I am not often lost for words but I am humbled by Thomas’ review. The Sibelius success is the result of very hard work by an amazing team. Thanks everyone!

Jean Sibelius is one of my favorite composers. I would have been sorely disappointed if the speakers named after him did not live up to his greatness.

Thomas is without a doubt my favorite audio reviewer on KZfaq! I love his approach and the way he addresses his videos. I also think his ability to work with and bounce ideas off of his close audiophile friends (who bring different perspectives to the table,) is extremely helpful for us all! Keep it up man!

Nice. Anticipated that review a lot. Keep up the great work Thomas

I’ve been looking forward to this review and it did not disappoint. So thoughtful and incisive. I love how well Thomas knows the audiophile community and the many preferences and tastes of its members. He never speaks in absolutes and always provides context (and great stories) to describe what he hears. I, myself, am not a fan of hyper-detailed speakers like Focal, but Thomas always acknowledges that it’s “all a matter of taste”. This is yet another reason that I can always trust what Thomas says - despite the fact that we have different tastes. I believe this is also why Harley chose Thomas to review his magnum opus. Trust. Credibility. This speaks volumes as both are men of the utmost integrity. Keep up the great work!! ❤️

Speakers to love! Great review once again Thomas!

Very well done review Thomas, you’re becoming so polished and so professional. 👌

Thank you so much for all of the details and your friends’ perspectives. I’ve wanted to know about these for a long time.

Another informative, thorough review. Thanks Thomas. These speakers are very intriguing.

That was a thorough review and you obviously enjoyed making it. Those speakers are beautiful in terms of the cabinets and I trust they sound nice too. Also seem very practical as to size and driver location. I like the cover for the driver too very cute.

Hand clapping that sounds like raindrops! So true, good one! Amazing video as usual, Thomas. Keep on with your passion. You’re an inspirational guide for so many of us. 😌👍

You nailed it Thomas. Very passionate review and fun to watch! The fruit analogy was funny too!! I would say this is my favorite of all your reviews.

Ohhh, NOW you're getting good at this. Well done!

Recently found these as well the Pearl Acoustics you tube page. Like Thomas its quality content. Thanks guys ! I hope to listen and possibly purchase these some day. The story on these alone is worth the price of admission..

My first review of this channel and wow!! Thomas has such an inciteful and engaging narrative style. Not to mention the huge breadth of knowledge and equipment pairing. This really made my afternoon. Thank you. 🙏

Thanks to your stellar review, am seriously considering the purchase of these loudspeakers. Wonderful presentation Thomas!

Thanks for your truly great review. I do really enjoy your videos, Thomas!

Great review! I’ve had my eye on these for some time now.

Your best review to date!! Nice work my friend.

Harley is such a humble audio genius. I never heard his speakers but will do it on first opportunity. All he says is so passioned and heart touching that I can not doubt these speakers are perfect for his vision. And this is why I want to hear them. To get his vision.

Excellent review Thomas!

Thanks for the video Thomas very interesting video .

Great review. I’m a cube Nenuphar mini owner and love them. If I even had to downsize these would be very high on my list.

I like the content of your channel. Take care. Greetings from Germany.🇩🇪

I have the eclipse tds and loving them so naturally I m looking forward hearing these pearls:)

Hey Thomas, great to see a review on these, have viewed pearl's youtube and alway's wondered how stack up. Just visited the Tampa Audio Show so as you mentioned would love to see you at one of these showing off your amp and system. Good luck with your AMP. Take Care

Thomas, the dad joke legit put a smile on my face. Great way to start the morning.

A masterpiece Thomas and friends!

Great review Thomas

Great video Thomas.

Great review! Thanks to Thomas’s info on his intended review on the Sibelius from his Patreon post I ordered a pair in December to try as the demo video sounded very good and seems to be full of body. My Sibelius arrived 4 days ago and I’m very impressed. It’s exactly as Thomas’s review. It’s quite amazing what one 4” driver can produce with a proper design. The whole range of frequencies is all there. Focus is on the midrange and the highs are never harsh which is much to my liking. The bass texture is very good especially double bass. The surprising thing is playing back blues and rock. Due to the lack of harshness in the highs it’s very enjoyable. Acoustic instruments and vocals are outstanding. I’m still burning them in and trying to find the best setup and hopefully they’ll get even better! These speakers are taking the place of my PMC fact.12’s currently and I don’t feel they are inferior. Many thanks to Ajay for his great service.

Great review Thomas! As a MarkAudio DIY speakers owner I agree exactly with what you have said. Its incredible what those small drivers can deliver when box design is perfected.

Thks for the Avital recommendation, a sonic treat

I am saving for this over the next 3 years. My next speaker.

