The Celestion Ruby 4×12 (closed back) speaker impulse response was purpose-built to create gorgeous vintage tones. Bringing an instantly familiar alnico vibe, the Ruby oozes a rich musical warmth with a smooth, sophisticated midrange and mellow highs. In its 4×12 (closed back) configuration, this speaker impulse response delivers a sweetness, balance and depth that always seems to sound just right!

This 4×12 closed back speaker impulse response was recorded by our expert sound engineers in a world-class room using three high-quality microphones: a Royer ribbon mic, a Shure SM57 and a Sennheiser MD421. Each of these mics were recorded in six positions and named within the IR files as Balanced, Bright, Fat, Thin, Dark and Dark 2. An additional Neumann TLM107 room mic was used to offer extra mic mixes and to provide users with as many tonal options as possible.
