Tweeter and woofer on a single axis — this coaxial two-way system sets the SB-RX50 apart from most loudspeakers of its day. It ranks among the finest models of the Technics RX series, with drivers made of carbon fibre. The layout yields exceptionally precise spatial imaging, exact localisation of voices and instruments, and a harmonious, well-balanced tonal picture.
Sonically, powerful, deep bass, natural mids and finely resolved highs take centre stage. Thanks to their high power handling, the speakers perform confidently and with low distortion at soft and loud levels alike — rock, jazz, pop or classical. Treble and midrange can also be adjusted via high-quality potentiometers.
This pair comes from its first owner and a non-smoking household. Cosmetically it is in very good shape with the original grilles, free of scratches or damage; technically the speakers are in excellent order. Drivers and controls were serviced by authorised audio technicians on the previous owner's behalf around three to four years ago, with the original condition fully preserved. No further accessories are included.
