Soulsonic has now two models which are different in the principal and looks, but when it comes to sound they are similar if used in rooms they are meant for.
Both models have great transparency capable of high SPLs with no apparent distortions. IMPACT is meant for smaller rooms, where the big brother could be just to big. Also the IMPACT has slightly more midrange presence (more forward sounding) than IMPULSE that can be a really great experience . It can be listened from the nearfied position with great results.
Perhaps my 20.1s are somewhat more precise in the lower midrange area, but also more lean and less dynamic. This lack of dynamics with 20.1 is very audible, and this pulls you away from creating a life like presentation. Here the Soulsonics are at their best.
They beat my 20.1 at low and high listening levels dynamics by far, also the bass slam is more then awesome.
I think that they can bridge the gap between planars and dynamic speakers more than good and show the best from both designs
The Impulse and Impact sound very airy in the natural sense, tonally and harmonically correct, with great bass slam and extension and...better image specificity than my 20.1.
Among other virtues, the piano has more weight in the critical presence areas, without sounding annoying or distorted. Capable of very high sound levels, provided they are sufficiently away from the back wall, sometimes they remind me of horns (dynamically) without horn colorations. They are way more sensitive than my Maggies and are overall just incredibly involving in the musical sense.
These are some things which are obvious on first listen..
