The new Reference 9 Our knowledge from over 50 years of speaker construction combined in compact and acoustically pristine speakers - the Reference 9. Equipped with the technologies of a floorstanding speaker, they offer the potential to fill even larger rooms thanks to the large mid-bass driver. The bass guide, used for the first time in a compact speaker, is an integral part of the speaker base and allows uncomplicated placement on sideboards or freely in the room with the ideally matching speaker stands "Reference LS". Thanks to precise tuning in the laboratory and listening room and the use of high-quality crossover components, the 2-way speakers offer great sound from compact cabinets.
Our summary

- Cabinet is reinforced multiple times internally to avoid resonances, even under high load
- Impressive bass depth for its size, with a balanced blend of low distortion, clarity, and rich bass response
- All-round sound quality, impressive volume, and craftsmanship
- Bass reflex system works with a sophisticated bass guide for controlled bass output without flow noise, offering placement flexibility
Product Considerations
- Careful placement is recommended due to potential negative effects on side radiation from nearby walls
- The production of the 'Black Ceramic Tungsten' material for the Reference collection demands a great deal of expertise
- Requires listeners to fully indulge in the music, demanding full attention and not tolerating distractions
- Computer-optimized cabinet design makes production more complex, time-consuming, and expensive than standard cabinet construction
Comparisons (according to reviewers)
- Vs Focal Sopra 1: Comparable in size
Takeaway: The Canton Reference 9 is a technically sophisticated speaker that delivers genuine high-end sound and immersive listening. It offers outstanding sound quality and craftsmanship for those who appreciate a premium audio experience.

Our take on the brand
R3 Meta redefines bookshelf speaker’s performance. Sharing the same drivers as the range-topping R11 Meta, the R3 Meta is a true three-way design. It has a 12th generation Uni-Q® driver array with MAT™ and a powerful 6.5” hybrid aluminium bass driver that pushes performance to new extremes.
Product Strengths
- Remarkably precise, unusually musical, and vivid sound, creating an open, inviting sound and bringing superb clarity and resolution to music
- Wide, airy, and holographic soundstage with excellent directivity, spreading reflections evenly for a consistent sound experience even when not in the 'sweet spot'
- Innovative Meta Material Absorption Technology (MAT) absorbs 99% of unwanted sound coming from the rear of the tweeter, leading to improved clarity, precision, and detail in the high frequencies—and better overall composure when the mix gets complicated
- A dedicated woofer handles the bass, allowing the coaxial system to focus on the important midrange without interference, which results in improved bass performance and power handling
- Neutrality and balanced frequency response, combined with excellent linearity, makes it very suitable for equalization, allowing users to adjust the sound to their preferences
Product Considerations
- The bass, while tight and tuneful, might not provide the 'gut punch' or chest-thumping experience some listeners prefer, and a subwoofer is recommended for those seeking more pronounced low-end dynamics
- The treble response, while detailed and airy, may sound a bit bright when the speaker is aimed directly at the listener (on-axis), and a slight toe-out (5-10 degrees) is recommended to relax the high frequencies
- Some reviewers note that they may sound a little flat or leaner at very low listening volumes, excelling more when given some 'juice' and volume
- The piano black finish, while beautiful, is prone to fingerprints and requires care to maintain its appearance
Comparisons (according to reviewers)
- Vs. LS50 Meta: Considered a better, more complete speaker with a more balanced presentation from top to bottom—and a more fleshed-out sound
- Vs. Bowers & Wilkins 705 S3: Puts the treble on a much tighter leash, while the 705 S3 can come on as just too much in that lower treble region
- Vs. Buchardt S400 Mark II: Is leaner, airier, and more spatial, while the Buchardt is warmer, thicker, and has more bass punch
- Vs. Revel M106: The Revel M106's directivity is nowhere near as good as the Kef R3 meta
Takeaway: The KEF R3 Meta is a well-rounded and high-performing loudspeaker, offering a detailed and balanced sound signature with excellent imaging capabilities. It is a great choice for those seeking a neutral and engaging listening experience.

