GrillEffects (acrylic speaker inserts) for your Stern Avengers These add that next level of immersion for those with speaker lights or a colored fabric background. They provide a stealth like appearance when the lights are off and do not impact sound. These work great combined with speakerlightkits.com Stern Spike 2 kits (type 11/12/14), or with any new MythPinball.com LED Light Frames. (I recommend using the foam + canvas diffuser) Available in lots of different combinations. Message me for any combo not listed. Any questions please ask before ordering. NOTE: The Avengers A logo is left and right specific.. all others can be installed on either left or right side. Set of 10 includes the following: -Avenger A left -Avenger A right -Black Panther -Black Widow -Doctor Strange -Hawkeye -Hulk -Iron Man -Iron Man pulsor -Thor >> Install instructions <<
