Sica NEO 12" Speaker With High-Frequency Tweeter

At the heart of the UK-OBM-C112-500 is a Sica NEO 12" speaker designed to provide tight lows, clear midrange and articulate response. A high-frequency tweeter complements the neodymium driver with additional upper-frequency definition, while the lightweight neodymium magnet helps keep the overall combo weight to 30.9 lb. The kickback cabinet design lets you angle the speaker upward for personal monitoring during rehearsals and performances. When additional output is needed, connecting a compatible 8-ohm extension cabinet lets the amplifier deliver its full 500W output while expanding the speaker system for higher-volume playing environments.

5-Band EQ and Shape Control for Flexible Tone Shaping

A 5-band EQ provides detailed control over the UK-OBM-C112-500’s tonal character, with bass, low-mid, mid, high-mid and treble controls covering key areas of the frequency range. Each band provides ±15dB of adjustment for shaping low-end weight, midrange presence and high-frequency definition. A selectable passive/active input accommodates basses with different output levels, while Ashdown’s signature VU meter provides visual feedback for monitoring input level. The Shape control provides quick access to a familiar Ashdown tonal contour for fast adjustments.

Flexible Connectivity in a Portable UK-Built Combo

An FX loop integrates pedals and external processors into the signal path, while the balanced DI provides a direct connection to front-of-house systems or recording equipment. A headphone output supports silent practice, adding another option for everyday use. Built in the UK and available as a Guitar Center Exclusive, the Ashdown Original Bass Magnifier UK-OBM-C112-500 combines expandable output, flexible tone shaping and practical connectivity in a compact 30.9 lb. bass combo.
