friggin gorgeous, every little detail!
I'd bet its fantastic to play and a video might show the differences to people who know how a typical BOP machine behaves, no doubting what you've done being tons livelier.
dang she's a meannie, watched PAPA video of gameplay as comparison, it seemed much more tame.
he was doing better with sends to right flipper for face ramp shots, your redo work looks like it doesnt give time to get control like that as often.. it's fast!
the speakers I like are the inexpensive (not junk) very efficient paper cone cloth surround woofers from MCMelectronics.com, typically 94+ db from the 1st watt of power input for 8-ohm voicecoils is a lot of bark, even if the original was 4-ohm thats tough to beat.
you can get bigger thump from same amp, and it's running cooler doing it.
my experience is running them with small power 12v Lepai audio amps, about on par with whats inside most pinball machines. with small power, speaker efficiency is everything!
backbox speakers are likely decent enough, so it's about 15-20 bucks for a better 8-10" woofer that might get some people wondering how theres so much bass without external sub..
(especially if you can slip one of their 10's or 12's in there)
havent installed into pinball machines but LOTS of experience using them with very small Lepai amplifiers. I've got many pairs (spares too) of the MCM paper/cloth woofers, I like building speaker cabs. lots dont know, 7-8 actual watts can be -very- loud with efficient drivers.
pinsider markmon wrote an "add a subwoofer" thread, he specifies MCM woofers too. a couple people kinda argued "it isnt a sub unless its active/separate/powered", maybe they just dont understand. when you replace a speaker that gives 87-89 db from 1 watt with one that can pump 94+, its easy twice as loud more bass etc, no real need for another amp.
"blue resistors"? would those be capacitors and coils (low pass) to cut out higher frequencies?
if so, yup, leave them in and swap the woofer to see what it has to say for itself. small difference of 4-ohm vs 8-ohm might change cutoff frequency a little/barely, if they are different. if they're actually resistors, like 8 ohm amp needing 2-3 ohms in series to a 4 ohm speaker, probably wouldnt need that connecting an 8-ohm voicecoil.
the MCM are really inexpensive but their sensitivity makes them great for lower wattage, worth a try especially if you dont want more stuff on the floor like an external powered sub.
