At the same time, Ra maintains its delicate spirit, with a sensitivity for the finest nuance. The in-house finished tweeter, also deployed in our reference model Duke, is mounted concentrically at the heart of the 12 woofer, thereby achieving a stable, homogenous tonality, regardless of listening position.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFlying High\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOur high-frequency drivers, designed and developed in-house are something to be proud of. Why? The short answer is:\u003cbr\u003eopen, natural sound, gentle and extremely fine nuances combine with powerful efficiency that can effortlessly reproduce a HiHat at its original live volume, or even more. \u003cbr\u003e\u003cbr\u003eNaturally, not wishing to withhold the exact technical details  here is the long answer:\u003cbr\u003e\u003cbr\u003eIn our high-frequency drivers, a large neodymium ring-magnet drives a TiN (titaniumnitride)-coated 1.75 Titanium diaphragm. Titanium is particularly light, rigid, resilient and temperature and corrosion resistant. The coating is applied via PVD (physical vapor deposition) in a vacuum chamber. \u003cbr\u003e\u003cbr\u003eWe thereby achieve an elasticity 6X greater than Titanium and twice as great as beryillium! TiN is used incidentally for coating tools and weapons. It is highly durable and offers optimal dissipation of heat. \u003cbr\u003e\u003cbr\u003eThis membrane, in combination with a large voice-coil, yields a light and highly durable driver, whose precise reproduction remains linear up to the highest frequencies. \u003cbr\u003e\u003cbr\u003eSound travels through a highly-sophisticated channel into a 1 horn mouth, which in the RA leads directly into the large horn of the coaxial bass driver. In Duke and Isis, the sound is guided by our proprietary tractrix-function horn. This is CNC-milled from solid aluminum billet into a thick-walled, two-piece horn for the purpose of reducing resonances. \u003cbr\u003e\u003cbr\u003eThe result is very, very linear output, even at the highest volumes. Extremely low distortion combines with high output ability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat goes in comes back out\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThat it is the inner values that count in the end is an often heard and well-proven adage. Loudspeakers from Trenner \u0026amp; Friedl distinguish themselves not only in their perfectly finished exterior  the exceptional musicality of our products is built from an equally sophisticated and ingenious inner life: \u003cbr\u003eThe musical signal is received by generously proportioned, rhodium-plated pure copper Cardas terminals, then passed along through Cardas inner-cabling. Our crossovers are carefully hand-constructed from the finest elements: \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePremium Mundorf capacitors, for long life, faster response and balanced tone,\u003c\/li\u003e\n\u003cli\u003ebaked-lacquer coils, flat copper coils with extremely low skin-effect, \u003c\/li\u003e\n\u003cli\u003emetal-film resistors for purest reproduction of high-frequencies.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWe treat the paper cones of our low-frequency drivers with seven layers of Italian oil varnish, in order to optimise elasticity, damping and stiffness, and reduce cone resonances and distortion. \u003cbr\u003eSimply stated: only that which you put in comes back out  our loudspeakers\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLESS IS MORE\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSo many HiFi products are designed with an eye towards  good question, really We so often are confronted with technical-looking monsters that fit into a living room about as well as a production-line assembly robot. \u003c\/p\u003e\n\u003cp\u003eMost listening rooms in this world are living spaces  spaces in which, among other things, we listen to music. We pay attention to this: with their peaceful, modest, yet modern forms, our loudspeakers integrate easily into almost any living room environment. \u003c\/p\u003e\n\u003cp\u003eDesign cannot just be its own sole purpose. It requires a focus. And perhaps our view of HiFi is best compared with a bookcase: stylish, unassuming, yet meaningful, a pleasant part of the room  just that, instead of reaching for something to read, if desired, one can select a piece of musicand, oh, such music!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLIVE LONG AND PROSPER\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePrevious loudspeakers mostly employ surrounds made of rubber or foam, which over time through the evaporation of softeners and because of UV radiation eventually become porous and crumbly. \u003cbr\u003eThe surrounds of many of our drivers are now made out of fabric. This guarantees high stability, extended consistency, and exceptional longevity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eModesty as Ornament\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRa, Pharoah and Isis can be driven wonderfully with lower-power amplifiers, thanks to their high sensitivities of 91-95 dB  therefore, they are the best choice for use in a tube system. \u003cbr\u003eFurthermore, our new line presents a very simple impedance curve to the loudspeakers, thus providing a load that is extremely easy to drive, which can give even more modestly-priced amplifiers wings to achieve their highest performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLISTENING ROOM, LIVING ROOM\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMany HiFi manufacturers have a problem  they live in a world of listening rooms.
