How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.

Manufacturer's notes
The AE100² is a compact stand-mount/bookshelf loudspeaker exhibiting qualities perfectly embodying those of Acoustic Energy. The AE100² has been designed with a view to achieving high sound pressure levels from a small enclosure. This is obtained principally through the use of a 130mm mid-bass drive unit built around an ultra-high force, long throw motor system.
The AE100² is a compact stand-mount/bookshelf loudspeaker exhibiting qualities perfectly embodying those of Acoustic Energy. The AE100² has been designed with a view to achieving high sound pressure levels from a small enclosure. This is obtained principally through the use of a 130mm mid-bass drive unit built around an ultra-high force, long throw motor system. Bass performance is augmented by a slot shaped duct allowing for a considerable cross-sectional area while negating the issues of air turbulence. A 25mm soft dome tweeter featuring our Wide Dispersion Technology completes the driver compliment and is housed within a 15mm HDF cabinet. Taking design cues from the award-winning 500 Series and finished in a choice of black, satin white or walnut vinyl veneer finishes. The AE100² is sure to look good placed on speaker stands or bookshelves, while delivering a sound that belies its compact size.

Our take on the brand
Acoustic Energy is a hifi speaker brand known for its unique 3.5-way Corinium design that separates bass drivers from midrange and tweeter, creating sound similar to a standmount speaker with a bass module. Their speakers feature distinctive materials like coconut husk-paper blend drivers and carbon fiber domes, along with specialized cabinet designs using inert mass damping to reduce coloration and enhance clarity.

Wharfedale
Wharfedale’s new EVO4 has grown out of the extensive research and development that produced the ELYSIAN flagship loudspeakers and borrows much of the technology involved in ELYSIAN.
Wharfedale is a speaker brand known for making high-end audio accessible to budget-conscious audiophiles, particularly through their Heritage Series and Diamond line which offer premium sound at affordable prices. Their speakers feature curved cabinets and are celebrated for their rich, full-bodied sound with excellent tonal balance, notably in their Linton 85s and Dovedale models.
Expand Details
.svg)
Our Summary
Product Strengths
- Excellent focus and separation, with the speakers 'disappearing' to create a natural soundstage
- Impressive low-end performance, adding authority to the music
- Cohesive driver integration, with no perceivable handover between the AMT tweeter, midrange dome, and woofer
- Remarkable neutrality in the midrange, with a detailed yet smooth treble—avoiding harshness even at higher volumes
- Clear and detailed sound reproduction, extracting nuances and levels of information outstanding for its price
Product Considerations
- Vertical off-axis performance of the AMT tweeter is not good, so correct speaker height and toe-in are important
- Soundstage is not super wide, with the presentation mostly between the speakers
- Some reviewers found the aesthetics or proportions to be awkward or not to suit all tastes
- Bass may be a bit polite for some listeners wanting subwoofer-type rumble
- The midrange can be fatiguing if the listener's ear is at the midrange driver level
Takeaway: The Evo4.2 is a well-rounded speaker that delivers excellent sound quality with impressive imaging, detail, and tonal balance. It is capable of providing an audiophile experience at an affordable price.

- Good midrange reproduction—clean and uncolored—especially for the price
- Clear and detailed sound with good separation of instruments
- Taut and agile bass performance

Reviews
Klipsch
Klipsch is renowned for its pioneering use of horn-loaded technology in speakers, which enhances efficiency and reduces distortion through their signature Tractrix Horn design. The brand's distinctive "Klipsch sound" is characterized by a bright, dynamic audio profile that some find exhilarating.
Expand Details
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.

