This is our ARF-12. It’s smaller but heftier than the ARF-32. It looks about the same on the outside but on the inside includes an additional layer of acoustic fiberglass, an air space and an additional perforated aluminum barrier. The hardware includes a swivel mount for more usable angles and for mounting on a boom.
This is a really handy filter for use in front of amps as well as recording acoustic guitars and drums.
