"The Trenner & Friedl RA loudspeakers. All we can say is wow." – Dave Clark, Positive Feedback

The original, standard-setting member of our new, Natural Fidelity Line of high-end loudspeakers: Design distilled to the essentials – Technology and Hand-Craftsmanship in perfect harmony.

Ra's stoic exterior unleashes a musicality that simply doesn't let go – the eye calms, the ear rejoices. Ra plays with power and dynamics – if desired, even at original volume levels. 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.

Technical details may be found in our Datasheet at the end of the photo array.