SVS
SVS Ultra Evolution Bookshelf speaker represents the culmination of SVS breakthroughs in driver design, component materials, and cabinet architecture, married with a relentless passion for audio excellence. The science of sonic perfection in harmony with a love of convincing and immersive sound. With a big, expansive sound that's revealing and detailed, Ultra Evolution Bookshelf gives the impression of a much larger speaker without sacrificing refinement or accuracy.
Never has this fusion of design elements existed in a single speaker. Time aligned cabinet geometry, diamond coated aluminum dome tweeters, organic cellular lattice diffuser, and other advancements embody an uncompromising approach to speaker design. These innovations are brought to life with painstaking anechoic and real-world measurement and voicing. This final bit of artistry places Ultra Evolution Bookshelf among the highest fidelity speakers ever created.
Our mission has always been to ignite a passion for transcendent music and home theater experiences by rendering the truest sonic playback. The joy of pristine clarity, absolute transparency, stunning dynamics, and effortless bass for more people than ever. SVS Ultra Evolution Bookshelf deeply connects you to the emotion of sound.
SVS is a hifi brand known for its subwoofers that feature dual 8-inch voice coils and 17-inch drivers, delivering deep bass with precise control through their force-balanced woofer array design. Their Ultra Evolution series uses diamond-coated aluminum dome tweeters and acoustically centered time alignment cabinet architecture to ensure all sound reaches listeners' ears simultaneously for a coherent soundstage.
Expand Details
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.

Expand Details
Our Summary
Product Strengths
- Nice cabinets
- Fluid and captivating articulation in the mids, with warmth and clarity to voices
- The bass is good enough that one could conceivably get away without ever having a subwoofer
- Excellent clarity and tonal balance
- Able to use so much high-performance technology in products that cost so little
Product Considerations
- Has aluminum wiring
- Lacks a little bit of detail at the very top—kicks, punches, and gunshots do not quite have enough "snap" to them
- Rated at 8 ohms, but in reality, they are 4 ohm speakers
- Do not have magnetic grills, they have a pin-and-cup grill retention system
- Tendency to sound bright with modern pop and electronic music
Comparisons (according to reviewers)
- Compared to the SVS Prime Bookshelf Speaker, it is a noticeable step up in linearity
- The Ultra Towers' performance is beaten by perhaps only one or two other models in the same price range
- The SVS's more laid-back character and natural response remains composed compared to the JBLs, where the JBLs start to lose control and break up
Takeaway: The Ultra speakers are a good value because of their high-quality sound and build that offer performance often found in more expensive speakers. One can enjoy great sound without breaking the bank.

XT20

Released
2021
Polk
Monitor XT20 maximizes the enjoyment of music, gaming, and movies with lifelike, high-resolution sound and effortless bass. As the higher-performing bookshelf speaker in the Monitor XT line, the MXT20 can be paired with louder amplifiers and can produce deeper bass (a full half octave lower) than the compact MXT15.
Polk’s been a major player in the audio world since the ’70s, though they don’t always get the same attention from hi-fi reviewers as some other brands. But they know their niche—mass-market, entry-level products that perform way better than you’d expect for the price. Their R200 model, for example, gets called one of the best under $1,000. If you’re looking for solid performance without spending a fortune, Polk’s stuff is hard to beat.
Expand Details
Our Summary
Product Strengths
- Clear and natural dialogue projection for movies
- Impressive bass performance, especially in small to medium-sized rooms
- Good imaging, with elements well-placed in the mix
- Durable finish on the cabinet that is scratch resistant
- Engaging sound quality for the price
Product Considerations
- Treble can sound a bit two-dimensional
- The tweeter can be a bit harsh at louder volumes
- Bass is not very refined
- Simplistic box design
- They are heavier than expected
Comparisons (according to reviewers)
- Vs Cerwin-Vega LA-165s, the tweeter on the Cerwin-Vegas is better, but midrange driver from the XT20 is nicer
- Vs Sony SS-CS5, Polk gives nicer bass than Sony
Takeaway: The Polk Monitor XT20 is an affordable speaker that offers good sound quality, especially with its bass performance and clear dialogue, making it a great option to put smiles on people's faces when listening to music or watching movies. Its durable build and engaging sound make it a worthwhile consideration for those starting their audio journey.

(2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.
