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.

Alida CSC

Wilson Audio’s first wall‑mount loudspeaker was designed as part of the W.A.T.C.H. (Wilson Audio Theater Comes Home) system. This foundational creation’s sole purpose was be the surround‑sound component of a 5.1 installation while nonetheless offering the frequency response and dynamic contrast to complement Wilson Audio’s large floorstanding main speakers.

Over time, however, it became apparent that the performance of the W.A.T.C.H. Surround speaker was so good that people began using it as a wall‑mounted speaker in two‑channel music systems. Now found in bedrooms, offices, or other locations where space or architecture precludes the use of floorstanding loudspeakers, this need was recognized and the original Alida was born—designed for main‑channel playback while still excelling in multi‑channel surround applications.

Ultimate Emersion

 Captivating multi‑channel audio and cinematic experiences await those who choose surround systems. Alida CSC is ready. Surround‑sound content has come a long way from its infancy in the early 1980s. Dolby Atmos systems now support configurations like 5.1.2 or 7.2.4 (the last number refers to ceiling‑mounted speakers).

Because Alida CSC remains the uncompromising choice for state‑of‑the‑art multi‑channel audio and surround sound, we developed—and now offer—the Alida Ceiling‑Mount option to accommodate the most ambitious Atmos setups.

Alida CSC includes numerous upgrades to the critical elements that sculpt its sound. From the Convergent Synergy Carbon (CSC) tweeter and custom in‑house crossovers to the mounting bracket employing our proprietary V‑Material, Alida CSC delivers the timbral neutrality, dynamic response, soundstage depth, and transparency of floorstanding Wilson Audio speakers—even under the demanding conditions of surface‑mounted applications and Dolby Atmos™ ceiling installations.

Wilson Audio is often considered the quintessential American high-end hi-fi brand, a staple in premium audio dealerships across the country. Many reviewers use Wilson speakers in their own home systems, reflecting their reputation for outstanding dynamics, bass depth, and the ability to reproduce classical music with remarkable realism. Wilson focuses on creating an uncolored sound, aiming to replicate the experience of live, unamplified performances.

Product Strengths

  • The Alida CSC tweeter matches the Alexia V and Mezzo CSC, significantly improving sound.
  • Technical upgrades in the Alida CSC dampen vibrations.
  • Upgrading to Alida CSC from original Alida speakers creates a more cohesive and immersive sound experience.
  • The Alida CSC enhances the reproduction of delicacy, detail, and dynamics in immersive music.

Product Considerations

  • Bolting loudspeakers into one's walls and ceiling can raise anxiety.
  • The Alida CSC is part of a very expensive system upgrade.

Takeaway: Upgrading to Alida CSC speakers can significantly enhance the immersive music listening experience, creating a crystal-clear sphere of sound in the listening room. The improved tweeter and vibration damping contribute to a more detailed and dynamic sound.

Thrax
Sirens

Reviews

Sirens are brought to your attention due to a very recent development in speaker drivers by Purifi Audio. They have addressed and implemented solutions that advance the design of conventional moving coil speakers in multiple areas, leading to an order of magnitude better performance. It was worth our attention, so here we are with our little babies, taking full advantage of these new drivers.

For the Sirens the brief was – shrink the Lyra to bookshelf size and lose nothing! Well we lost 3db sensitivity but the performance gain due to the new driver and our unique new serial crossover takes the Sirens in a league of their own. Phase response linearization presents you with a new tone on many familiar voices. The lack of break up in the cone allows for a gentle slope of the crossover and better blending with our horn.

The zero resonance front baffle not contributing to the sound underlines the drivers unique abilities. Compact cabinet size doesn't limit the low frequency performance of the Sirens keeping the extension the same as on the Lyra via a rear mounted port.

Crossover components used are all premium - foil capacitors and air core inductors potted in polyurethane for vibration free optation and all wired with custom OCC copper wire for undisturbed low level detail and resolution.

The Sirens favor amplifiers with generous power reserves, so the lack of dynamic compression can be exploited in full at realistic sound levels. Yet a flea powered single ended amp will work just as well due to the Sirens virtually flat impedance and phase making them an easy load.

The use of real leather was chosen to complement the softer styling or the speaker accentuating the luxury pedigree of the product. Sirens possess a voice no one can resist, once experienced they enchant the mind and have brought many travelers to the shores of Thrax.

Thrax Audio is distinguished by its use of transformers for volume control instead of traditional potentiometers in their Dionysos preamplifier, and their Spartacus amplifier features a unique two-stage shunt regulated Directly Heated-Triodes push-pull design in pure class-A with no feedback.

