The IRF2 has been discontinued,
but we suggest you check out the guitaRF® instead.

The IRF2: compact, but just as powerful as the original.

With an Instrument Reflexion Filter®, you can get acoustic treatment into the smallest of spaces that a normal filter dare not go.

With the same patented technologies as its larger siblings, the IRF2 was designed for drums, guitar cabinets, pianos, and confined spaces in general.

The IRF2 uses a small curved wall of punched aluminum with 3 layers of polyester fiberboard separated with air gaps. These layers combine to help reduce room or stage ambience and isolate the mic from unwanted external noise.

Not just for the studio, the IRF2 is used live on stage by artists ranging from Tom Petty to Paramore (on guitars) to Steve Winwood (on a saxophone) to My Morning Jacket (on a Fender Rhodes through a guitar amp).


The IRF Studio Kit

The IRF Studio Kit is comprised of five pieces of IRF2 in a sturdy flight case, and is ideal for touring drummers, orchestral applications and professional studios with multiple instrument miking applications.


"The IRF2's reduce spillover for the recording as well as for the front of house and monitors, I put them on guitar amps. The keyboardist plays a lot of Fender Rhodes [piano] through a Fender Twin, so I put one on his amp, as there's also a wedge blowing back into it. There's also one on the bass amp, because it's usually pretty close to the drummer's ride cymbal."