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- Exceptional imaging and soundstage, creating an 'in the club' experience and disappearing from the soundscape
- High clarity reveals detail and dimensionality in recordings
- Beautiful aesthetic design with a deep gloss finish and well-executed walnut veneer
- Cabinet built with curved side walls to maximize interior volume and inertness
- Impressive bass output for its size, especially when paired with the right amplifier and placement
Product Considerations
- Can be a bit cool in the midrange and enthusiastic in the treble, requiring thoughtful amplifier matching
- Reveals faults in recordings and can sound a bit too much information at times—especially with compressed or poorly recorded music
- Lower sensitivity (85dB) means it requires more power to drive effectively
- While the bass is impressive, those heavily into bass may still prefer using a subwoofer
- The terminal block is plastic, which feels out of place for a speaker in this price range
Comparisons (according to reviewers)
- Versus Klipsch RP6000 Mark II, the Klipsch is fuller sounding, makes more bass, and is more dynamic, while the Vento has better clarity, dimensionality, and imaging
- Versus Buchardt S400 Mark II, the Buchardt makes more bass and is more relaxed sounding, but the Vento has more life and better transient attacks
Takeaway: The Canton Vento 20 is a well-designed speaker that provides excellent clarity and imaging, making it great for audiophiles who value detail and soundstage. Careful amplifier matching is needed to deliver a truly impressive listening experience.

Our take on the brand
Our Summary
Product Strengths
- Larger horn tweeter and a new Cerametallic woofer, compared to its predecessor
- Upgraded binding posts and crossover plate elevate to Reference Premiere status
- Larger diameter voice coils and aluminum shorting rings on the woofers give the speaker better linearity throughout the bass, decrease distortion while upping power handling resulting in improved speed and accuracy
- Better detail retrieval, more articulate bass, and vastly improved soundstage width and imaging, compared to the RP-600M
- The binding posts are the same that are found on costlier Heritage speakers
Product Considerations
- Finish options did not receive an upgrade over the outgoing model, leaving customers with the same ebony or walnut wraps
- The tweeter may be too bright for some listeners who are sensitive to a more aggressive top end
- Rated sensitivity is 94.5dB, which is a decrease compared to the original's reported sensitivity of 96
- Needs a bit of space behind them and to the sides, or at least positioning on open shelves, if the powerful output from that port isn't to muddy the sound
Comparisons (according to reviewers)
- Compared to the older RP-600M, the new sounds far more linear
- The new is very easy to listen to for long periods of time, and while it still has a presence, a speed and transparency to the artist or instrument—at least with respect to the midrange—it is not as forward sounding as past designs
- The new proved to be surprisingly flat, but best of all, not the least bit fatiguing
- There was very little difference in tone with respect to the mids between the new and a costlier Revel bookshelf
- These two are actually pretty neck and neck
- As for the Wharfedale Evo 4.1, the Evo is better constructed, not to mention nicer looking
Takeaway: The RP-600M II is a refined speaker with better components, improved sound, and better bass response and imaging. It's a speaker that would be great for someone who likes to listen to a variety of music genres and wants a good-sounding speaker that can last a long time.

Our take on the brand
Our Summary
Product Strengths
- Incredible power handling capabilities, performing as well as speakers in the $2,000–$3,000 range
- Sound quality is comparable to stand-mount speakers in the $1,500–$2,000 range
- Build quality is phenomenal for its price point, with real wood veneer options available
- Produces a dense and deep soundstage, especially for a two-way design
- Neutral and clean sound with nice extension in the upper mid-range to high-frequency extension, avoiding a 'hot' sound
Product Considerations
- Stereo imaging is decent, but not as precise as some listeners may prefer
- The mid-range can be a weak point due to some potential resonance in the upper frequencies of the woofer's range
- The speakers are not the easiest to drive and pairing with neutral, slightly warmer amps is recommended
- The treble response is slightly forward with some extra sparkle which may not be ideal for those sensitive to higher frequencies
- While the bass is good, listeners of bass-heavy music may want to add a subwoofer
Comparisons (according to reviewers)
- Vs. SVS Nano: The Ultra Evolution has a more open and expansive midrange and more linear bass, while the Nano has punchier—slightly boosted—bass
- Vs. Heco Salon Revolution 3: The Ultra Evolution is a good replacement since the Heco is discontinued, the Ultra Evolution favors neutrality, while the Heco has a warmer midrange, but the treble is very similar on both
- Vs. KEF R3 Meta: The SVS Ultra Evolution disappears better, but the R3 Meta sounds more neutral
- Vs. Dali Opticon II Mark IIs: Dali is warmer and more nuanced in the midrange but the Ultra Evolution is a little more exciting in its presentation
Takeaway: The SVS Ultra Evolution Bookshelf speakers provide exceptional performance for the price and create an immersive listening experience. They are well-built, attractive, and offer a balanced sound that makes them a strong contender in their price range.