Another amazing video, Thomas! Many thanks for all your hard work from everyone at Pearl Acoustics! I'm honoured to be part of the team at Pearl Acoustics 😀

A very fine review sir thank you .peace

What sold these for me was Thomas saying effectively "although these are not technically perfect, they are really nice, musical speakers, to listen to" and at the end of the day that matters WAY more to me than technical perfection. It's a bit like valve amps are not technically anywhere near as perfect stats wise as transistors, and yet so many people love their sound...

Very good, one of the things you do well is get your friends opinions, which really helps shape my thoughts of how I might perceive the sound. Along with switching amps. Still waiting for the curtain call with the stuffies.

Thomas great review! Nice to see a single driver speaker you like. I have never cared for them, but there is always a first!

Thank you for this one my friend. I love Harley and now I love his speakers.

Nice review video Thomas related to Sibelius

Thomas, your review of these is spot on. I Have owned and loved these speakers since May 2021. The level of musicality, detail, and instrument separation is phenomenal. But to me, what I love most about the Sibelius is how the tone/timbre of the vocals emotionally draw me in me in to where I close my eyes and think wow! this is beautiful; My love for these, however wasn’t immediate. I worked with Harley for about a month when I got them until really I heard what they had to offer. In fact I brought in a pair of QAcoustic Concept 500 and a Rel S/510 sub during my trial period to help assess what was going on and as potential alternative solution. Long story short, the synergy with my room was my issue and I can only theorize that in my extra large open space the bass was getting lost, along with the beautiful tonal character when I was outside of the main listening position. However, when I moved these speakers to their current location, a 15x25 listening room/guest bedroom, it was truly a wow! moment. I chose this setup over the Q acoustics every time I went to listen. The sound just drew me in. I returned the Qs as I clearly preferred the Sibelius, and I returned the Rel as I do not find any need to append to the existing bass. And back to Harley for a moment. He was absolutely great to work with and provided me with continual support and advice during this period and on. He was genuinely concerned with making sure these were the right speakers for me, and they are. I hope this helps some others who are contemplating a purchase.

i loooove my eclipse speakers ... single driver ... your review of the sibelius reminds me of them

Very nice job Thomas. I can understand why you liked this sound so much. I spend many hours a day in my 2014 Chevy pickup with 6 full range Bose drivers and a Delco CD player. Must be about $100 worth of parts but it sounds very coherent and warmer than my home system which is no slouch. Nowhere near the definition but we’ll balanced w/o tone controls and easy to listen to all day. The main reason I won’t part with this 260 K truck. It still looks newish. No more CD players in vehicles.

Thanks Thomas!!! I personally love 💘 single driver speakers. I love the pinpoint accurate sound. For me I think it's more a nostalgic thing. All my 1st stereos had single driver speakers. I love the the way these speakers look. Cheers Thomas!!!

Great, now I want one of those and a Luxman amp…. Nice review for sure.

Thanx ! Insightful and, as usual, pertinent and humorous !! By the way, still waiting ( or hoping ?!? ) for the Apertura Swing Evaluation !

I built my own 1 driver speakers back in the 70's. They were the so called transmission line system. The sound was fantastic.

I’ve never listened to the song you also demo at the end of your videos to demonstrate the voicing of the different speakers you review. But I did and man it sounded like 50x better on tidal than over KZfaq. I was surprised how much better it sounded and is actually a pretty badass song. My girl and I were getting down to it and laughing at the same time picturing you getting down to it also.

One and only Thomas!

I have never listened to these speakers, but in Harley's sound demo and your descriptions, they seem to have really nice details and tones. How well do they handle power/ dynamics and complex pieces with multiple instruments🤭🤔? Thank you for all your hard work on this review💪 I hope Harley can give you a good deal on his speakers🤞🤞🤞

Mass loaded tapered quarter of wavelength tube speakers are great! I built one and I am impressed by the natural, life-like sound you get. And yes, you get good bass response.

Hello Thomas. Gee, that sounds like we are long lost friends. I think this is one of your best videos and I really enjoyed your approach. It was informative, not hype, not judgmental, and best of all, the dad humour. I started exploring speaker options about 6 months ago, (not happy with my current set-up). I crossed paths with single driver/full range speakers. Something I had no real knowledge of. I was intrigued. That is when I discovered and started following Harley's channel. I am happy I did. Your assessment of his approach is spot on. The fact that Harley reached out to you also makes sense. I immediately went down that rabbit hole of reviews and videos and much much more regarding single driver/full ranges speakers. Information overload. Analysis paralysis. Your review couldn't come at a better time! I feel more informed and have a greater understanding of what this speaker type is all about. Not to mention the high praise for the Sibelius. Overall, a sound that appeals to me. Thank you Thomas. Ps; not to take away from the Sibelius, though Gershman Acoustics have been using live music and playback to design and develop their full range speakers for years. Full disclosure, I own a pair of Gershman R1s.

