Soul Supreme, like all Zu products, is built around the critical human voice (A1, 55Hz, through A6 and all the possible harmonics, to approximately 10kHz). Serving this critical region of tone is Zu’s 5th generation high-output 10” paper-cored nanotech sanctified full-range driver perfectly matched with the Radian 850 based tweeter with it’s nearly 20 pounds of mass also serving as a stressed-member of the cabinet to further remove cabinet talk and electromechanical feedback. This is the same driver we developed for and use on our flagship loudspeaker Dominance and are also using in our other top performing speaker.
Features of this new driver include a maximal motor for expanded dynamic contrast and reduced harmonic distortion, lightweight neutrally-hung voice coil assembly with a paper/Kapton former, linear inline layup of the inner cone for best resolution of detail, diamagnetic shorting assembly for dynamic damping of the moving mass when playing at concert levels, nanotech-impregnated paper cones designed to support wide bandwidth and a machined phase cone with concentric maximal-length sequence diffusion for smooth high frequencies. All this is anchored to a heavy aluminum alloy frame with overbuilt bonded and riveted yoke/magnet/top-plate assembly.
The nano materials and application process reduce weight while increasing strength and propagation velocity without incurring any sacrifices in damping. We lay-up the paper pulp as a core material and essentially infuse a liquid solid matrix on it’s skin. We use nano-processed and nano-engineered materials and key components in the matrix include nanosphere ceramic balloons, nanofiber cristobalite and amorphous fumed silica. Adhesives and binders include melamine, epoxy and nitrocellulose (aircraft dope). First process on the paper core is a matrix of epoxy, nanofiber cristobalite and fumed silica. On this you have a stratum of nitrocellulose and nanospheres. Moving past the lighter, stronger, higher velocity cone you have the Eminence made voice-coil assembly with is combination of paper, Kapton, copper windings and proprietary Eminence adhesives. The center “phase” plug is a carry-over from the research and testing we did with Essence, and gives this driver a more linear management of high frequencies and broader dispersion from the directly-coupled-to-voicecoil inner cone. And as dynamic contrast and to-the-max shove and pop are of primary importance we combine the Soul Supreme with the best tweeter possible, the mentioned Radian 850 based tweeter driver.
Soul Supreme Tech Specs
Third generation ZuGriewe electroacoustic loading
When matched with the proper amp, ZuGriewe driver/cabinet/room loading technology as used in Soul Supreme allows this high-efficiency loudspeaker to deliver quick, deep, articulate bass performance—an attribute rarely achieved in a passive, high-efficiency loudspeaker system of this size. ZuGriewe is an acoustic technology originally developed for high performance competition internal combustion engine exhaust systems, for improving power output through pulse and pressure management, with increased bandwidth, while reducing noise and sound pressure levels over convention.

Amps, Engineering and Design
We love tech’ and engineering, and we love music and sound and sensation. Soul Supreme, like all Zu speakers, is designed by ear first and foremost, using engineering and measures to help isolate and realize solutions for audible improvements. Once we get any loudspeaker sounding sweet we standardize it, including the test and measures procedures and systems used to ensure the highest possible matching and quality. Zu does not engineer around someone’s ideals, implementation of models or engineering conventions.
Tips On Getting Great Sound From Soul Supreme
You should have a 1/4” [6mm] or so gap between the bottom of the loudspeaker and the floor—1/4” is a good place to start, changing the gap height changes the tuning. The gap and the finger ports in the bottom of the cabinet are part of the ZuGriewe box loading technology. They are not ports as used in a bass-reflex design (Helmholtz resonators in all their forms) but the finger ports do need to see the acoustic space of the room. Blocking them turns the Soul Supreme into an interesting “sealed” design.
Soul Supreme has been designed to account for its shorter stature, the 2˚ rake on the obelisk shaped cabinet allows for an expanding soundfield that has the same 2˚ upward declination from level allowing the soundscape to appear larger and taller than you would think. Users can also adjust the feet in the Soul Supreme to tilt the face of the speaker back further tailoring the sound and loudspeakers integration with the room. Soul Supreme ships with both ball-end footers to be used for ward wood floors and long spikes to be used for carpeted floors.
Soul Supreme loudspeakers get 600 hours of factory burn-in, they will sound good right out of the box but will not give you their best for a few days or so depending on temperature and a few other variables. Shipping them in winter months for example seem to cause them to need more time. Other factors effecting how long they take to really open up and sing include how much play they get and what kind of music they see, louder and bigger is better, but you don’t have to go crazy, we take care of the vast majority of it for you. Nevertheless, if at first you find them restrained and a bit conservative, relax, they will come around.
Soul Supreme loudspeakers are very amp sensitive and revealing of upstream gear. And as mentioned, they are also very sensitive to the cold. If you have received, moved or stored Soul Supreme in cold temperatures they will take a week or so to again sound good.
