Ashdown Rootmaster UK-RBM-112T 1x12" 300W Bass Speaker Cabinet - Charcoal Tweed

Handbuilt in the UK for bassists who want powerful tone without a heavyweight rig, the Guitar Center Exclusive Ashdown Rootsmaster Bass Magnifier UK-RBM-112T 1x12" bass speaker cabinet combines a Sica NEO 12" driver with an adjustable tweeter in a compact 300W design. The neodymium driver provides tight lows, clear mids and articulate response, while the tweeter lets you tailor the cabinet's high-frequency character. Ply construction keeps the cabinet weight to 33 lb. for easier transport between rehearsals, sessions and performances. Genuine Neutrik speakON/1/4" combo connectivity and a Charcoal Tweed finish with Silver Weave grille cloth complete this UK-built bass cabinet.

Sica NEO 12" Driver for Clarity and Punch

At the heart of the UK-RBM-112T is a Sica NEO 12" speaker designed to provide tight lows, defined mids and articulate response. Its lightweight neodymium magnet helps reduce overall cabinet weight while keeping bass lines clear and present. Rated for 300W at 8 ohms, the UK-RBM-112T provides a responsive foundation for a range of bass tones and playing approaches while maintaining the portability that distinguishes this compact cabinet.

Adjustable Tweeter Provides High-Frequency Flexibility

An integrated high-frequency tweeter complements the Sica NEO 12" driver with additional definition and presence, while a three-position switch provides direct control over its contribution to the cabinet's sound. Choose the Hi setting for greater high-frequency detail, Low for a more restrained response or Off to hear the 12" driver without the tweeter. This simple adjustment lets bassists tailor the cabinet's high-frequency response to suit different instruments, sounds and performance settings.

UK-Built Construction for a Portable Bass Rig

Built in the UK from ply, the UK-RBM-112T combines a manageable 33 lb. weight with a compact format for easier transport between sessions and performances. Genuine Neutrik speakON/1/4" combo jacks provide versatile connectivity, while the Charcoal Tweed finish, Silver Weave grille cloth and Ashdown's classic double-wing badge give the cabinet a distinctive appearance. Available as a Guitar Center Exclusive, the 300W UK-RBM-112T works as a standalone bass cabinet or as part of a modular UK-RBM rig.