Rarely do one see a hifi review with such enthusiasm and passion, while providing candid and thorough insights all at the same time .... and i agree it make perfect audiophile sense for Thomas to become a distributor of the Sibelius in his area 😅

Thomas, I hit the like at the cat reference... mines just had a go at the turntable last night. LOL. I'm glad to have your (and your friends') feedback on the Sibelius, I was wondering about these speakers. Cheers, Janos

I am happy for you Thomas. Finally you have the chance to keep a set of fine sounding speakers. Get the opportunity to re-evaluate the different type of amps you guys have. Perhaps this is the right times to use class Dustbin trashing D gear. Tell your friend mr quad that I had the quad 63 and the 57. Got rid of the 63 and kept the 57. Heard those in a friend house in Europe and sold the 57.

Wow! Awesome Review. Hope to win the Lotto! I loved the sound demo and the expression of the music.

Another Great video. Thank You…s

When I worked for harley, first pair I installed replaced magnepan 3.7. Cabinets, work of art. These have flesh texture and body.

Great review! Great remark on how double bass should sound and about maggies and cat 👍👌😂 Very glad for Harley to produced such a great speaker. I hope for some big bookshelf variation of them ;)

Very cool

I had a similar experience with Grado headphones. I kept trying more and more expensive models hoping to get to one I liked. After many years I've realised it's just not the sound signature for me. The great thing is there are headphones for everyone.

I’ve been waiting on someone objective to review this speaker. I have wanted to hear these for two years. Now, at least I feel like I could give them a chance and know what I’m in for. Thank you for your thorough explanation on exactly how you arrive at your conclusions.

What Thomas said about Maggie lovers is spot on. I first fell in love with them in 2005. Since that time, there have only been two "box speakers" that I loved enough to buy - the DeVore Fidelity Super 8, and current my NOLA Boxer s2's. (And of course I still have two pair of Maggies...nothing could ever make me give her up! Lol) Great review, Thomas...that Sibelius looks beautiful!

Hola Thomas. Gracias por tus apreciaciones. Creo lo haces con gran honestidad, y el hecho que extiendas tus análisis a las opiniones de Mr Jazz o Mr Kanta o etc, enriquece el análisis. Soy partidario del trabajo en equipo y tú lo haces. Un agrado y saludos desde el sur del mundo. Alguna vez has revisado o has pensado revisar los Orangutan 93/96 Devore?

Great review. I am in the process of putting together a diy Mark Audio Alpaire 12p / KJF audio super pencil set speakers. The damping material sounds like the secret sauce.

That dude's channel is fantastic. I wondered what his speakers sound like. This is the kind of content I'm subscribed for

certainly You did gave a lot of flowers to that speakers :)

Very nice.

I don't doubt your impressions of the SIbelius sound qualities. When I first saw them these they reminded me of iterations of the cabinets used with the old Jordan JX192 driver from ~20 years ago. They were surprisingly impressive sounding given the smallish drivers.

Very interesting review. For me it is particularly interesting because my OB speakers use a Mark Audio CHR-70. When I saw the pictures of this speaker the first thing I noticed was that the drivers look identical. Even though the drivers in the Sibelius are specially crafted for it the old MA drivers I used also strike me as having a very well balanced voicing (I have spent a lot of time listening to and even playing actual instruments at a very amature level). They are not very efficient but in a reasonably sized room they can give a very musical reproduction. In my case I needed to cross to a helper woofer at around 200Hz due to the baffle losses but with a fairly simple crossover I still get a lot of the advantages of a single driver. I appreciate speakers of various different designs and philosophies much like I appreciate different kinds of music (except urban) for their own strengths. My current interest in high efficiency systems so will be experimenting with different multi-way systems but I really do enjoy the musicality of single driver designs very much. At some point I am sure I will play with transmission lines such as the Sibelius as well.

Thanks for the great review. I would love to hear how these compare to the new Fern & Roby Raven Iii's. Given the walnut cabinets with them I would imagine you might also get some great sound.

This guy is single handedly gonna break my bank

Thomas, it literally sounds like you were describing the Technics EAH-60 earbuds in LDAC mode. Even they are a single driver speaker with exactly the same qualities as these speakers. The claps are so realistic on these earbuds and I ended up buying 3 pairs

These could very well be "end game" speakers for everyday normal listening levels. Harley without a doubt is producing these for all the right reasons and given the means, Id buy these based on his experience and passion for music alone!

