In direct comparison with the DM40, it raises sonic performance through enhanced clarity, yet still sits below the DM70 and DM80 in technological sophistication and dynamic range.
Dymension DM70
- Positioning: A higher-end speaker geared toward delivering a wide and engaging soundstage for mid to larger rooms.
- Description: Introduces an upgraded driver configuration paired with a more sophisticated crossover network that supports broader frequency control and refined acoustic detail. Relative to the DM60 and DM40, it offers marked improvements in clarity and bass control.

Our summary
Product Strengths
- Bipolar speaker design with drivers on both the front and back creates a spacious, immersive, and room-filling sound experience
- Built-in powered subwoofer with passive radiators delivers deep, textural, and adjustable bass, potentially eliminating the need for separate subwoofers
- Clear midrange, allowing for crystal clear dialogue even during loud scenes
Product Considerations
- Placement is critical due to rear-facing bipolar drivers, requiring sufficient space from the front wall to avoid vague or echoey sound
- Integrated subwoofer placement lacks flexibility, requiring careful balancing of speaker placement and individual subwoofer levels
- Tweeter can become harsh and lose composure at high volumes, potentially requiring treble adjustment via receiver tone controls
- Large size may be problematic for smaller spaces and can visually dominate a room
Comparisons (according to reviewers)
- Vs Martin Logan Motion XT-F100: The Martin Logan is better out of the box, but once tweaked, the DM-80s perform as well and have better bass
- Vs Polk R700: The DM-80s can achieve sonic feats the R700 cannot, but the R700 has a better tweeter for those sensitive to high frequencies
- Vs Klipsch RP-8000F Mark II/Cornwall: The DM-80s have a livelier sound and superior bass extension and accuracy, although the Klipsch speakers sound more 'live'
Takeaway: The Dymension DM-80 tower speakers offer a unique and immersive audio experience with powerful bass, making them suitable for both home theater and music enjoyment. With proper setup, the DM-80 can bring that exciting feeling of live sound to one's home.

Our take on the brand
Our summary
Product Strengths
- Powered subwoofer section allows for near chest-slamming bass without a separate subwoofer, especially in smaller spaces
- The DM-30 center channel's built-in 8-inch subwoofer provides a weighty, deep resonance and bass that can be felt directly from the screen, an uncommon feature in center channel speakers
- The DM-70s provide a large, expansive, horizontal soundstage, especially when set to zero dB for the rear tweeter, enhancing atmospheric mixes
- A one-inch aluminum dome tweeter in both the DM-30 and DM-70 delivers crisp, clear, and detailed highs without harsh sibilance
- The system sounds dynamic, fun, and exciting due to the powerful bass and detail, setting it apart from other speakers needing subwoofers
Product Considerations
- The non-removable cloth grill covering the entire speaker may not be aesthetically pleasing to some
- The bipolar radiation pattern of the DM-70s might be too expansive for some setups, potentially blending surround effects too much
- Some might prefer a more direct sound presence than the bipolar design offers, especially with Dolby Atmos surround sound
- An adjustable phase on the back of each speaker would be a welcome addition
- The DM-70s do not quite have the same refinement as some other high-end speakers on the top end
Comparisons (according to reviewers)
- The DM-70 is not as refined as GoldenEar T-66 and Perlisten speakers, but is more dynamic due to its powered subwoofer section
- The DM-30 center channel speaker performs closely in bass and weight to the Perlisten R7C and Focal Utopia center channel speakers, despite being smaller
Takeaway: The Dymension DM-70 and DM-30 speakers are a dynamic and fun-sounding system with impressive bass and clear highs thanks to their powered subwoofers and quality tweeters. This speaker package is a great choice for people who want dynamic speakers that sound great without needing extra subwoofers.

Our take on the brand
The 23 has long been the most popular model in our range – now the Active twenty5.23i builds on that success, combing a combination of weight and refinement in a still-compact floorstanding form.
Already our best-selling model in passive form, the Active 23i adds an active crossover and 2x100W amplification in each speaker to create an elegant floor-standing design even more capable of filling medium-sized rooms with transparent, authentic dynamics and effortlessly extended bass.
With the choice of finishes shared across the Active twenty5i range, it blends unobtrusively into any room: reviewer Chris Kelly said of the passive 23i, 'Pair them with a high-quality amplifier and a good source and you will never regret your purchase,' and that's just what we've done with the Active 23i, building in the amplification for a 'just add source' music solution.
The Active twenty5i series, combined with a preamplifier or any streamer with a volume control, will create a neat, stylish, world-class music system.
Product Strengths
- Impressive control and articulation, handling fast and congested music effortlessly
- Enhances positive qualities of the passive version
- Balances crossover, amplifier and tweeter in a way that avoids harsh or forward sounds
- Achieves more low-end impact compared to the passive version across the volume range
- Offers a wider and more expansive soundstage than its narrow frontage might suggest
Product Considerations
- Bass detail can sometimes be masked by the transmission line and air movement
- Requires a separate source and volume control, not fully self-contained like some active speakers
- The product might be considered expensive compared to other amp-and-speaker combinations
Takeaway: The active twenty5 23i is a good choice for those seeking a peerless solution that maintains hifi credentials and streamlines box-count. It hits harder and sounds sweeter, while providing intriguing system-building possibilities.

