mono tube receivers and I tapped off them to make my first stereo. I dug around and put together this array of speakers and it must have sounded like crap but everyone was amazed. We were dirt poor but we lived in a middle class neighborhood (USA). People would throw out all their old radios and TV's and I would come home constantly with pockets of tubes and speakers, whatever I could rummage from them. I never though anything of it. I was a horrible student, my father kept wondering how this kid could do all this stuff but couldn't pass school. We'll years later I went to work on the first top secret military computers, become an electronics engineer and write for all those magazines I used to run to the mailbox to get every month. I can't imagine what life would have been like if we had lived next door to each other! Great to hear your stories, just wonderful!

[@PearlAcoustics]

[@johnbrent3465]

Harley, you're a treasure. Your story about your fascination with music reproduction and loudspeakers beginning in your youth resonates with me (although, I haven't gone as far as you have). I can remember when I was about 3 or 4 being fascinated with my parents' DIY hi-fi system with a valve amp and remember my imagination getting a hold of me such that when I looked into to a very interesting valve, I swear I could see the Kay Kyser big band in that valve while my parents were playing one of his albums. I now see this as a kind of harbinger of music videos and wish I would have gotten into the music vid business based on this "visual prophecy." Anyway, I just want to tell you how much I enjoy your KZbins. I may, someday, purchase a pair of your Sibelius loudspeakers. They get really good reviews.

[@PearlAcoustics]

Thanks so much, Mr Lovegrove. Not only have I stumbled on your channel, but now Sibelius loudspeakers too. I'm now in a bit of a nomadic phase travelling mostly between Hong Kong and Malaysia. But greatly look forward to hearing these speakers the next chance I get in an audio shop in either of these places.

[@user-od9iz9cv1w]

What a wonderful story. Thank you for sharing it. I have come to know of the Sibelius through Thomas and Stereo's KZbin channel. Given this story of their history and Thomas glowing review I think these are a gem. If I move into a condo in my senior years and need to downsize, these will be the speakers I seek. BTW, I took similar path growing up on a farm in Canada. In the attic was an old gramaphone and some 78s which I listened to. Also marveled at the early tube radio. There also was some old battery powered tube radios. Now I listen to all triode DIY OTL amps. So, the tube is directly wired to the triodes which in turn go to very old alnico coaxial drivers with minimal first order crossovers. It is wonderful.

[@PearlAcoustics]

You’re very welcome! Thank you too for your story. I was right there with you in the attic! Enjoy your music

What a wonderful story. Normally I stay well clear of 'entrepreneurs' selling their latest get-rich-quick self-help book or video course - but this is (probably all too rare) a real example of genuine passion for an idea and the years of hard work to make it happen. I too, on the opposite side of London maybe 5 years later, also dialled up the airwaves to pull in distant stations from rescued and self-repaired valve radios, borrowed Gilbert Briggs (of Wharfedale fame) book on speaker design and set to designing and building speakers using units rescued from any surplus store/junkshop/factory seconds (including some KEF units my Dad managed to get for me). I also joined a London youth orchestra - and wanted to build something that sounded better than the KEF Celeste IIs my Dad had - that were faithful to the sound of the acoustic instruments I came across. Then, aged 10, I got sent to a boarding school and my tinkering had to stop - I'd almost forgotten those experimental days and you've just brought them back with a bang! I have to hear these Sibelius speakers one day - now that I fully understand the passion and commitment that lies within them.

[@PearlAcoustics]

Dear Bob thank you for your kind words and lovely comment. I got packed off to boarding school too, so I think we had very similar lives / backgrounds. I would love to demonstrate my Sibelius loudspeakers to you one day. Let us know (via the website) where you are and maybe there is someone not far from you.

[@grandmasterjo1]

One of the best stories on sound ever heard. I got my T27 from England and I was elated. Then in india nothing was available so this was the best gift in my life. I graduated to the B200 and I thought I now have the best setup. I built my cabinets with the my carpenter and realised my hand built Xover was a disaster. And I could not just get the KEF xover. My dream was to build the KEF 3way with the B139 with a transmission line design, which Ofcourse was never possible as like in England, I could never cross the street and pick up the B139. 😜🤣😜🤣 I was fascinated with KEF and this was 1975. I love your story and the nostalgia about KEF. Without hearing your speakers I can smell the clarity and the aesthetics in build quality. 🥂🥂🥂👏👏👏👏👏👏 If it still sells for £3000 I will buy the Sibelius without hearing them. Kindly revert.

