Functional overview

Specialized design for fixed installation - High-performance Subwoofer.
RS221 is a kind of high-performance subwoofer, can cooperate with RL1/RL0.5/RX212/RX210 loudspeakers, which suitable for various activity centers, gymnasiums, theatres, guildhalls, DISCO PUB, music clubs, performance halls, music bar, highclass KTV and nightclubs. It can be stacked on the ground or hoisted in any direction. It can be hoisted separately or hoisted in the array of two cabinets. The cabinet is designed with bass reflection and can accommodate a single 21-inch long-stroke driver, various designs allow the maximum sound pressure to reach 143.3 dB. The box body is made of high-density birch board, the front side is equipped with hard wire mesh and black PCP (polyurea cabinet protection) paint finish. It has the function of anti-impact and anti-weather. The unit is supported in the middle of the box by a high precision metal material and metal parts, so that the box can be reliably protected. It is equipped with hangers which can be installed horizontally and vertically at multiple angles. It also has rigging which can be supported and suspended at a single point. The connection panel on the back side is embedded and with Speakon NLT4 M connectors. This subwoofer which elaborated by REYN AUDIO has excellent performance in complementary sound and extended frequency band, can effectively improve the dynamic and impact of sound and achieve super-normal level performance; its omnidirectional decentralized design allows it to create various symmetrical and asymmetrical directional working modes, perfectly matching the design of sound field in various activity sites.


  • RS221 is a reflective subwoofer, the concept of design adheres to the highest standard of sound, its excellent transient response and low frequency dynamic response to ensure a real and powerful bass regeneration.
  • The subwoofer use the B&C units which imported from Italy, ensures quality stability and conforms to all kinds of quality.
  • The frequency ranges from 25 Hz to 100 Hz, there is a 21-inch long stroke / 4.5 inch (116 mm) voice coil with a waterproof paper tray and three-ring driving unit. Each driving unit can achieve 3400 watts rated power, the design of magnet structure and double elastic wave can meet the maximum linear stroke.
  • Adpots fashionable beveled edges and corners design, applied to a high-density birch board with high level polyurea wear resistant paint. It has very good waterproof, moistureproof, sun - proof and collision - resistant functions, available for outdoor tour. With special-shaped reinforcement, the design of large porous holes can protect the unit and meanwhile the resistance to air flow is very small, with strong penetrating force, can reduce the noise of turbulent air for the greater part, and in the case of large sound pressure, the vibration of the iron mesh will not produce abnormal sound.
  • It can be placed horizontally or vertically on the ground, convenient to use in different occasions. Such as all kinds of activity centers, theatres, clubs, DISCO PUB, music clubs, performance halls, music bars, high-end KTV, nightclubs, etc.
  • Combined with REYN AUDIO RL1 / RL0.5 / RX212 or RX210, can create better sound field effect and display the music style and the integrity of system .
