Suhr Reactive Load I.R. Box

Cab Simulator and Attenuator


Here's what Suhr say about the Reactive Load I.R:

The new Reactive Load I.R. builds upon the legacy of what is already widely regarded as the industry standard for accurate speaker cabinet load replacement: the original Suhr Reactive Load. Reactive Load I.R. incorporates exciting new features to the groundbreaking design of the original Reactive Load – making it the ultimate all-in-one solution for speaker cabinet replacement

As the name suggests, Reactive Load I.R. adds impulse response technology to the original Reactive Load, allowing you to quickly and easily access an array of an expertly mic’d speaker cabinets. It comes preloaded with 16 Suhr speaker cabinet impulse responses captured by Celestion. Reactive Load I.R. is an open system, so you can load 3rd party impulse responses via the USB port.

In the Studio

The Reactive Load I.R. is virtually indistinguishable from a mic’d speaker cabinet which allows you to get professional quality sound in any room. Engineers will love the ability to use both outputs to simultaneously record the dry signal and the I.R. effected signal for maximum flexibility when mixing.


Reactive Load I.R. is also the ideal practice tool. The auxiliary input allows you to plug in your smartphone or other audio source and JAM along to your favorite songs through the headphone output, all while using your tube amp. Practice silently, no DAW required.

Playing Live

The Reactive Load I.R. eliminates the need to mic your speaker cabinet and gives you the ability to send the FOH engineer a perfectly mic’d guitar sound that is consistent night after night, without mic bleed issues.

Pre-loaded with authentic Suhr cabinets

Included with Reactive Load I.R. are 16 impulse responses of authorized Suhr speaker cabinets created by Celestion. Included are impulse responses from the Suhr Badger, Bella, Hedgehog, PT, and 412 cabinets. For a full list of included impulse responses, please see the user guide. Reactive Load I.R. is an open system, which means you can connect it via USB to a computer and load your favorite third party impulse responses.

Industry standard reactive load.

The original Reactive Load is renowned by many as the standard for speaker cabinet load replacement. The same dynamic, analog accurate, load technology is at the heart of the Reactive Load I.R.

The load circuitry has been meticulously designed to preserve the character, nuance of tone and the essential feeling of being connected to a real cabinet. The addition of impulse response technology allows for speaker cabinets and microphones to be sampled, not just simulated, making I.R.s sound virtually indistinguishable from a real cabinet and mic.