Great video as always Thomas! How do these compare with the (I guess similarly priced) Q Acoustics Concept 500s? Looking forward to your reply :)

Wonderful review Thomas. You and Harley are both great story tellers. Would you ever consider reviewing La Scalas? I can’t remember you ever reviewing a heritage Klipsch.

Totally agree about the clapping sound. So many speakers make it sound like frying bacon to me. They just don't get it right. Probably one of the very rare times where something with bacon in it isn't better.

Like you Thomas I to wasn't sure about single driver speaker's, but these look beautifully made and have grabbed my attention. I've seen his channel and read about these speakers and all sounds interesting. I am more of a two way speaker fan with subs myself, but would give these a listen to compare, as the Mark Audio drivers have an excellent reputation 😊

Great video Thomas. Do visit Penang during the durian season, I'll bring your family out for a durian buffet at the orchard.

As a subscriber I'll have to admit I'm a little dense. I never could figure out why you always signed off with a song that to my taste had way too much reverb in the vocals until I watched this video. You actually are playing the equipment you are reviewing so it could be compared to other equipment reviews (dugh!). I know you put up the listed equipment in a box describing it but like I said I'm a little dense. The reason I FINALLY NOTICED it was the sound of the video compared the others I've heard was significantly better. The voice became the prominent focus while the reverb was an enhancement which hadn't been the case on the other reviews I'd listened to. Thanks I found this review very helpful.

Thanks for doing this review. I think you have convinced me to buy this.

My fav review of yours so far! Great job on these. I’ve never heard them but started following Harley 6 months ago and adore him. I’d love to hear your thoughts on Devore as well!

I would check out voxativ speakers if you have the chance Thomas. Excellent single driver speakers. Thanks for this great review!

Very nicely done video Thomas. It’s apparent how much careful work you put into it. Harley is going to have a challenge keeping up with demand from the numb this video will give him.

I don’t know the sound of the Sibelius. But the way they are developed, crafted and delivered promises a lot. I am totally happy with my LS50 Meta’s, but I guess the Sibelius would make a nice replacement as I love special design. Maybe I could listen one day somewhere in the Netherlands.

Those covers are a nice touch.

To me, it would come down to the type of music you prefer listening to. For chamber, choir and other classical music, or modern acoustic music, these speakers may function exceptionally well. But for the full modern band music that I mostly listen to, with modern drums and electric bass, they may not please my ears. Great review, thanks for doing this.

Judging from the rectangular terminus opening / port on the front, it looks like it's a mass loaded transmission line speaker. And that is consistent with their description. And that is a very good thing!

You're spot on about the Focals. Even though they're just entry level 706 bookshelves, the top end is very bright and detailed but kind of obnoxious if you set them up in a traditional way. My solution was less toe-in, on top of the RB27s, upside down, and about 1.5 inches of elevation on the back just to get them slightly pointing downwards.

My ex got rid of one of the cats she had. It was climbing my Maggies. The other cat didn't mess with my speakers. It's nice to know I now have a new option if I have to choose between an animal and my speakers.

Great to hear you confirm everything that Harley says Sibelius is. I would love to hear them too!

Thank you for the great review! I am very intrigued by these. It seems like they are great for classical music, but how do they handle BIG orchestral performances? Will they reproduce, say, a Mahler symphony convincingly?

Another great reviewThomas!!! ❤️ Thanks for sharing your impressions, the time / work that you and your friends put into auditioning especially about amp influence. I've looked at them before. This may be the speaker for me. Different amps sheding slightly colored light on music - intriging. For my tast most good speakers that I have auditioned don't replicate the tonality of akustic musical instruments or that overall tonal balance which emotionally pulls me into the music. They emphasis other things, tonal information, detail, base. It's all about individual tast and emotions isn't it. Keep enjoying what you do and tell us how your amp/baby pairs with these and others (we're curious). 🤗 Best Zack

SAF. Awesome. The spouse approval factor must not be underestimated.

I recommend Sibelius Symphony nr. 5.. 👍🏼

Hi Thomas, amazing review thanks! Did you happen to test the Sibelius with any CAYIN tube amp?

Great review Thomas. Have you listened to the Omega line? I have the super 3xrs and they are fantastic.They are also single driver. I love Spica and the Maggie lines. The Omgas are outstanding too.

Hey Thomas this my first day watching your videos and right away i had to subscribe! Very informational ! I have a question i was wishing you help me ! I recently bought a HD 800s headset and was wondering what we be a GREAT amp and Dac that i can push all the performance out of these headsets ! ( tube amps is something i look forward too) - as-long as it gives clarity and decent bass ill be Happy ! I never heard a push pull or single . Mind you .

Man single driver speakers definitely have some unique and interesting characteristics, but like you they never really wowed me. Sounds like I'm going to have to find a way to listen to these.
