Our summary
Product Strengths
- Integrated technology allows direct high-resolution listening without extra devices
- The speaker uses the same Pascal Class D amplification and processing technology from Dynaudio's Pro line Core series
- Discrete amplification channel per driver: 110 watts for the tweeter and 280 watts for the woofer
- Dirac Live room correction is available, which can tune some of the annoying sounds of a garage, for example, using the soft dome tweeter
Product Considerations
- Running a digital coaxial cable from one speaker to the next results in the signal being sent at 24-96 kilohertz, which is a lower quality than what the master speaker receives (24-192)
- There is no HDMI arc or e-arc connection
- Drilling holes may be required to attach the speaker to stands
- Setting up the speaker with the app is not as quick or seamless as Bluesound
- A microphone is required to do Dirac room calibration
Comparisons (according to reviewers)
- Vs PSB Alpha IQs: Plays louder with a higher level of amplification
- Vs Dynaudio Core 7: The Core 7 has more power and a slightly better tweeter and woofer, but is not as aesthetically pleasing and needs a Bluesound Node
- Vs Dynaudio Evoke: It is similar to an Evoke speaker, but with a bigger woofer
Takeaway: The Focus recMsY5ljWopDD7UU is a sophisticated wireless speaker that pulls technology from Dynaudio's Pro line and features Dirac room calibration. It is ideal for someone looking for high-resolution listening without extra devices and who values sophisticated sound and aesthetics.

- Immense potential, described to be a top shelf product

- The image was a little high

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- Delivers greater tightness and precision from the crossover point on down
- Delivers an extended high-frequency range, with greater detail and more openness without harshness
- Stereo imaging is amongst the best
- Has no sweet 'spot', which allows the engineer, producer, and client a fairly similar listening experience
- Has a smoothly extended bass response that reveals what is really going on in that elusive bottom octave
Product Considerations
- The BM-15As may be overkill for a smaller mixing environment and better suited for larger rooms
- High end is as clean and accurate as the BM-12s, but the mids were a little lacking
- While they have a slightly forward characteristic, it doesn't get in the way of accurate monitoring
Comparisons (according to reviewers)
- Vs Dynaudio BM-12 MK3s—BM-15A has more bass extension and pure raw SPL power
- Vs Dynaudio BM-12 MK3s—BM-12 MK3s have more detail in the mid-range
- Vs Dynaudio BM-12 MK3s—BM-15A are far louder and put out substantially larger amount of energy in the bass and subs
- Vs Genelec, Focal, Neumann, and Event—the Dynaudio BM series are in the same class as these monitors
Takeaway: The BM15A is a speaker that gives great stereo imaging with a wide frequency range, and produces an accurate sound which is nice to listen to for long periods. Full-range monitoring in a smaller studio is possible with these speakers.

Video review
Our take on the brand
Our Summary
Product Strengths
- Remarkable sound power and early directivity indexes make it a true point source speaker.
- Special sound quality for the price offers a level of performance not typically found in speakers at this price point.
- Very good neutrality is present when the speaker is turned off axis.
- It is a very versatile speaker to drive.
- The midrange presentation is very dead center and coherent.
Product Considerations
- The bass does not reach as low as some listeners might prefer.
- The speaker can get bright at times.
- Care should be taken to place it not directly on axis, because when placed directly on axis, it is no longer a neutral speaker.
- There's no stand included in the package.
- It is made in China, and construction can be suspect.
Comparisons (according to reviewers)
- Vs PureAudioProject Duet 15, the SourcePoint 10 is more precise and focused, while the PureAudioProject has a bigger soundstage.
- Vs Fleetwood Deville SQ, they sounded more alike than different when in action, but SourcePoint was more extended from top to bottom and brought more lively dynamics and impact.
- Vs Klipsch Heresy IV, the SourcePoint 10 is the superior speaker in every way from build to sound, with more refinement and smoothness, and it seems just as dynamic as the Klipsch.
- Vs Dynaudio Special 40s, the SourcePoint 10 sounds much bigger, more dynamic, has much better bass, and fills a room with ease.
- Vs KEF LS50 META, the LS50 sounds smaller, leaner, and not as special in the vocal region.
Takeaway:
The SourcePoint is a speaker with a neutral sound that originates from a single point, and it has remarkable early directivity indexes. It is a speaker that offers very good performance for the money, but careful attention needs to be paid to its placement in the room.
Video review
Our take on the brand
Our Summary
Product Strengths
- Solidly built with an inert cabinet, contributing to overall performance
- Crazy linear/neutral sound from about 100Hz upwards
- The beryllium tweeter provides nuanced, airy, and extended highs with a hint of shimmer for realistic metallic instruments
- It creates a three-dimensional soundstage, making the speakers disappear sonically
Product Considerations
- It does not have a great deal of bass on its own and may require a subwoofer for full-range playback, starting its roll-off at around 100Hz
- While placement is flexible, a solid amplifier is required
- The styling might be an acquired taste and could be considered overcomplicated by some
- The high gloss finishes may not appear different from less expensive speakers, making it harder to justify the luxury price tag
Comparisons (according to reviewers)
- Vs Bowers & Wilkins 805 D4: The S4B is more neutral/accurate, while the 805 D4 adds bass and treble energy
- Vs Focal Canta No. 1: The S4B outperforms the Canta No. 1, which has chestiness in its bass and midrange due to its cabinet
- Vs Revel Studio 2: The S4B reminded the reviewer of the Revel Studio 2, though the Revels had more bass
- Vs Focal Diablo Utopia: The Perlisten are a great alternative if the Utopias are outside of your reach and are a more neutral and less bright speaker
- Vs EgglestonWorks Nico Evo: The EgglestonWorks presentation is a little more mid-forward and less 3D than the Perlisten
Takeaway: The Perlisten S4b is a high-performing speaker that offers excellent clarity and a neutral sound, making it a great choice for audiophiles and home cinema enthusiasts alike. The speaker's ability to create a detailed and immersive soundstage can bring music and movies to life.
