Celestion has unveiled the Celestion 100 Impulse Response Collection, a downloadable library of impulse responses that capture the tone of the Celestion 100 loudspeaker — recently introduced in 2024 commemoration of the company’s 100th anniversary — for any digital music production platform, including digital audio workstations for recording and modeling amplifiers for performance.
The Celestion 100 traces its roots to the original G12, a general-purpose 12-inch radio speaker that was later fortified to meet the evolving demands of electric guitar amplification in the 1950s and ’60s. This iteration became the T530 or “Alnico Blue,” which worked was installed in the Vox combo amps (a favorite of The Beatles) that powered the “British Invasion” of the early 1960s. Today’s hardware Celestion 100 is designed to deliver the tone of those early alnico speakers and their many descendants and variants, but with more durable materials.
The new responses digitize these sonic characteristics via a meticulous recording process, beginning with studio-quality, go-to guitar cabinet microphones such as the Royer R-121 ribbon, Shure SM57, and Sennheiser MD421. Each IR thus offers a variety of mic type and placement options and can be loaded into any IR host within a DAW or into stand-alone amp modeling hardware.
The complete Celestion 100 IR Collection includes five cabinet configurations:
— 1 x 12 open-back
— 1 x 12 closed-back
— 2 x 12 open-back,
— 2 x 12 closed-back
— 4 x 12 closed-back
These reflect the most widely used setups for studio recording and onstage use across single, dual, and four-speaker cabinet sizes. Each of these can also be purchased and downloaded as a single impulse response, though the full collection represents a significant cost savings compared to buying IRs individually.
The Celestion 100 Impulse Responses join a family of IRs that includes the Shades of Greenback Collection, G12-50GL Lynchback, Neo Creamback, Copperback, Hempback, Vintage 30, and many others. They’re available for download as individual IRs and as a complete collection at celestionplus.com.
