What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Our take on the brand
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.

Reviews
Focal is a French hifi brand that makes their own drivers in-house, including their highly-regarded beryllium tweeters and unique slatefiber mid/bass drivers made from recycled carbon fiber. Their speakers and headphones feature distinctive technologies like their "W" sandwich cone design for optimal driver performance and Mimi Sound Personalization that adapts audio to individual hearing profiles.

.svg)
Product Strengths
- Sweet and detailed audio performance with clear instrumental separation and expansive dimensionality
- Warm and full-bodied bass and midrange
- Clear yet 'mellow' treble, creating a pleasing sound signature
- Accurate sound that doesn't do much to color the recording, so listeners get a balanced presentation of the source content
- Good level of dynamic range for reasonably sized bookshelf speakers, and they can get louder than expected for their size/price class
Product Considerations
- The laid-back sound may occasionally obscure some definition
- The speakers run on the cooler side of things, never becoming too indulgent in any aspect and instead providing a sound that is accurate and slightly pulled back, but never muted or lifeless
- Asymmetry of the phase coherence of their vertical lobe can be a slight problem for anyone listening under the tweeter axis
- Does not feel as substantial as some other speakers in their price class
Comparisons (according to reviewers)
- Vs Focal Vestia No. 1: Theva offers a lot of what makes the Vestia No. 1 great while saving money, but is not as immediately striking in detail or treble extension
- Vs Bowers & Wilkins 606 S3: Theva is more compact and easier to place, but doesn't look as premium
- Vs Polk Legend Series L100: Theva has a more laid-back sound profile, making it a better listen in most cases, while the L100 presents a more precise center image
Takeaway: The Theva No. 1 is a great speaker for enjoying detailed and smooth sound without harshness. It's a good option for different types of content, from music to movies, and is especially suited for smaller spaces.

- When used on top of floor standers, they do not sound as good as when wall-mounted
- Dolby Atmos content availability may be lacking

SVS
Ultra Evolution Elevation
449
/
Released
2024
When SVS first launched the Prime Elevation speaker, it turned the home theater world on its ear by delivering a direct radiating Dolby Atmos height effects speaker that vastly outperformed any of the conventional "ceiling bounce" models and in-wall speakers. Since that time many brands tried to copy the approach, but none could deliver the total package of performance and versatility. For this reason, it emerged as one of the most popular home theater speakers in the world paired with all different brands. Ultra Evolution Elevation is a larger, higher fidelity version that unleashes greater dynamic output and deeper low frequency extension.
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
- The Ultra Elevation speakers offer a more substantial and impressive presence compared to smaller speakers
- They have magnetic grills, which are convenient and prevent scratching the cabinet
- They maintain the neutral SVS voicing, ensuring they blend well with previous Ultra and Prime series speakers
- The sound is refined and neutral, allowing listeners to focus on the music without the speakers drawing attention to themselves
Product Considerations
- The speaker cable terminals are flipped, which might require shorter or 90-degree banana plugs depending on the mounting
- The Ultra Elevation speakers are heavier, requiring secure mounting—preferably anchored rather than relying solely on drywall screws
- These are supporting speakers and still require dual matching subwoofers for the best sound experience
Comparisons (according to reviewers)
- The Ultra Elevations are bigger, heavier, and have a better driver and offset rear port compared to the Prime Elevations
Takeaway: The Ultra Elevation speakers are a worthwhile upgrade that integrates well into existing SVS systems to complete the sound. These speakers deliver refined, neutral audio, making them a delightful addition to any home theater setup.

Our Summary
Product Strengths
- Offers a clever and affordable solution for Dolby Atmos support

- Adds a vertical axis to the sound, bringing immersive audio to the home
- Offers flexibility to build a custom home audio system
Product Considerations
- Sound is meaningless when tested alone, requires a larger system
- Audio lacks pinpoint accuracy in terms of building a 360-degree soundstage, which is common for upfiring speakers
Takeaway: The Monitor XT90 height speakers bring immersive 3D sound to the home without costing too much or making setup too complicated. They are a good option for anyone wanting more control over building their own home theater sound system.

KEF
Q4 Meta
499
/
Released
2024
The slender and sleek Q4 Meta is a highly versatile on-wall speaker that can be used as left, centre, and right (LCR) speaker, or as a surround speaker. Featuring a 5.25" 12th generation Uni-Q driver array with MAT™, the HiFi speaker delivers an expansive, immersive soundscape without taking up valuable floor space.
KEF's signature Uni-Q technology places the tweeter in the center of the woofer to create a single point source for sound, while their Metamaterial Absorption Technology absorbs 99% of unwanted sound from the rear of the driver. Their Music Integrity Engine corrects timing errors in the speaker crossover, and their Shadow Flare technology reduces diffraction for improved detail and clarity in sound reproduction.
Expand Details
Our Summary
Product Strengths
- The reviewer liked the Q4 so much that they bought two more
- The reviewer was impressed with the Q4s
- Rated down to 42 Hertz in-room response, the port provides a fuller bodied sound
- It can be used as a LCR (left, center, right) speaker, making it versatile for different channels
- The driver is very much the same as in the KEF R11s as well, promising timbre matching will be no problem
Product Considerations
- The reviewer wishes the port was underneath, so it was more hidden when hanging it vertically
- The reviewer wishes KEF would make a custom grill to match the R11s
Takeaway: The Q4 sounds really good and is impressive as a center channel, performing bigger than it looks. Its ability to be mounted and act as different channels allows it to be a very versatile piece of equipment.
