Introducing the UK-RBM Series

A New Era of British-Built Bass Amplification

Ashdown Engineering is proud to introduce the UK-RBM Series - a brand new range of UK-built bass heads and cabinets designed to magnify the essence of bass tone with power, precision, and unmistakable Ashdown character.

Handcrafted in the UK and engineered for modern bassists, the UK-RBM Series represents a bold step forward in tone, reliability, and performance. Built for players who demand professional capability in a compact, gig-ready format, this new line blends upgraded UK construction with the tonal DNA that has defined Ashdown for decades.

Powerful, Lightweight UK-Built Bass Heads

The UK-RBM Series launches with two lightweight bass heads: the UK-RBM-800 and UK-RBM-500, both finished in a striking Ice Blue and designed to deliver maximum performance without necessary weight.

Despite their compact size, the UK-RBM heads offer serious output - 800 watts and 500 watts respectively - making them equally at home in rehearsal rooms, live venues, studios, and home setups.

Both heads feature Ashdown's iconic tone-shaping tools, including the Sub-Harmonic Generator for rich, octave-enhanced low end, smooth onboard compression for controlled dynamics, and valve-emulated overdrive for anything from subtle warmth to aggressive bite. A flexible FX Loop allows seamless integration with pedals, while headphone output, traditional DI, and analogue Ashdown Cab Sim DI provide comprehensive connectivity for modern playing environments.

Hand-assembled in the UK using upgraded components, the UK-RBM heads deliver powerful, articulate tone with the reliability working bassists expect from Ashdown.

Premium UK-RBM Cabinets: Built to Match

To complement the new heads, Ashdown introduces three UK-crafted cabinets, each designed to deliver a distinct tonal personality while sharing a refined, cohesive aesthetic.

Finished in Charcoal Tweed with Silver Weave grille cloth and the classic Ashdown double-wing badge, the UK-RBM cabinets combine modern design with a timeless Ashdown look.

UK-RBM-112T - Compact Punch and Clarity

A 300-watt 1x12" cabinet featuring a high-efficiency Sica NEO 12" driver and adjustable tweeter. Designed for articulate, full-range performance in a compact footprint, it's ideal for gigging bassists seeking premium portability without compromise.

UK-RBM-115T - Deep, Room-Filling Low End

Equipped with a powerful Sica NEO 15" driver, the UK-RBM-115T delivers warm, rounded lows with impressive definition. Perfect for players who want authoritative low-end presence while keeping their rig manageable and lightweight.

UK-RBM-210T - Fast, Punchy Projection

Loaded with dual Sica NEO 10" speakers, the UK-RBM-210T offers tight, responsive lows and articulate mids. A versatile option for modern bassists who value clarity, speed, and controlled projection on stage.

A New Benchmark for UK Bass Amplification

With the launch of the UK-RBM Series, Ashdown continues its tradition of building dependable, musician-focused equipment - now with renewed emphasis on UK craftsmanship, modern efficiency, and signature Ashdown tone.

Whether one stage, in the studio, or at home, the UK-RBM range delivers the powerful, expressive sound bassists expect from Ashdown, refined and reimagined for the next generation.