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- Build quality and sound exceed expectations for the price
- Beautiful lacquer finish, demonstrating mastery
- Natural, consistent, smooth, slightly warmed, dynamic, and resolving sound
- Very good dynamics and space, allowing for an immersive listening experience with proper positioning and equipment
- Extremely dynamic, natural, full, and versatile sound, particularly for the Jasper 23 Active
Product Considerations
- Stabilizing plinths are too narrow, making the speakers prone to tipping
- Matte finishes can be challenging to keep pristine, requiring regular polishing
- A powerful and high-quality amplifier is necessary to perform at its best, along with a high-end source and audiophile-grade cabling
- Two bass-reflex ports at the back require more distance between the speakers and the rear wall
- The Stereo Hub lacks a LAN jack for the active version (Jasper 23 Active)
Comparisons (according to reviewers)
- Jasper 23's bass focuses on rhythm, pace, dynamics and kick, whereas the Audiovector QR5 provides a subwoofer-type belly massage
- Both the System Audio Legend 60.2 Silverback and Buchardt Audio A700 are larger than the Jasper 23 Active, making placement in a medium-sized room risky
Takeaway: The Jasper 23 series offers beautiful design and great sound. It is well-built, versatile, and a good choice for those who prioritize audio quality.

Our take on the brand
Our Summary
Product Strengths
- Large-scale audio presentation, providing more scale on movies than a similarly priced soundbar
- Fine musical dexterity
- Articulate highs and full-bodied mids
- Precise imaging
- Excellent connection suite, including HDMI ARC and phono input
Product Considerations
- Unfulfilling low end, lacking subwoofer-like grunt
- Sonic character can be a little bright and on the shrill side
- Remote feels a little cheap and response can be slow
- Tower speakers are not the obvious choice for arranging tidily around a flat panel display
- Unrefined when pushed to the limits
Comparisons (according to reviewers)
- Vs Similarly Priced Soundbar—the Magnat Monitor Reference 5A offers a completely different set of attributes due to the drivers' size and delivers a more bold and scaled performance and imaging ability, especially for music
Takeaway: The Magnat Monitor Reference 5A offers impressive music performance, while doubling as a cinema speaker system, and has plenty of connectivity options. If music is a priority and the large speaker aesthetic isn't a problem, these speakers are a good value.

Our take on the brand
Our Summary
Product Strengths
- The Elara LN05A integrates an amplifier, DAC, and Bluetooth receiver, making music listening convenient by removing the need for a separate amplifier
- Features Bluetooth reception with aptX, theoretically capable of transmitting CD-quality music
- Offers rich functionality with digital (optical) and analog (RCA, 3.5mm) inputs, plus a phono stage for turntable connection
- Delivers a slightly warm sound with a hint of sweetness, making it appealing to listeners
- Maintains sound stability and layering even at high volumes, with no signs of audio distortion, indicating a well-configured amplifier
Product Considerations
- Drum sounds lack some punch
- Low-end extension is somewhat lacking, which is likely the LN05A's greatest weakness
- Status display is unclear, making it difficult to know the current volume level or the status of treble and bass adjustments
- Remote control is crucial; without it, the speaker's functionality is severely limited
- The status light uses only three colors with no differentiation; even more frustratingly, there's no way to know the current volume level or the status of treble and bass adjustments
Comparisons (according to reviewers)
- The built-in phono stage of the LN05A offered a slightly denser—more nuanced—sound
- DAC isn't as bright as the Micromega MyDAC, but remains competent
Takeaway: The Triangle Elara LN05A is a convenient and functional speaker that simplifies music listening with its integrated amplifier and multiple input options. Its warm and sweet sound signature makes it an enjoyable musical companion for any home.

Our take on the brand
Our Summary
Product Strengths
- Can play louder and more powerfully than the Fenris A5 and A4 models
- Has a fresh and open sound where no tonal range is left behind, making it easy to listen to
- Has enough power to fill a large living room
- Has a full set of analogue and digital inputs, including a turntable input and HDMI input
Product Considerations
- The sound can become somewhat harsh when the volume is turned up
- Dynamics are limited at higher volumes, with the music becoming a wall of sound
- Requires space and should be positioned away from walls and corners for best bass response
- There is no option to choose whether the active speaker should act as the left or right channel
Comparisons (according to reviewers)
- Compared to Argon Audio Forte A55, the Fenris A55 is less nuanced
- Compared to a Bluetooth table speaker or a Sonos Play:5, the Fenris A55 provides 'bloody real stereo'
Takeaway: The Argon Audio Fenris A55 is a full-grown floorstanding speaker that plays openly and engagingly. Its multiple inputs and powerful sound can emphasize that music is taken seriously.
