Pros
Exceptionally fast, low-distortion impulse response delivers clean transients, clearly separated musical lines, and highly intelligible vocals.
Produces a spacious, precise, three-dimensional soundstage with strong image focus, presence, and fine detail.
Extensive onboard room, treble, bass, nearfield, and input adjustments support tailored performance in different rooms and installations.
Superbly finished, solid active construction with dedicated amplification for each driver.
Cons
Bass is clean and tight but may lack warmth, punch, and the pressure of larger-scale alternatives.
Precise toe-in is critical; small positioning changes can substantially alter imaging.
The silky, non-fatiguing treble can sound slightly restrained without adjustment.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 86/100
The S1 is praised for an unusually clean, coherent and highly resolved presentation, with exceptionally intelligible vocals and little sense of blur. Its standout is transient precision, though the leaner low end, restrained treble balance and placement sensitivity mean it will suit careful setup and listeners who favour accuracy over overt warmth or slam.
Bass
84/100
Alpha Audio found the bass clean, tight and occasionally capable of very deep thumps. However, it does not consistently build the expected pressure, with some missing warmth, punch and deep-bass extension noted.
Mid
87/100
Vocals are described as exceptionally intelligible, while individual musical lines remain easy to follow in complex material. Although measurements suggested a somewhat recessed midrange, the reviewer did not hear the speaker as veiled; instead, it came across as calm and composed.
Treble
86/100
The treble is described as silky smooth and remains free of harshness or unpleasant edge. The reviewer would nevertheless have liked slightly more top-end energy, suggesting a refined rather than overtly airy balance.
Soundstage Imaging
88/100
With a well-recorded track, the S1 produced a magnificent, spacious, clean and accurate presentation. Imaging is notably dependent on setup, however, as even small changes in toe-in can have a drastic effect.
Dynamics
89/100
The S1's driver is singled out for exceptional speed, low distortion and impulse behaviour described as approaching headphone-like immediacy. It tracks transients with impressive ease, though the reviewer still wanted more punch and, at times, deeper low-frequency impact.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
92/100
Alpha Audio calls the S1 superbly finished and superbly solidly built. The active implementation, separate amplification and tuning for each driver, and robust overall execution were also viewed positively.
Value for Money
85/100
No price was supplied, and the review does not directly compare the S1's value with competing speakers. It presents the product as technically distinctive, strongly built and capable, but offers no clear verdict on whether it represents a bargain or premium worth paying.

Manufacturer's Description — Manger
Ultimate choreography
Music is more than a collection of notes, tones and bars - it combines creativity, art and passion in a temporal context. Temporal perfection is the framework of the music - in the original as in the reproduction. The Manger s1 active loudspeakers follow this choreography more consistently than any other loudspeaker and are thus able to reproduce music unadulterated and holistically.
Time of maturity
Faithful reproduction has been the goal of Manger Audio for more than 50 years. All the knowledge, all the experience of research, engineering and craftsmanship over these years are reflected in the Manger s1 sound systems. Their timeless design is an elementary part of the overall construction. The masterfully crafted housing offers the electronics and chassis the working conditions that are crucial for perfect reproduction.
Design and technology in harmony
Their attractive shape cleverly hides the effort and meticulousness that goes into every detail of a Manger s1. An ultra-stable frame inside the loudspeaker prevents sound-damaging resonances from the cabinet walls and standing waves in the interior. The chassis are meticulously embedded in a 1,5" millimeter (!) thick front baffle and each has its own closed compartment. Generously rounded housing edges reduce sound diffraction, optimize the radiation behavior and underline the timeless elegance of these exceptional loudspeakers.
Under the sign of the star - the Manger sound transducer
Achieving top performance means leaving the beaten track and going new ways. Conventional loudspeaker drivers were quickly ruled out for Manger in his search for time-correct reproduction. The development of a sound transducer that does not suffer from the systemic errors of conventional driver in the patented Manger sound transducer. This innovative system is world-wide in the disciplines of time-accurate reproduction and signal fidelity without comparison. A powerful woofer in the Manger s1 seamlessly complements the lowest octaves and offers sufficient reserves to effortlessly fill large rooms with euphonic sound.
Elaborated in every detail
No element of the s1 has been left to chance. As Manger puts it: Even the smallest component is of critical importance as part of a chain that is only as strong as its weakest link. The drivers are not only attached to the cabinet with durable threaded screws and the analogue amplifiers and control electronics are as well. The electronics housing consists of diligently crafted, almost resonance-free aluminum that seamlessly aligns with the loudspeaker enclosure. The cables are fed in through a generous recess at the bottom to avoid bending. The solid base construction of the s1 guarantees the speakers perfect contact with the ground via the innovative and practical Manger cone feet cf1.
Unique in sound, as diverse as life
Thanks to their elegant shape, the Manger s1 fit harmoniously into any ambience, whether classic or modern. In the finish, you decide on the finishing touches. White, gray or black underline the technical note of the speakers - but Manger is also happy to manufacture the cabinets according to your individual color requirements. Benefit from the possibilities that only a highly specialized manufacturer can offer.
