Micro-Precision – When Sonic Passion Becomes Obsession
Thomas Hoffmann, Mr Hoff, T Hoff, Herr Hoff, The Hoff; call him what you will. When it comes to true audiophile circles everyone will know the name, for Thomas Hoffmann is synonymous with extreme quality audio. For decades this musical genius has dedicated his life to developing some of the worlds best loudspeakers, not only smashing performance barriers with a sonic reproduction quite literally beyond belief, but also developing some of the worlds most impressive materialistic machining methods in pursuit of sheer aural excellence.

When asked about the philosophy of his company Micro-Precision; Mr Hoffmann shrugged and replied In my life I've seen and heard a lot of different 'philosophies'. Most of them appear only on a piece of paper or on a computer screen. For me there is only one philosophy; to find the soul of the music. There is so much more information than first appearances belie. Don't give up, but go on searching for all the details and color in the music. Believe me, there is 'no' end; but closing in on that end is our assignment. To this day this absolute maestro of his art and his staff continue to strive towards attaining such a level of realism and transparency, that you're left listing only to the soul of your music, not left listing to components.

Z-Studio Series – Accuracy And Realism Beyond Astonishing
When it comes to extreme audiophiles you'll nary find one wanting a hammering from their sound. On the contrary there’s an echelon of discerning individuals who desire absolute sound quality in the truest sense of the word. Articulated deep and controlled bass, delectably accurate midrange, and supremely clear highs. Barriers only exist to be shattered, and budget is of little concern. This is the territory of Micro-Precision's Z-Studio range. Developed with every detail absolutely scrutinised in every way; this could be teetering as close to aural perfection as achievable.

Design Ideologies
Micro Precision’s sublime Z-Studio 3.5″ midrange is a high-end midrange speaker with a foam and foil composite cone suitable for automotive aftermarket applications.

Culmination Of Excellence
Micro-Precision’s Z-Studio series’ components represent the culmination of four years of research and development. It’s a true testament to the brand’s dedication to audio excellence. This midrange is part of the Z-Studio range, which offers five exclusive products designed to meet the absolute standards of discerning listeners. The underlying philosophy of all Z-Studio products is the necessity of a stiff and lightweight membrane for accurate sound reproduction.

Magnificent Membranes
Specially crafted for a transparent midrange, the membrane’s design optimizes linearity. This is achieved through a CAD constructed surround geometry, ensuring the best possible sound quality. The total weight of the membrane plus the coil is just 2.7 grams, a design choice that contributes to the speaker’s responsiveness and clarity.

The midrange speakers benefit significantly from the stiffness provided by the innovative resin foam between 6µm Aluminium foils technology, patented in 1935 in Germany. Still in production today, this second-generation technology involves creating a high-tech membrane that is handmade, with an average production of one piece per day. The membrane contains over 80% air within the resin foam. This composition results in the lowest possible weight combined with maximum stiffness and optimal acoustical behavior, thanks to the use of natural materials.

Efficient Space Usage
Despite its small diameter the membrane of the Micro Precision Z-Studio midranges maximises surface area to enhance sound delivery.

Precision Engineering
The Micro Precision Z-Studio midrange basket is assembled with great care and precision. Its production involves 100% CNC machining, ensuring extreme tolerances and eliminating any potential for ringing. The basket has a shallow interior depth, balancing compactness with acoustic capability.

Damping And Venting
Brass damping elements are incorporated into the Z-Studio speakers to improve sound quality. The design also features maximised venting which benefits both the coil and the spider, enhancing overall audio performance.

Integration Of Technologies
Imagining and then realising the integration of these perfect membranes into a perfectly engineered chassis showcases Micro Precision’s dedication to excellence. This achievement is further exemplified by the use of the finest CNC technology in production. The Micro Precision Z-Studio range, through its innovative design and engineering; offers a superior audio experience and demonstrates a commitment to quality and performance that satisfies even the most discerning audiophiles.

Design Features
The rich heritage and knowledge of Thomas Hoffman and his engineering team, together with their ever-increasing technical acumen; is conducive to these components featuring a vast array of impressive design ideologies and latest technological advancements. Some of these include:
– Magnetically inert, aerodynamically transparent alloy basket and housing for very low distortion.
– CNC crafted and machined components.
– Multi-part housing with special acoustic details to optimise overall linearity and frequency response.
– Woofer is optimised for extremely accurate low frequency behavior, as reflected via its low resonance frequency.
– Cone material is resin foam between 6µm Aluminium foils.
– High-energy magnet motor exerts an extremely dense flux over the coil.
– Advanced vented motor and magnet system to eradicate thermal issues.
– Audio viscous damping with special acoustic materials.
– Gold plated push terminals for large cables and corrosion resistance.
