Check the listing for details. sE Electronics Reflexion Filter Pro Portable Vocal Booth - Red 25th Anniversary. Color: Red/Black Chrome (anniversary edition), Condition: New. Listed at 209.00 USD. The Easy, Portable Way to Make Recordings Sound Better! What an elegant and simple way to improve the sound of your acoustic space! Not everyone has the budget or the space to work in a perfectly "tuned" and treated acoustic space. But that doesn't mean you can't sound great. sE Electronics' Reflexion Filter Pro handles the job of making your mic sound its absolute best by surrounding the mic with six individual sound-diffuse layers. Better yet, it mounts to any mic stand — you can take this portable acoustic treatment into other rooms or to other locations! The Reflexion Filter Pro from Sweetwater costs a fraction of what a full-room treatment would cost, and it does an outstanding job taming the reflections in the room.
