The SoundSpace Systems Pirol speakers experience

Among the favorite moments of the Munich High-End Audio Show, 2019 was a visit to the SoundSpace Systems listening booth. It was great to see Michael Plessmann in action playing all sort of music while avoiding any of the typical audiophile music selection cliche. The SoundSpace Systems Aidoni flagship speakers were showing their grand mojo and regardless of non-optimal room conditions, the sound was engaging, dynamic and effortless. 

There is something very different about the SoundSpace Systems speakers and I’ve wanted to know more. Michael explained the complex inner structure and implementation of proprietary materials. He invited me to experience hands-on the smaller Pirol to get a bit more clearer idea about the complete line before digging deeper into the Aidoni’s musical universe.


Pirol is a floor standing 3-way loudspeaker incorporating state-of-the-art technology in all dimensions. It is technically and shape-wise designed for perfect harmony and integrity. Its underlying technology effortlessly creates sound pressure levels above 110 dB without any strain or signs of power compression but also does not lose the composure and envelopment of music at 60dBs. This performance is also a result of its foundation – the cabinet. The cabinet is a triple layer composite, centered around a bamboo core that builds up the woofer compartment and also the frame system for the upper frequencies. The inside is a ceramic shell that ensures unwanted resonances. The outer shell can be chosen individually from Piano Black or other colors, up to Leather applications or solid African teak. The entire cabinet is resting either on solid wood or solid bronze for a perfect grounding. 
Pirlo’s high-frequency reproduction comes from a Neodynium driven  AMT with a diaphragm area larger than 6.000 sqmm. It is supported by an adjustable rear ribbon tweeter. The midrange is an open baffle design. An exponential paper cone driver which goes all the way down to 100 Hz with ease. The efficiency of this passive section rates at 97 dB/W/m. The crossover is a 1st order design. The low frequencies are recreated from two 12 inch carbon fiber drivers per channel in a closed chamber. They are set up for impulse compensation and are driven by an integrated 500 W class D amplifier. The DSP based low pass is adjustable and also first order. It matches the phase linearity of the overall crossover topology seamlessly. 
The final touch in terms of perfect sound reproduction is coming from Pirol’s internal wiring. Every cable connection is individually designed and the geometry is handwoven in Germany either in solid core copper or silver labeling depending on the chosen model.
The overall appearance is shaped to avoid any standing waves and follows strictly Feng Shui principles and applies the Golden Ratio. The Golden Ratio can be found in nature, galaxies, artwork, architecture, literature, and many other areas. Leonardo Da Vinci, for example, perfected its use in every single painting he did. It is the secret to aesthetics. Feng Shui is concerned with order, balance and the harmony of heaven and earth. Micahel feels how the combination of both leads back to the magic of music that to enhance one’s life by bringing it into harmony and balance with its surroundings.