[@PearlAcoustics]

As always another fascinating story And as I boy I grew up buying my first three band transistor Radio My friend gave me her old Gerrard with a ceramic cartridge My joy was getting two 12 inch full range Philips drivers and put them in bass reflex cabinets And then I got a T27 and B 110 Build my own x over going over to the British council library in Bombay for reference ( please note then in the mid 70s in india the duty on any electronic item imported was 350% thanks to the then PM indira Gandhi ) So we’re deprived of buying anything like you would across the road in England I could not get the x over from KEF so build my own counting the milli henry and ufd ( which was not very good 🤪) But the KEF sounded nice And so my story grew ahead with my Yamahas NS2000 M and the Thorens with the SME and Quad 405 and Nakamichi 700. But back to the Sibelius It’s mastery at its best for a single driver Is it the TL design that delivers the bass so good I have not heard the Sibelius yet but on my next trip to the uk I’m gona visit Pearl Acoustics just to say thank you to a passionate persevering perfectionist who delivers magic from a single driver 👏👏👏👏👏👏👏

Best wishes Belgium. Apologies once more.

[@7649angel]

@@PearlAcoustics Oh, I don’t mind being called Peter by mistake! I have been called worse! What I like about your story it reminds me of my own. I was born in the NE of England living next door to my uncle who was a brilliant musician and also a techy guy. He started building his own electronic organ before I was born in 1949. He was a piano teacher and church organist. I seemed to spend most of my time in his house as he did his tech stuff. He would record Classical music on to his tape recorder and I used to sit listening to quality sound from the age of about 2. Needless to say I grew up with a love of good music etc. Becoming an engineer for Hammond Organ UK just seemed the natural thing to do. While Hammond was focussed on sound generation in the main, on their Jazz Organs like the B3 they loved to overdrive their valve Amps. To be honest I hated that and I do still seem to be able to hear the slightest bit of distortion. I will shut up now, you don’t need to be pestered by me. Thanks again though for your excellent videos.

It was a very nice ☺️ journey of a story. You could say we must have almost similar beginnings in the world of audio. I did something similar with a woofer (mid-bass) with the same appearance. It stands around 48 inches and 13 inches deep. I used the driver from a speaker 🔊 company that Kef bought during 1990. I used their drivers because I can't find a good full range unit locally. I did not use their crossovers simply because I am using a 1969 Sony 7.5w per channel receiver. It was fun when I discovered the best sound from the right internal box configuration. I can relate to your story ❤️ and I hope to get hold of either your Sibelius speakers or even just the drivers themselves. I will watch your other videos. Warm greetings 🌹 from the Philippines.

Absolutely delightful video, and very interesting, Harley. I have been into hifi as a means to listen to music for the last 50 years and recognize many of the names you quoted, as a long-time subscriber to the British hi-fi press and as an occasional show visitor. I started building speakers, turntables and amplifiers in my teens. Shared a physics degree course with Andrew Jones and Arthur Khoubessarian (Pink Triangle now Funk Firm) Nice to have Sibelius on my radar for when my long-standing KEF References die of old age... Best regards from Switzerland, Rob

[@johnland7318]

Hi Harvey, ive discovered your videos and surprise your turntable list included my PL-12, long gone. Being a woodworker and also a budget hifi person, in the 1970s I bought a 20 watt Wharfedale kit, and with a free sheet of rough ¾ plywood and made the cabinets, heavy and airtight. 3 pairs of speakers, 2 cross overs and a new smarter pair of ¾ birch plywood cabinets later, over 40 years!! I think they sound great. The ply cabinets are shaped to look like the 1980s Microphase speakers but still to the original kit dimensions. Why do they sound fantastic as none of the present separates units from different makers cost more than £120 each, Its because I've got no comparison speakers available. The speaker placement and room acoustics are ignored, by missus, "I want it here, it won't fit on this wall" CDs or vinyl just sound 'right', 'clear', thru the now 40w speakers. And I'm happy!!

Our first record player was a mono Dynatron with a Garard deck and the first record with "Grocer Jack".....(An exert from a teenage opera) ..... and "The Sound of Music" !!!!! (And "Waterloo Sunset - Kinks) ... The next was 1979 and a Sony 33B music center that sounded semi hi-fi and i remember playing "Out Of The Blue" - ELO and "Abba" - "The Album" (wow production or what) . (Over the years the circuit boards just got old and it lost it's semi- crispness lol) (And the tape head went "fluffy") ... Then i just bought used hi-fi from a local hi-fi shop and it all worked fine. ... Me and a mate went to a hi-fi exhibition in Bristol way back in 1998 in a hotel and ???.... I remember a room of Japanese men with a crazy "electronic bank" ....(maybe £30,000)........ but walking past another room a valve amp just "jumped out" !!!! ...

