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

  • The Asylab C6B offers exceptional value, rivaling and outperforming speakers costing two to five times as much
  • The speaker provides a wide soundstage with precise imaging, maintaining focus even when toed out
  • Neutral tonality suitable for various music genres, including Norah Jones, Michael Jackson, Dire Straits, rock, jazz, and rap
  • Consistent horizontal radiation pattern with excellent depth layering
  • Smooth frequency response allows for easy EQ adjustments to tailor sound to personal preferences

Product Considerations

  • An amplifier capable of handling a 4-ohm load is required, with at least 100W or more recommended
  • Limited SPL output capability, especially in the mid-bass, may require a subwoofer for extended low-frequency content
  • The matte finish on the cabinet can be difficult to clean and may attract dust
  • Bass response rolls off around 50 Hz in-room

Comparisons (according to reviewers)

  • Vs Audio Physic Fidelia, the C6B offers a little more air in female vocals and cymbals, while the Fidelia has slightly more meat in the lower midrange
  • Vs KEF Conerto Q Meta, the C6B sounds brighter and more detailed than the KEF Conerto Q Meta, which is described as sounding darker
  • Vs Revel F35, the C6B has less intense high frequencies and comparable bass intensity

Takeaway: The Asylab C6B provides game-changing performance for its price point and will enhance the music listening experience. It is an exceptional value.

Brand highlights

We analyzed reviewers' thoughts of the brand's entire lineup—not just this product—and what stands out most is the following:

Every model pairs a 1 inch dome tweeter with a deep waveguide and a 1.1 kHz crossover, which lowers distortion in a compact cabinet. The C6B is the entry model and suits a small room. The F6B in the middle swaps in an SB Acoustics fiber cone woofer and an aluminum tweeter at the same size. The A6B at the top adds a Purifi woofer and dual passive radiators, so bass reaches 38 Hz at the 6 dB point and it plays louder in a bigger room.

  • Start here. A first buyer with a small room and under $500 to spend should take the C6B, which has the full waveguide design and bass to 50 Hz.
  • Sweet spot. The F6B suits a listener who wants an SB Acoustics driver and the same 50 Hz bass reach as the C6B while paying well under the A6B bracket.
  • All in. The A6B costs well above the F6B and is a bigger bass take on the same design, giving a large room buyer deeper bass and 105 dB peaks from its added bass drivers.

Founding Year

Our take on the brand

AsciLab is a South Korean speaker brand from Seoul, launched by a company with nearly 20 years in room acoustics. Its two-way designs cross over at 1 kHz, a point rare in two-way speakers, using a deep proprietary waveguide to load the tweeter and a steep crossover filter. Designs are developed with finite element analysis and measured on a Klippel NFS system. The range covers passive and active models, including towers and cardioid designs. The compact C6B uses a ceramic and aluminum driver and suits small rooms.

Product Strengths

  • Clear, solid, and refined sound quality
  • Conveniently compact and discreet, fitting easily into various spaces
  • Feature an AMT-1 Air-Motion Transformer tweeter, which enhances clarity and imaging
  • Snappy and agile bass for their size
  • Feature every possible modern connection and streaming capability

Product Considerations

  • Need a stout power amp to sing
  • Lack dynamic variation and punch, making them less musically engaging to some reviewers
  • Bass does not reach very deep, so a subwoofer may be needed for those who love bass
  • Some reviewers experienced frustrating initial setup with the Piega Control app
  • Some off-axis response issues

Comparisons (according to reviewers)

  • Vs KEF LS50 Meta: KEF LS50 Meta offer more musicality, dynamic variation, and transparency
  • Vs Sonos Era 100: Ace 30 is able to play significantly louder and clearer, and with three to four times more dynamic punch

Takeaway: The Piega Ace 30 are compact and sleek speakers that offer a clear and refined sound, fitting easily into any room, or even function as left and right channels in a compact main stereo setup. If quality sound in a small package is desired, these could be a great fit.

Reviews
Monitor Audio builds its speakers around metal drivers, C-CAM cones and domes of ceramic-coated aluminum and magnesium that are light and rigid. The British company, established in 1972, adds Rigid Surface Technology to many cones for extra stiffness and lower distortion. Reviewers hear a lively, detailed sound that stays smooth over long sessions. The hifi range climbs from Bronze through Silver and Gold to Platinum, and Stereophile rated the Gold 300 6G and Platinum 300 3G Class A. The SoundFrame models mount on or inside a wall instead of on a stand.

Product Strengths

  • Intricately detailed, articulate, and powerful sound across the soundstage
  • Astonishing build quality with robust and weighty die-cast aluminium enclosures and a luxurious finish
  • The Apex system delivers audiophile standard sound quality without making huge demands on living space
  • The inert enclosures enable the Apex to deliver an astonishingly fast and detailed sound
  • High frequencies are smooth, speech is clear, and the rear soundstage is expansive

Product Considerations

  • Expensive compared to normal compact systems
  • The AW12 subwoofer is quite heavy despite its compact dimensions

Comparisons (according to reviewers)

  • Apex uses the same tech as Monitor Audio's Silver RX range, but it is 'distilled' down to fit a more compact cabinet size
  • Apex is in a different league than other satellite systems, offering a level of sound quality not typically associated with satellite speakers

Takeaway: The Apex system offers detailed and powerful sound, with an astonishing build quality. It is a great choice for those seeking audiophile-level sound in a compact and stylish package.

DALI
Fazon SAT

Reviews

The DALI FAZON SAT is an elegant and stylish satellite speaker in die-cast aluminium. Its compact size makes it a discreet solution for any stereo, surround sound and TV setup.Die-Cast AluminiumThe organic lines of the die-cast aluminium enclosure combined with enhanced structural integrity, reduced vibration and non-parallel surfaces, are all key elements in the pure, musical tone.Wood Fibre ConesBased on the MENTOR and IKON series, low-loss FAZON series drivers feature low-mass paper cones with wood fibre reinforcement.Curved DesignThe curved lines of FAZON series cabinets eliminate reflections and standing waves.Secure TerminalsEvery speaker in the FAZON series features easy-to-use push button terminals for a secure connection that won't loosen over time.

DALI's idea is wide dispersion, with speakers designed to spread sound evenly across the whole listening area. The Danish company, founded in 1983, makes its own drivers in-house, including its wood fiber cones, and uses its patented SMC (Soft Magnetic Compound) material to lower distortion. Many models pair a soft dome with a ribbon tweeter in a hybrid module. The Oberon 1 C is an active wireless speaker that needs no separate amplifier, and the range climbs through Rubikore and Epikore to the Kore flagship.

Product Strengths

  • The DALI Fazon Sat has a curved chassis made from dense cast aluminum that does not resonate
  • The DALI Fazon Sat has a locking gimbaled mount to point the speaker, and a knurled knob to lock the speaker into position
  • The DALI Fazon Sat has a magnetic grille with no visible fasteners
  • The DALI Fazon Sat has a simultaneously techy and elegant look
  • The DALI Fazon Sat assembles fairly easily, whether wall-mounted or used on the stand

Product Considerations

  • The tiny screw terminals on the Fazon Sat for the speaker cables proved a little cumbersome, and limit the use of thin cables
  • Although the Fazon Sat's bass response is rated to 86 Hz, its 4 1?2-inch woofer cannot deliver much volume at that frequency without distorting
  • A high crossover point is needed to reduce upper bass distortion with the Fazon Sat

Takeaway: The DALI Fazon Sat speakers have great build quality and are easy to mount. They are sleek and will look good in your home.
