The cabinet consists of a 21 mm thick frame and 50 mm thick side walls, which are joined to form a kind of monocoque structure using high-frequency hot-pressing. The R1TX is equipped with coaxially arranged tweeters and mid-range drivers with beryllium diaphragms, which together cover the wide frequency range from 250 Hz to 100 kHz. The bass is provided by a woofer with "TLCC cone", a combination of lightweight foamed acrylamide and aramid fibres. The speakers will be available from August in the "Beryl" and "Smaragd" colour versions at a pair price of 135,000 euros. Individual cabinet designs are available on request.
