Trenner&Friedl SUN Bookshelf Loudspeakers 

Sun, the most compact of our loudspeakers, has many things in common with its big brother Ra: Both are designed to approximate the proportions of the golden section, and like Ra, Sun relies on a coaxial driver for sound reproduction. In the high-frequency region, a 2.54 mm silk-dome tweeter works its magic, while the mid-bass cone is constructed with black-anodized aluminum and, with its 12cm diameter, delivers bass that is nearly as deep as RA—even though our baby naturally does not play as loud in this range as the big brother… 

Sun does not interpret music, rather, he reproduces it: neutral, precise, and wonderfully coherent. 

With its coaxial construction, Sun is in the position to perfectly depict the room and space of the recorded event. 

Placement also raises no problems: Sun can be placed near the back wall and even feels at home in a bookshelf. 

You can easily lift Sun with one hand, but don’t be fooled by its compact size, as it delivers serious musical weight. 

Just as a small point in the heavens illuminates the entire day, Sun fills the room with sound. 

LISTENING ROOM, LIVING ROOM

Many HiFi manufacturers have a problem – they live in a world of listening rooms. Most of us, however, live in living rooms and wish to also hear music there – a conflict that naturally leads to problems. We design our products to be “living room friendly,” they are designed such that they may be placed as close as 10 cm (4”) away from the wall. And while, because of their radiation characteristics, small or narrow loudspeakers are difficult to integrate into a living space, ours deliver more direct radiation to the listening space via their wide front baffle – therefore, you can enjoy superb music, yet continue “living” in the room as before… actually, in fact, better.

What goes in comes back out…

That it is the inner values that count in the end is an often heard and well-proven adage. Loudspeakers from Trenner & 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: 
The 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: 

• Premium Mundorf capacitors, for long life, faster response and balanced tone,
• baked-lacquer coils, flat copper coils with extremely low skin-effect, 
• metal-film resistors for purest reproduction of high-frequencies.

We treat the paper cones of our low-frequency drivers with seven layers of Italian oil varnish, in order to optimize elasticity, damping and stiffness, and reduce cone resonances and distortion. 
Simply stated: only that which you put in comes back out – our loudspeakers should ultimately never get in the way of the music…

LESS IS MORE

So 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. 
Most 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. 
Design 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 music…and, oh, such music!
