Trenner & Friedl Isis

Trenner & Friedl  Isis Austrian speakers. Low use, excellent condition.    "...took my breath away" - John Atkinson, 2013. 
The Flagship of new Natural Fidelity Line of high-end loudspeakers – Design, Technology and Craftsmanship in perfection. Isis can be a brute, grabbing hold and never letting go.  Isis is an aesthete, seducing you with the finest det ails from the emotional depths of the composition. 
Superb resolution and precision, highest fidelity and dynamics, extreme linearity: Isis is no simple transducer – Isis is music. 
The in-house finished tweeter, also deployed in our reference model Duke, utilizing a titanium-nickel-coated diaphragm, in concert with our own proprietary aluminum horn, delivers crystal clear highs. The tractrix-based horn shape is an ideal compromise between efficiency and freedom from distortion. 
Isis is bi-amp ready, with bass and mid-high frequency ranges capable of being powered and controlled separately.
