Replace those factory speakers with the new Flipper Fidelity sound system. This system consists of (2) 4" coax speakers for the backbox, and an 8" woofer for base cabinet.
This kit is compatible with the following Stern machines:
Batman 66 Premium/LE/Super LE
Star Wars Pro/Premium/LE
Guardians Of The Galaxy Pro/Premium/LE
Iron Maiden Pro/Premium/LE
The Beatles Gold/Platinum/Diamond
As with all Flipper Fidelity systems, all installation hardware is included and nothing on your machine is harmed.
DUE TO THE DEPTH OF THIS BACK BOX AND THE LOCATION OF THE POWER SUPPLY, THE BACKBOX SPEAKERS MAY NOT FIT CORRECTLY AS STOCK. THE CARDBOARD SPACER RING MAY NEED TO BE REMOVED DURING INSTALLATION.
