The Rock-Box CRM90 impulse response library captures and is seeking to recreate the sound of Celestion® Cream speakers loaded in Rock-Box cabinets. Impulse response files are provided in Wave Audio Format (.wav), and have been minimum phase transformed using a proprietary algorithm. The Rock-Box cabinets are proprietary enclosures, designed and built in-house singularly for impulse response capture and towards multiple sound design goals: •to maximize fidelity and musicality for use in a broad range of styles and applications •to provide a tone that is both something familiar and something new •to exude a neutrality that allows the individuality of different speakers, guitars, pickups, amps, and playing nuances to shine through unencumbered.