I have a question about Lowther speakers. The voice coil has to be in either two or four layers, because the wire has to be wound come come back to near the cone. Are Lowthers wound with two layers or are they using a thinner wire and four layers? I believe it likely to be two-layered, but Lowther's are so different and they definitely have more turns inside the gap that most modern speakers have. They voice coil is only 1mm outside the gap. I believe this is the reason that they have such great sensitivity that usual.

Perhaps I should hear Pearl Acoustic loudspeakers :) I have dear friends and family living in Belgium (Brussels) but with the pandemic going on, I can't afford the risc of traveling. Perhaps one day... I'm building a dedicated two channel listening room (29 m2) in my new home, so I will be listening to different floor standing speakers. At the moment, I have a pair of lovely Amphion Argon 3L and I listen to all kinds of music genres (2106 CD´s and boxset and 200 vinyls). I am most into digital (CD, SACD and Tidal streaming). I've just subscribed this channell. I wish you all the best! :)

[@PearlAcoustics]

Thank you, very kind. And yes, one day I am sure you’ll get to hear them! When we have an ambassador in Portugal, I’ll let you know. Take care and enjoy the music.

I pushed an old radiogram bought for 5/- to the nearest bus stop. The bus conductor lifted it up onto the bus. Then placed it onto the pavement for me. I pushed it (it had castors) half-a-mile to my home. It still worked! c1955 in Bristol, England.

[@PearlAcoustics]

What a lovely story! Thanks for sharing

[@roberte.andrews4621]

It is said that the composer Jan Sibelius never smiled. He would like this speaker.

[@PearlAcoustics]

Hi Robert, judging by the photographs - I can imagine that! I have visited his house in Finland once and it was certainly in a very beautiful location. It was given to him by the state so he could work in peace. it’s hard to imagine him not smiling when he went on his long walks in the Forrest it is set in. But his music certainly makes millions of people smile. What a gift the state of Finland received back from him.

[@jbgriffin77]

Wonderful stories, but I can’t stop looking at the Rothko. 😮

[@PearlAcoustics]

😂 it was painted by my Mother, who was an artist in her own right. She painted it for me as a homage to the great man

[@AllboroLCD]

After hearing your lovely story I cant help but feel like an amplifier designed soley for the Sibelius would compliment them really nicely. A Pass design perhaps in an attractive enclosure w/ the classic wood blocks on the side matching the grain of the speakers.

[@PearlAcoustics]

What a great idea! We were thinking about finding the ‘perfect match’ but PassLabs would be an excellent companion. The thing about PassLabs is they need to cool down and wood is a big insulator! A problem for the team to solve 😉

[@AllboroLCD]

@@PearlAcoustics You get my general vibe though, something custom voiced and powered specifically to Sibelius. A unique amp for a unique speaker.

Fascinating story about a real product made by real people who has done many years of hard work in search of perfection. Well done! Saving up to get a pair shipped to New Zealand. Or can i get you to drop them off and set them up on your way through?😉😊

[@PearlAcoustics]

Now, that’s a thought. What the most ecological way of travelling from Belgium to New Zealand?! Thank you kindly for your appreciation

[@JLSGK]

Great story. Thanks for sharing. With so many people today focused on measurements and who will buy equipment based solely on measurements, I'm curious to know why you don't publish the measurements of the Sibelius speakers; I suspect that they measure very well.

[@PearlAcoustics]

Thank you very much for your kind comments. On our website, we give the industry standard information, ohm, watts, efficiency in db per metre, general frequency response etc, which has proven sufficient up until now. Interestingly, I don’t think we have ever had a customer ask us for more measurements than what the industry submits. Hope this answers your question?

[@JLSGK]

Thank you for the response. I was referring to the more advanced measurements that some reviewers will perform in conjunction with their subjective reviews, including those by Stereophile (and its associated publications), Audioholics, and Soundstage. With so much equipment available only online and from different parts of the world, it's difficult, if not impossible, for potential buyers to hear everything that they are interested in, and even if they can, its in a room different from their own. Your passion is evident and your theory is logical, but having some objective support might make it easier for someone to take a chance with thousands of dollars. The Chinese manufactures like Topping and SMSL have certainly jumped on this and provide substantial amounts of objective information on their websites. I agree that you don't see this from speaker manufacturers, and I suspect that in many cases that is because their speakers don't perform objectively well, but if a company's speakers do perform objectively well, then it might be a marketing advantage to also provide that information. ...and I'm not trying to start a war between the subjectivists and the objectivists like on your speaker cable post.

