What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- Designed by Siegfried Linkwitz, a loudspeaker engineer.
- Soundstage is a key selling feature, often described as wide and open.
- Takes well to equalization because of the good directivity index.
- Design allows placement in a home environment without requiring extensive acoustic treatments.
Product Considerations
- Requires a four-channel amplifier and a MiniDSP (or equivalent) for active crossover and equalization.
- Bass response may require a subwoofer for those wanting more low-end.
- Some reviewers found the default tonality via the MiniDSP settings not to their liking and requiring adjustment.
- DIY speaker, so it takes time and some skills to build, unless purchased pre-made.
Takeaway: The LXmini is a unique speaker that gives a great soundstage. For those looking for speakers that sound musical and complement a room, these could be worth building.

Manufacturer details
- Frequency Range: 45 Hz to 20 kHz
- Driver Configuration: 2-way loudspeaker
- Drivers: 2-Woofers (5 inch), 2-Fullrange drivers
- Amplifier Power Requirements: 50W to 200W (4 channels required)
- Low End Roll-off: 12 dB/octave
The LXmini is a 2-way loudspeaker, which can be built DIY from a Kit for around $800, including miniDSP 2x4HD equalizer/crossover. Additionally, 4 power amplifiers in the 50 W to 200 W range are needed. The speaker's frequency range extends from 45 Hz to 20 kHz.
The horizontal and vertical off-axis frequency response, which is heard via the room, is spectrally neutral. Thus, listening off-axis merely changes the viewing angle to the phantom acoustic scene rendered by the seemingly absent loudspeakers.
Physics limits the maximum sound level output from a 5 inch woofer below 150 Hz. A gradual, 12 dB/octave low end roll-off provides satisfactory bass extension below 50 Hz. For LXmini+2 I added separate subwoofers for bass extension to 25 Hz. If you plan to upgrade in the future from LXmini to LXmini+2, then use the miniDSP 4x10HD for LXmini.

Our take on the brand
Look inside the brand
Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
LINKWITZ speakers take the room out of the equation. No room treatment necessary, no DSP "room correction" necessary (as demoed on AXPONA2025). This is possible because these are full range dipoles (not only open baffle speakers , which end being dipoles at around 1-2kHz) . This benign radiation pattern allows a wide "sweet area" to enjoy a believable soundstage, that can actually achieve a depth of 20ft and more. The LINKWITZ dipole bass regularly provokes jaw drops. You can feel the drum stroke in your chest. Dry, powerful and un-boomy due to its unique radiation pattern. Physics at play! This kind of top performance can only be achieved as an active setup. We optimized our fully analog signal processor to the latest phase coherent, cascaded architecture.
What's your approach to customer support?
Fortunately, since more than 12 yrs in business, we see very few issues, as everything is thoroughly tested before shipping. If any issues arise our customers email us for further procedure. Our service for turnkey systems includes set-up assistance for optimal positioning / toe in (video call)
What are your favorite tracks for showcasing the strength of your products?
Two aspects:
Demo, how authentic a spatial setting of musicians & their music can be experienced at home. This can be judged best, when you know, the situation at the recording venue:
- Come On In My Kitchen by Carmen Gomez Inc, (Label SoundLiaison)
- Equinox by Markus Schwartz & Lakou Brooklyn (Label Soundkeeper Recordings)
- The reference recording in DSD256, done in minimal mic technique from this event is a milestone in authenticity, believability and naturalness. See this free download link.
Demo of dynamic and chest-hammering bass drums with dipole subs:
- Liberian Girl (Michael Jackson)
- Bass and drum Intro (Nils Lofgren)
- Game of Love (Daft Punk)
What other products pair best with yours?
We appreciate every source , that provides a good analog signal to feed our PowerBoxes. This can be reel-to-reel tape machines, vinyl or very good DACs. We prefer, if the signal is kept with least interference/filtering/altering.
Of course, everything starts with the proper recording technique and equipment. We appreciate the outstanding work of labels like e.g. SoundLiaision, Soundkeeper Recordings, Outermarker records, Cohearent records, selected ones from EVO sound, and some older OnePoint recordings from DENON.

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
Our summary
Product Strengths
- Fit and finish plus performance that is a bargain for around $3k/pair
- Gelcore cabinet construction minimizes unwanted sound energy from resonance and vibrations
- A tweeter that is hermetically sealed and mechanically isolated (floating) from the baffle provides lower distortion
- Size, weight, and richness of tone belies their size, with a wider baffle to each loudspeaker pointing at you
- A mild sound throws emphasis back to the midrange that in itself seems almost holographic, as well as deeply insightful in a gentle but revealing manner
Product Considerations
- A medium to large size room is required to shine, otherwise the bass will dominate
- Flaws in poor recordings can be revealed due to their detail and accuracy—warts and all performance
- The top-end is a little soft and gentle—classic BBC like—which may require amps with some zing to compensate
- Listeners seeking absolute detail or transparency might not be satisfied because of Q Acoustics' house sound that massages treble and plumps up bass and lower mid
- They don't go sub-40Hz deep, frequency response is rated at 42 Hz – 30 kHz (-6dB)
Takeaway: The Q Acoustics Concept 50 offers excellent value with its blend of innovative design and high-quality sound, making it a great choice for enjoying music with a sense of depth and engagement. The Concept 50s are easy to listen to and fun.

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.