Expand Details

Product Strengths

  • The Siren produces a delicately resolved, very detailed, and natural treble range with exceptional expressiveness and subtle dynamic nuance
  • The Siren offers a balanced and natural richness in midrange with much microdetail and growing transparency
  • Once properly set up with spiking, high-end resolution, image depth, and convincing dynamics are achieved
  • The Sirens can be played at almost any volume level within reason, coupled with a smooth frequency response and low distortion
  • The Siren can disappear into the soundstage illusion

Product Considerations

  • One review sample had a miswired tweeter, indicating a potential quality control issue
  • At very high sound levels, the modestly dimensioned bass port began to huff a little, with some limiting a little earlier than the midwoofer did

Comparisons (according to reviewers)

  • The Siren demonstrates much of the pure harmony of a large panel speaker, but with the dynamics of a studio monitor
  • Much of the intimacy heard on Branko Bozic's system comprising conrad-johnson ACT2 series 2 tube amplification with Karan KA M1200 monoblocks driving the magnificent first-gen Avalon Isis speakers was recreated with the Siren, if on a smaller scale

Takeaway: The Thrax Audio Siren is a well-engineered loudspeaker that delivers exceptional sound quality with natural timbre and impressive soundstage capabilities. If high-fidelity music enjoyment with great detail and clarity is desired, the Siren is worth considering.

Our Summary

Product Strengths

  • The aluminum cabinet is cast in one piece, which offers acoustic advantages and looks chic
  • The extruded aluminum yields a seamless, curved cabinet, which minimizes standing waves, reduces diffraction, and distributes and controls reflections
  • Highs are provided by a ribbon tweeter designed by PIEGA, and made by hand at the company's factory
  • It creates an incredibly wide soundstage, always balanced and rich
  • They are big enough to make big sound, but small enough to be suitable for a small apartment

Product Considerations

  • The fit and finish of the small, square, lightweight Connect is basic—in sharp contrast with the stylish, substantial 701 loudspeakers
  • DSP automatically adjusts each speaker's frequency balance according to volume, at a low setting, bass and treble are subtly boosted while, with something closer to party levels, the bass is gently reined in to prevent driver overload
  • The Android version won't 'read the room' and only lets one turn the room correction on and off

Comparisons (according to reviewers)

  • Vs KEF R3 Meta: it gives a cleaner sounding mid-range and better top-end extension
  • Vs Buchardt A700: pairing the speakers to its black box comes with fewer connection hassles
  • Vs KEF LS60 wireless: it draws a wider soundstage, better image in the mids, and offers a more extended top end

Takeaway: The PIEGA Premium recMsY5ljWopDD7UU is a stylish speaker that offers a wide soundstage and a rich listening experience. Its modern design and high-quality build make it a great addition to any contemporary living space.

Sonnet
Acelec Model One
6750
/
Released
Model One is possibly the most transparent conventional loudspeaker available today. Over the last two years, intensive research has been dedicated to exploring new methodologies and materials. These are now incorporated in our latest product range. Model One is a premium loudspeaker, offering absolute performance from the clean lines of its compact cabinet.
Check Amazon
Sonnet Audio is known for their unique R-2R ladder DAC design that splits 24-bit signals into two 12-bit streams processed by separate resistor networks, and their DACs feature volume control through reference voltage adjustment rather than digital potentiometers. Their products, including the Morpheus and Pasithea DACs, use a modular design with upgradeable components and emphasize non-oversampling techniques for natural sound reproduction.
Expand Details

Our Summary

Product Strengths

  • Exceptional cabinet construction minimizes resonances and time-smearing, leading to a 'lifeless' and inert cabinet that avoids ringing
  • Clarity, transparency, and ability to deliver minutely organized and naturally displayed recorded data are strengths, offering a deep look into the soundstage and textural nuance of instruments
  • Excellent imaging and a wide, deep soundstage belie their small size
  • Placement is relatively unfussy, working well even close to walls or in corners
  • High-quality components use a Mundorf AMT tweeter and a Scan-Speak mid-woofer, along with high-quality crossover components

Product Considerations

  • With a sensitivity of 84dB, it may not be ideal for low-powered SET amplifiers
  • While the bass is balanced, the 45Hz low-frequency response might not be sufficient for larger rooms or those who prefer deeper bass
  • The AMT tweeter is highly directional, requiring careful toe-in for optimal treble detail and potentially resulting in a narrower sweet spot
  • Some speakers with aluminum enclosures can miss the mark in musical satisfaction, bringing a certain sterility, though the Acelec does not have that problem

