Quoted from PinballConspiracy:Is the JBL Stage 810 an easy Drop-In like the Goldwood? Is the difference in sound/Bass noticeable? Worth the price increase? Thanks! Great Thread!!
I put a JBL Stage 810 in my Godzilla. The hole pattern is exact fit but the bolts are a 1/2" too short. I removed old bolts with hammer and installed longer #6-32 bolts. I secured bolts with nut to cabinet then placed speaker on bolts and secured with second set of nuts. Works great. Did not bother with external amp. Set speaker balance to 6dB (to sub-woofer) and equalizers for 250 Hz. You can feel the base nicely. 4"Kickers were exact fit but wish I went the 5.25" route and mid-bass is not great.
