Congratulations on an awesome product. As a long term member on Diyaudio we have discussed this speaker there too. The general consensus is that it’s an ML-TQWT using Alpair 10 drivers. I don’t remember the details Dave (planet 10) is the full range guru there. I have had the opportunity to listen to other TQWTs using 3-4” drivers (from Fostex and Tangband) and while they present a very coherent soundstage they are limited in the SPLs they can achieve. Is there any option to supplement the bass using a bass driver that can integrate with such full ranges?

@PearlAcoustics

2 жыл бұрын

@@navinadv Hi, thanks for your very kind words! Personally, I do not see any reason to supplement the bass as they go way deeper than most floor standers (still flat at 38Hz.). However, if you want to play them at deafening levels, then you might want to use a amp with a programable sub and speaker out so you can roll off what goes into the Sibelius, but then you’ll ruin what they are designed for. Hopefully, you’ll get a chance to hear a pair one day and decide for yourself. Best wishes

Thomas is without a doubt my favorite audio reviewer on KZread! I love his approach and the way he addresses his videos.

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!! ❤️

Music and hi fi sound systems are all a matter of Personal taste. I have a pair of Focal Chorus 726 speakers ( they are no longer being made) in my set up, absolutely love them. Had the opportunity to listen to some current generation Focal speakers powered by a Naim Unity Atom, my god I thought they really sounded terrible.

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.

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

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.

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.

Box design has virtually no impact on system below 200 Hz, baffle diffraction can cause issues about that (not box design) and a relatively large single driver design has lots of diffraction issues at higher frequencies as the signal propagates over the driver's suspension and frame (the Sibelius reverse single roll suspension is designed to clearly minimize this but it does not eliminate it).

The enclosures are designed by myself, but Dave at Planet 10 designed the internals which sport front to back braces incorporating four high ratio rectangular ports, rear firing.

I've respected Pearl Acoustics and their informative videos.

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.

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...

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.

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.

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.

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.

The Pearl Acoustics web site says "internal front loaded, quarter wave ‘V’ horn". The one photo they have of a cabinet being built, has a glimpse of what seems to be a vertical slot about midway on the side. This would point to an internal vertical baffle, that *may* taper to a point against the front baffle, that provides a resonance chamber. The 'V' channel is inverted, with the driver at the "fold" at the top. One end of the 'V' is closed, and the other end is the opening at the bottom front. For all intents and purposes, this is a folded bass horn aka a transmission line.

After talking to Harvey Lovejoy 5 years ago, and hearing his speakers at the Munich audio show 5 or so years ago, I bought them sight unseen. They were not broken in! After a year I finally after a year I had a true audiophile friend listen to them! He pronounced them outstanding. So I moved them to my living room and broke them in for another year. Today a few minutes ago I hooked them up to my Streamer, Giselli lab DAC, and Rogue audio pure tube amp: what a revelation. Using Spotify high end ! To my audiophile friends, I am begging you to get the Cannonball Adderley quintet "74 miles away album from the 1967" and Hang-on Ramsey from the Lighthouse in Hermosa beach from1965. I was there for the recording's both night s this is perfection! Like Harvey says it is like being there.

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.

@@ThomasAndStereo I find it has really good rhythm compared to other amplifiers I’ve tried. Its true to the source, neutral or maybe a few DB boosted on the low end which I like. There’s ample power for only 100 watts. I came from separates Mcintosh. I also like that it’s Canadian.

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

Hello Thomas, the test sample at the end … are the levels matched between both recordings? The 340i sounds considerably better (in my opinion) as compared to the Luxman. Excellent review, I might be wrong but I think you are incapable of hiding your emotions. Your excitement and appreciation of the Sibelius speakers shines through on this video. Brian

Thanks, I did not level match them but if you prefer the 340i demo, yeah sure, it sounds great too.

It is a matter of taste indeed :) I like the luxman sample better as I found the midrange of the 340i feels slightly drier. Now I am curious how good the midrange with 300b in comparison

@@HercahyoAdiSaputro Of course, go with what you like 🥳🙂… I’m still surprised how different each amp sound through the Sibelius. Makes me want to try the Davis Acoustic MV One Master Brian
