RP-63 is a massive 3-way, four-speaker, bass reflex type construction, whose exceptionally big exhaust has been placed at the back partition wall. A ribbon tweeter is worth mentioning. The remaining speakers are typical: 155mm in diameter, plastic baskets, sandwich – type membrane with cellulose base and a pleat made of glass fiber. The housing is made of MDF board, strengthened at the front with an additional MDF board and with numerous chains inside. The side partition walls converge backwards which eliminates standing waves. High-quality elements have been used in the crossover, e.g. polypropylene capacitors and air coil. The binding posts are double, gold-plated.