[@Justwantahover]

Your speakers sound good! I bet you are like me and don't like two ways and three ways. Mine are a bit of a compromise and a FR driver and a woofer so the FR cone doesn't move much (less Doppler) and I can crank them more. Cheers Big Ears!

Do you plan to make Sibelius speaker version using the mark audio moap(magnetic oxidized) full range speakers ?

[@PearlAcoustics]

Hi, we have made a pair with the white cones version MOAP and our voice coil, they sound just fine. Would that be of interest to you?

[@kinglear5952]

Another fascinating video. How big a sound stage is optimal for these speakers?

[@PearlAcoustics]

Thank you for your kind words. With regards soundstage, you might want to see my video on ‘loudspeaker placement.’ However, in short, it more or less up to you. The Sibelius drive cone is quite shallow, so it spreads its sound rather wide so you can go from just a few feet apart with the cones pointing straight down into the room to very ride. In one of our listening rooms they are 4,5m apart and I like to sit quite close in at around 4m from the central line. And there is no hole in the middle of the soundstage at all.

[@obscurazone]

Yet another gem of a video! I should be working but I can't help dipping back in and out of your channel with every coffee break :) too many coffees now ha! I'm a fashion designer of silk scarves, and having built my company from scratch, it always makes me smile when I hear other people's stories that sound so familiar. The dedication in your bones! and intimate connection with a singular goal. Most inspiring to hear your story.

[@ssleddens]

An off the shelf driver and a wood box....WOW is this a first?

[@PearlAcoustics]

Hi Steve. Thanks for your comment. Just to clarify, our driver is not an ‘off the shelf’ product but a custom made variant made especially for us. The ‘wood box’ is made from solid, 3cm thick, natural French Oak. I hope I don’t make out anywhere in the video that this is ‘a first’ except for the fact that it was designed with great care and with the expertise of a great many people. Sometimes, the best things in life are ‘simple’. Getting them to sound great, now that’s the hard part. I hope one day you can hear and see a pair for yourself and make a judgement then. Best wishes, Harley.

[@hafizullahsufi]

So... if you don't use a crossover, how do you keep the woofer from trying to tweet and the tweeter from trying to woof?

[@PearlAcoustics]

There is no tweeter or woofer. Just one drive unit. The drive cone is able to reproduce the entire frequency range. The design of the cabinet it is coupled with, amplifies its lower frequencies, just like blowing over the top of a glass beer bottle, or how a double bass can produce such a loud and deep tone, with just the tiniest movement of the bridge which it’s strings pass over. Its pure snd simple acoustics.

[@fonkenful]

Hafizullah; do some research on the seminal work by Ted Jordan.

It would be nice if we could hear demonstration of your loudspeakers on KZbin, and let us make our own opinion what think of your loudspeakers.

[@PearlAcoustics]

Well that’s an idea Kevin, but if course all you would hear is the equipment you are listening to them on. The best thing to do is to reach out to Pearl Acoustics via their website and they can see where your nearest listening room is and make an appointment for you. If you watch the Galion Amplifier video you will have a demo of the loudspeakers playing at the end of it. I hope that helps?

[@gerritgovaerts8443]

. Mark Audio is certainly quality stuff but full range is always at least 1 compromise too much for me . Transmission Lines bass is definitely a big step up from Bass Reflex , but nothing beats open baffle dipole bass for my taste. And if you want constant directivity then you have to look elsewhere . Bruno Putzeys cardioid dispersion design for Kii Audio is now used in a lot of studios . If you prefer dipole dispersion , then a very modern design with minimal (or no) baffle in the mid and high range is a very good alternative

[@fonkenful]

Gerrit, open baffle coil and cone or panel dipoles such as full range electrostatics or magna-planar types are not without their own issues in terms of room placement. I thinks it’s fair to say there are very few loudspeaker without some degree of compromise.

[@gerritgovaerts8443]

@@fonkenful fair enough , OB needs at least 1 meter from the back wall and 60 cm from the side . OB (sub)bass placement is however less critical than your typical monopole (sub)woofer . Just less interaction with the room : there is zero net presurre build up with OB bass , but also no room gain