Comparisons (according to reviewers)

  • Compared to the Klipsch RP-600M II, the Acelec Model One presented vocals with starker, clearer sound compared to the Klipsch's 'hazy neon-lit environ'
  • Similar construction to the Magico A1 using hardwood over a thick solid aluminum frame, but the Magico is more expensive
  • Similar to YG Acoustics/Magico, the Acelec design uses aluminum construction for clarity not found in speakers using other cabinet materials
  • Acelec Model One panels come even closer to complete silence than Genelec G Three
  • The Acelec Model One does not quite have the scale and sweep of larger speakers such as the DeVORE FIDELITY Super Nines, Dali Oberon 7, and DeVORE FIDELITY 0/96

Takeaway: The Acelec Model One offers incredibly detailed and accurate sound with minimal cabinet resonance, making for an immersive listening experience in small to medium-sized rooms. It could be a great option for those who want a transparent speaker that reveals every nuance of their music.

Our Summary

Product Strengths

  • Fast, precise, and airy sound reproduction
  • Superb clarity and control due to materials and construction
  • Near characterless clarity and uncolored coherence, allowing deep listening into music
  • Scary-good imaging and expansive soundstaging
  • Produces a giant, stunning soundstage with pinpoint imaging

Product Considerations

  • Asking any stand mount speaker to fill a large space is a tall order
  • Requires a muscular amplifier that can comfortably drive low loads
  • Bass is not going to flap trousers, so consider adding a good subwoofer if more is desired
  • Take care not to place the Coax 411 Gen 2 too close to walls or corners, otherwise the bass might become a wee bit heavy
  • One tiny criticism–the removable grilles of the Piega Coax 411 loudspeakers are a little bit of a pain to remove

Comparisons (according to reviewers)

  • Vs Perlisten R7t Tower Speakers: The Perlistens are better suited for a larger room, while the 411s are better for smaller rooms
  • Vs Klipsch Cornwall IV floorstanders: Very different beasts–far bigger and much more sensitive–yet similar in price terms
  • Vs Gershman Acoustics Studio XdB: The Gershmans are warm and embracing, while the Piega Coax 411 is precise and filled with inner detail

Takeaway: The Piega Coax Gen2 411 speakers offer detailed and uncolored sound, letting someone get lost in their music. They are well-built and stylish, making them a great option for someone who wants both great sound and a modern look.

2021
A brand new and innovative midrange driver entirely developed and manufactured in-house brings the A25-M even closer to absolute perfection. Imagine hearing sound as naturally as in real life. The speakers disappear, you trust what you hear and let your ears work with total confidence. That's what you get with the A25-M!
Check Amazon
PSI Audio is a Swiss hifi brand that builds all their speakers and acoustic devices without using DSP, focusing instead on pure analog technology to deliver accurate sound reproduction. Their standout product is the AVAA C20, a revolutionary active bass trap that eliminates low-frequency noise by creating a "black hole" effect for resonant frequencies, requiring much less space than traditional acoustic treatments while being effective across diverse environments from recording studios to subway stations.
Expand Details

Our Summary

Product Strengths

  • All three of the A25 speaker drivers are designed and handmade in-house in Switzerland to ensure low distortion, high precision, and the finest quality control
  • Every A25 is sonically identical, meaning any two of the same model at any point in their production history will be a matched pair
  • The A25M offers higher SPL at lower distortion
  • Initial listening tests were very favorable, and the first things that stood out were the tight and controlled low end and super precise stereo imaging, leading to a huge sense of depth and space
  • Mixes translated incredibly well to other systems, and when using them for mastering, the bass end was spot on, and the highs were incredibly detailed but not at all hyped or fatiguing

Product Considerations

  • The A25Ms are very heavy, at 28.4kg each, and have the kind of proportions that make a one-person lift of such a weight risky
  • The size and weight of the A25Ms mean they probably will not be considered for nearfield duties by the majority of potential users
  • The overall tonal balance is a little prominent in the upper-mid band, and this sometimes adds a slight edge to some mix elements
  • If considering a move to mid-field monitoring, room acoustics should probably be considered at the same time
  • Enclosure color is an acquired taste

Comparisons (according to reviewers)

  • Vs ATC SCM45s, the ATCs just had that extra tiny level of detail in the mids—it comes down to personal choice

Takeaway: The A25M is genuinely revealing monitors that can provide great insight into the components of a mix and how they fit together. These are spectacular monitors with a tight, controlled low end and super precise stereo imaging, making them an excellent mid-field monitor for mixing and mastering.
