SMT moving Forest acoustics into the industrial world


"Scania CV unique SMT S-field laboratory received the prestigious EU assignment to evaluate the next generation electric cars acoustic alerting system."
Thanks to the dense diffuse field combined with tunable Helmholtz modules a non fatigue high resolution seven seat wide sweet spot help the test persons to take decisions in a "New York minute"

A dream sound

Marten showroom

"From Stereo Magazine visit"

"And then comes one of these rare moments, in which you wish every Hi-Fi fan could get to sit down in this armchair for a second to experience the extraordinary listening experience. The sound is perfectly resolved, wide, deep and staggered to the ceiling, and appears entirely detached from the pair of speakers, around 110cm tall, which just stand there almost like spectators to the amazing performance. More than that, the presentation lives and breathes, is light as a feather, yet at the same time physical and substantial, and exudes an extremely appealing high-end aura. The Mahler recording really is first class, but when we played titles with which we were familiar they simply served to underline the class of the system and space. Tiny Islands' inspired adaption of the Taj-Mahal piece "When I Feel The Sea Beneath My Soul" becomes downright hypnotic, the sounds rushing gently yet fleetly like darting fish below the surface, the timing wandering on the narrow ridge of relaxed concentration. Here, too, is the combination of supreme openness and transparency without masking effects, imbuing the music with tangible solidity and a bass as full as it is mobile. As it turns out, the listening room - in which voices appear so present that you hardly have to raise your voice to be understood from the other end of the room - uses diffusers to scatter sound waves rather than absorbers to dampening them. The acoustics are correspondingly lively, and a great deal of effort was necessary to prevent the wandering sounds from blurring the sound: with a number of reversible elements available to fine-tune the character of the room, which can also be used for recordings. This is primarily the workspace of Leif Olofsson, designed so he can really hear what his speakers can do.""


My-Sound Showroom


" I tried over a year in my showroom several acoustical treatments to get the best sound out of our Wilson Audio and Magico speakers. After setting up Matts Odemalm's wings and bubbles there was a complete new quality of music: Balanced, Definition and a soundstage that is so deep that we could not believe it. In high end there is so much "tweak" around which make only small differences and are even not necessary if the acoustic is bad. But SMT is a MUST HAVE!"

How does it sound?
- Even before fine tuning of Q1 position and upstream components, fantastic.
- Bass is extremely clean and detailed. What you hear is bass as it was recorded: flat, clean.
- Excellent imaging: very enveloping and precise in positioning. The large amount of reflected sound from the sides contributes to the illusion of image broadening. The fact that SMT diffusers are similarly effective over the entire spectrum above the transition frequency ensures that the sounds arrive spectrally intact at listener ears. And as we know, precedence effect for localization works best when the spectra of the direct and reflected sound are similar.
- Richness of tone is the best I have heard. Music sounds tonally richer because I can hear more of the timbral nuances (the delay introduced by diffusers gives time to the brain to process overtones which normally are masked by strong transients)
- Neutral room: The room completely disappears to let hear the acoustic of the recording room. The room response to loudspeaker sound is even across frequencies. The room is also neither dead, nor "live": it stores the energy and redirects it over time, with a very regular energy decay curve across frequencies.
- Very even sound response when I walk around the room playing saxophone.



Munich Highend show 2014



Munich Highend show 2014

Statement from Anne Bisson who visited Marten Supreme 2 room at Munich Highend show 2014:
"As I sat in front of the speakers and closed my eyes and the sound was so real I could feel the presence of the musicians near me, It was the same sound that I experienced when I played live with them during the recording. I could really "feel" their presence and it was "disturbing" in a way... and magical too!"
Anne Bisson, Canadian Jazz Pianist, Singer & Composer President of Camilio Records, Audiophile Recordings Canada

Statement from Matthieu Latour, (Nagra), independent sound engineer:
"It is the third High End show in Munich where we did use SMT V-wings in Munich. In those difficult rooms, they helped us a lot to achieve a comfortable listening environment. They increased the level of details as well as they widen the sweet spot, making it possible for more people to enjoy music. The V-wings are very efficient as well as not to invasive in term of esthetical design. Anyone serious about sound reproduction should pay attention to its room acoustics, and I would definitely recommend discussing this matter with Matts. "

S-Wing testimony by LG Ehn




Midas Studios

"Our brand new gobos from Svanå Miljöteknik Ab are truly amazing. They are great for the obvious use of separating sound sources in the studio but also for changing the acoustics in the room and even the sound of instruments. One side of our gobos is absorptive and the other side has a wing diffusor. Turning the diffusor side towards i.e. a drum set makes the whole kit come alive and especially the cymbals very open, clear and sweet sounding, without any harshness. The difference they make is quite staggering!" - Anders Höglund, Midas Studios.

Mårten Designs nya showroom


Marten Designs nya showroom  i centrala Göteborg . Ett level 3 rum på nära 50m2 som på kort tid uppmärksammats över hela världen på grund av den neutrala akustiken samt smakfulla design.

Rummets egenskaper kan sammanfattas som det bästa av två världar:  Frifältets resonansfria återgivning tillsammans med rummets bidrag  av bredbandigt diffuserande  reflexer. 

Den unika akustiken ger också möjligheter för akustiska inspelningar i referens klass.
