Celestion G15V-100 Fullback 8 Ohms

A 15-Inch Speaker That Challenges Celestion's Norms

A historic reference in guitar amplification, Celestion has shaped the rock sound with its 12-inch speakers. The G15V-100 Fullback offers a different approach: maintaining Celestion's musicality while benefiting from the larger radiating surface of a 15-inch speaker. The result is a deeper low end without sacrificing midrange richness, providing an expanded palette within the same sonic family.

Intended Use and Target Musician

This speaker is designed for guitarists seeking more low-end foundation without losing midrange attack and clarity. Suitable as a replacement or customization for a 15-inch combo/cabinet, it fits rock, blues, roots, light stoner, or traditional jazz styles, both in studio and on stage, with standard or slightly down-tuned setups.

What the Fullback Brings to Your Tone

Extended Response and Tonal Balance

With a specified frequency response from 65 Hz to 4 kHz, the Fullback broadens the harmonic base and adds foundation to the sound while preserving nuanced mids that cut through the mix. The highs remain smooth and free of harshness, delivering singing crunch tones and warm cleans.

Efficiency and Dynamics

The 99 dB sensitivity ensures comfortable volume at equal amplifier power, with good headroom before compression. Attacks are firm, and the low-end remains tight, helping palm-muted riffs and open chords stay clear.

Durable Design

The steel chassis stiffens the assembly to limit unwanted vibrations, while the ceramic magnet guarantees a stable and predictable response. The 2-inch voice coil handles temperature rises from sustained sets, ensuring reliability.
