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…
