Combining a versatile 1x15" speaker configuration with a lightweight design, the Ashdown Rootmaster RM-115T-EVO III bass speaker cabinet provides 300W of power handling in a portable format weighing just 33.3 lb. A custom-designed 15" Ashdown speaker forms the core of the cabinet, while a selectable three-position tweeter provides additional control over high-frequency response. Lightweight plywood construction, a top-mounted bar handle and genuine Neutrik speakON/jack combo connectors make the RM-115T-EVO III easy to incorporate into rehearsal and performance rigs. Finished in Buffalo Tolex with metal corner protectors and silver grille cloth, the cabinet combines Rootmaster styling with a practical 1x15" platform for a range of bass setups.

Custom 15" Ashdown Speaker With 300W Power Handling

The Rootmaster RM-115T-EVO III is built around a custom-designed 15" Ashdown speaker with 300W of power handling. Housed in a closed-back cabinet, the single-speaker configuration provides a straightforward foundation for a range of bass instruments and playing styles. The 1x15" format also makes the RM-115T-EVO III a practical option for players building a modular head-and-cabinet rig around a single-driver speaker configuration.

Three-Position Tweeter for Adjustable High-Frequency Response

A selectable three-position tweeter gives the Rootmaster RM-115T-EVO III additional control over its high-frequency response. The High setting provides the strongest tweeter level, Low reduces the tweeter contribution, and Off removes the high-frequency driver from the speaker system. This allows players to adjust the cabinet's upper-frequency response to complement different instruments, playing styles and tonal preferences.

Lightweight 1x15" Cabinet for Easy Transport

Built from lightweight plywood, the Ashdown Rootmaster RM-115T-EVO III weighs just 33.3 lb. for easier transport between rehearsals, sessions and performances. A top-mounted bar handle provides a convenient carrying point, while genuine Neutrik speakON/jack combo connectors support connection to compatible bass amplifiers. Buffalo Tolex, metal corner protectors and silver grille cloth complete the Rootmaster cabinet design.
