Now new with the Omnes Audio tweeter AMT60 (60.1 angular or 60.2 round). The TB deep-medium toner W6-623 and the Omnes Audio AMT60, harmonize perfectly as a duo. This sonically fascinating production, offers a brilliant listening pleasure on perfect stage. You think you can recognize good high tone, and then you hear the AMT in emotion and discover a whole new level of detail and sovereignty. Equally impressive is the bass rendition of the W6-623 in the TQWT case, punchy and deep without droning. Deep and black when demanded and crisp, precise, these are the clear strengths of the Tiefton Principle TQWT. A successful development to a sensational price-performance ratio.