From Einstürzende Neubauten to Bruckner symphonies. Over two days there was enough time to go through the wide selection of music and discover the Priol qualities. As exhibited at the Munich High-End Audio Show 2019, Michael is not afraid to play loud and more than on a few occasions we went crazy with volume. Pirol’s rigid internal structure and ceramic shell is surely a key point of taming the enormous energy while not killing the music. It’s too easy to rip out the music’s rawness, but Pirol’s well-thought innards are properly acoustically balanced. It’s not exactly easy to achieve a level of acoustical control where no frequency is having their forte. That is only one quest with the speakers’ design. The biggest challenge is getting the timbre, tone and color right. While some speakers’ design allows the thunderous rendition of the music, they’re too often sound like a pro-audio system; shouting and nervously delivering the sonic content. It takes a lot of sweat and blood to get any speaker to the real high-end audio plane, where high-end stands for the believable converting of the music where little or nothing is lost in the translation. 
Pirol have exhibited an upper plane level of delicacy, transparency, micro and macro details allowing the music to expand with ease into the listening environment without usual constraints. Horizontal and vertical sonic distribution was easily ensured with the latest models of large Mundorf AMT tweeters. 
The same ability and quality are connected with the midrange impact. The airy midrange is a result of the clever implementation of an open baffle design and paper cone driver. This ensures the juxtaposition of feather-like lightness and needed weight, as well as the believability of vocals and acoustical instruments. 
I’m always keen to hear Vlatko Stefanovski And Miroslav Tadic Treta Majka to critically judge the vibrancy of the midrange. Especially with the song “Ne si go prodavaj Koljo”, where Teodosii Spasov plays Kaval, a Bulgarian wooden flute everything becomes instantly evident and put in the proper perspective. Kaval is not the easiest instrument to reproduce. It’s also not simple to present flute’s harmonics and partial tones. Getting the peaks of the flutes and a pitch right demands efforts beyond ordinary and if something is missing the airiness is gone. Then, instead of hearing the unrestrained flow of the air the flute morphs into the Shepherd toy flute rather than a real-world instrument. Not with Pirols! Pirol speakers easily projected the speed, density, and the objective presence.  
There is something fundamentally right in the way Pirol speakers present the essentials of the music. Even with some of the highly coveted upper echelon speakers, I can (sometimes too easily) spot the absence of proper first harmonics foundation. This translates to a subtle, but noticeable telephone  like effect, where the instruments or voices are not projected with the complete timbral accuracy. 
The voice or instruments are still easily recognizable but not with the sense of ultimate believability. The sonic spectrum is never firm, but changes constantly, resulting in higher harmonics of the harmonic series becoming denser. 
If loudspeakers are not able to render this properly the timbre becomes insubstantial and loses its real-world propensities. 
Regardless of the music being played, I was pleasantly surprised with how well did the SoundSpace  Systems Pirol speakers portray the music without changing the core and golden triangle of timbre, tone, and color. For that feature alone, they are worthy of the deeper exploration.


One of the reasons of the listening session was to exhibit the Pirol real-world scenario behavior. Frankly speaking, most of the people that can afford an upper echelon speakers like Pirol will use them in the domestic environment, where the acoustics are not subordinate to the living room. It’s the other way around these days. The speakers are the part of the carefully planned ecosystem and their main raison d’etre is to provide pure music pleasure without taking too much self-presence. 
This brings us to another factor that cannot be neglected nowadays; the importance of aesthetics. The days of plain simple looking speakers are gone. Music lovers and audiophiles want to have something extraordinary, especially with the given price tags. This calls for special materials, finishes, veneers and proprietary materials. 
SoundSpace Systems Pirol speakers are far from looking ordinary or trying to be just another loudspeaker. Everything is in its place and all particularities have their righteous spot. This is due to the extended implementation of Feng Shui and Golden Ratio principles that are evident instantly even with the first eyes glance.
At my initial encounter with Pirol speakers in the beautiful light veneer, I’ve just set down and enjoyed their looks. My mind was trying to pin down the design cues, but I’ve quickly realized that my perception and experience was influenced by the Pirol’s intriguing sculptural looks rather than déjà vu loudspeakers lines. That tells a lot about their aura…
With their given high efficiency (97 dB/w/m) Pirol can be easily driven even by the small powered tube amplifier without sacrificing the micro and macro dynamics. The same goes for the rich, focused and heavily weighted bass, that was surprisingly filled enormous open space. 
Seldom I’m satisfied with the implementation of the active bass. On contrary, the Pirol’s DSP application Pirol’s showed a great integration without frequency “black” holes or bumps. 
Every product reflects a person’s focus on what’s important to him/her and for their brand. Michael is an avid music lover, traveler, and concert-goer. Consequently, SoundSpace Systems speakers reflect his passion and dedication for the excellence. He wants that music performance is unaltered, true to the origin and life-like. 
And this exactly how SoundSpace Systems Pirol loudspeakers offer… A no constrained aural enjoyment with a far grander sonic projection than what one would expect from their size.  
I’ve enjoyed two days of listening to the music, digging deeper into the classical repertoire, discussing the high-end audio and what’s important in life. ◯
