Celestion Ruby Impulse Response – Oozing With Rich Musical Warmth


The latest Celestion speaker to be captured digitally by our expert sound engineers and join our ranks as an impulse response is the gorgeous Celestion Ruby.

The Ruby is a speaker designed with an alnico magnet and purpose-built to create vintage tones, whether loaded into a 1×12, 2×12 or 4×12 cabinet. The Ruby is the newest addition to Celestion’s alnico speaker family that also boasts the legendary chime of the Blue, the dark punch of the Gold and the effortless refinement of the Cream. It brings the instantly familiar Celestion alnico vibe with its glorious, dampened attack – oozing a richly musical warmth, with mellow highs and a smooth, sophisticated midrange.

A New Spin On Alnico Voicing

The versatile Ruby is voiced to combine the heralded chime of the ever-popular Celestion Blue with the vintage-rock attitude of the Gold and the contoured warmth of the Cream. This new spin on the timeless Celestion alnico voicing that the Ruby achieves seems to imbue amp settings that may have previously seemed lacklustre or strident with a lustrous new life, coaxing previously undiscovered sweetness, balance and depth from your tone that always seems to sound just right!

Celestion Ruby Speaker Impulse Response

Now, Celestion’s sound engineers have expertly captured the Celestion Ruby in digital form as a speaker impulse responses and is available to download in five different cabinet configurations, to provide the user with the full spectrum of warm, vintage tone the Ruby has to offer:

  • 1×12 (closed back)
  • 2×12 (open back)
  • 2×12 (closed back)
  • 4×12 (closed back)

These cabs were recorded in a world-class room using three of our favourite microphones, the Shure SM57, Sennheiser MD421 and the Royer ribbon mic. Each of these three mics, in turn, were recorded in six fully-adjustable positions around each 1×12, 2×12 and 4×12 cab (plus a rear mic for the open back cabs). These positions are named within the IR files as Balanced, Bright, Fat, Thin. Dark and Dark 2.

An additional Neumann TLM107 room mic was also used to provide a truly huge range of mic mixes and tonal options for the user to experiment and play with.

These Ruby cabinet configurations can either be downloaded or as a full collection with a discount of up to 50%. As with all our other best-selling ranges of IRs, the Celestion Ruby IR is downloaded in .WAV format to ensure full compatibility with the majority of amp modelling software.

This speaker impulse response is a perfect digital representation of the Celestion Ruby and is the sophisticated alternative to other alnico-backed speakers, such as the Celestion Gold, Blue or Cream. Add that instantly familiar, warm alnico tone to your playing today!
