The Speakerbox series has been merged into the BIGBox collection. We've kept the information below for reference purposes. You can purchase these IRs on the BIGBox page. Thanks for your support and patronage.
* Take a look at the IR Matrix, for each speaker, for a complete listing of captured impulse responses.
- Sampled with 12+ industry-standard microphones each with their own special sound
- Up to 9 mic positions to dial in the right tone for your amp
- 9 different mic distances for different amounts of proximity effect and room ambience
- 500+ IRs per speaker* so you'll find the perfect match for your sound
- Edited for better phase coherence allowing you to more easily mix multiple IRs
- Clean, uncompromising signal chain that won't add undesirable color to your sound
- Speaker powered with Bryston 2B/4B, known for a flat freq. response and low distortion
- Recorded with Lavry Blue converters for top quality AD/DA conversion
- Sampled with a Neve 1073, a highly regarded preamp for recording guitar
- Compatible with a wide range of recording software and convolution plug-ins (see Compatibile Software) including Axe-Fx ready sysex files**
**Axe-Fx sysex files are truncated to 1024 samples to conform to its cabinet IR size limits, thus removing room reflections
We mic each sampled speaker from 9 positions. The primary positions include: Cap center, Cap 45° off axis, Cap edge, Cap edge 45° off axis, Cone middle, and Cone edge. The captured
sound is brightest (contains the most high frequency content) at the "Cap center" position and gets progressively darker (more lows and less highs) as you move the
mic towards the edge of the cone. Proximity effect will boost the lows (sometimes A LOT) the closer the mic is to the speaker.
Depending on the speaker and your application, you may find certain positions more useful than others. For instance, the Cap position might be just the ticket to add some definition to a muddy guitar part.
Or, you may find it useful to boost the highs when using the Cone IRs... consider using a high shelf to add some presence and some "air". The point is, there's a potential use for every IR in the collection.
In addition to the primary mic positions, for our Weber Blue, we used each microphone as a Mono Room mic at a distance of about 6 feet, midway between floor and ceiling and pointing it away from the
speaker to catch primarily reflected sound in the case of cardioid mics.
A "Stereo Room" impulse is captured with a matched pair of Neumann KM84s or Earthworks TC30s in an XY configuration. We split the stereo signal into to two mono, left-right signals for convenience. We also use a KM84 or TC30 to sample the back of the cabinet at distance of about 12".
We reverse the phase of this sample. It picks up mostly low end and room reflections and may be useful when blended with a another mic signal. For our Weber Blue we placed a BLUE Bottle with a B4 Omni capsule, placed about 5' and 10' (labeled Alt) off the
back wall, as a neutral Mono Room mic.
Not every mic was sampled in every position and at every distance so check the IR Matrix for a comprehensive listing. We like to try different things, so each sample set has a few surprises.

Click on the mic name to see a brief description. Not every mic was used on every cabinet so check the IR Matrix of each cabinet for details.
We sampled each speaker and microphone combination at up to 8 distances: 0", 0.5", 1", 2", 4", 6", 12", and Room. For the Weber Blue, we were going for a roomier sound so we used 9: 0", 1", 2", 4", 6", 12", 24", 36", and Room..
As the mic gets further from the speaker, the captured sound tends to get progressively brighter as the low-end drops off. You get more ambient room sound the further away you place the mic. The 0" starting position is right on the grill, but not touching it, or parallel to the baffle in the case of cabs without grills or grill-cloth.
