RM 1283 SB Mk1

Dual 18" Bass Reflex Subwoofer

 

Features

- Dual 18-inch drivers with double dampers and triple-round surrounds deliver clear sound with powerful bass. The high-quality ferrite magnet provides optimal motor force, designed using FEA software technology. Additional cooling on the T-yoke and an aluminum ring help to effectively reduce distortion.

- High-grade birch plywood construction to minimize distortion.

- All sides are finished with a textured black surface and coated with a weatherproof layer to protect against water and outdoor conditions.

- Easy installation with mounting brackets on both left and right sides, suitable for use as both a flying subwoofer and a ground-stacked system.

 

Applications

The RM 1283 SB is designed to deliver wide output coverage with deep, impactful bass. This system is ideal as a main speaker due to its high performance. It is perfectly suited for outdoor and indoor music concerts, DJ performances that require strong low-frequency output, and permanent installations in large venues.

 

Convenience

With a total weight of 112 kg, the system is engineered to provide stability and ease of installation when placed on the floor. Integrated handles on both the left and right sides assist in relocating the unit when needed.

 

Compatible with Line Array from Rhyme Pro Audio

When combined with line array, the low frequencies are fully handled by the RM 1283 SB, resulting in more powerful bass, while the line array can focus on delivering clean and clear high frequencies.
