Stern Pinball Speaker Adapter 4" to 5.25"

thingiverse

4 inch to 5.25 inch speaker adapters designed for Stern LCD Pinball machines to upgrade the Pro or Premium speakers to the LE size. This should work in any Stern game that came with the 4 inch speakers to install 5.25 inch speakers but was designed for SPIKE 2 (LCD) and SPIKE 1 games. For great results it is recommended to install the same speakers that Stern has used in many LE's: Kenwood KFC-1366S 250 Watt 5.25-Inch Coaxial 2 Way. These can be found for less than $40 at many retailers including Amazon. These speakers are slim enough to fit the right side of the backbox without hitting the power supply enclosure and on the front side the tweeter doesn't extend forward to hit the grill. Other speakers might fit this location and sound good, but the Kenwoods are known to fit and used by Stern themselves.
