Hello Pinside,
This is my first guide here so please be gentle!
I've been wanting to put upgraded speakers and Speak Light Kit on my #star_trek_le for some time now and I finally pulled the trigger.
I ran into some gotcha's along the way and have some tips to share for those that want to take this same journey. Hopefully learning lessons from this install will eliminate same frustration I had for others.
*edit - The frustration was entirely my fault as I misplaced a bag of 5/8 female/female standoffs.
First, inspiration came from the LOTR post

It was pretty clear the placement of the speaker grill make a huge difference in the quality of the acrylic insert so this was the plan from the start.
Speaker Panel -> acrylic insert -> Light Frame -> grill -> Speaker -> factory nut
The right speaker gets the ground cable between Speaker and factory nut.
The speaker kit came with 8 6-32 5/8" aluminum standoff screws which is great if you aren't going to use a Speaker Light Kit however not so great if you want to have the grill in the back.
The Speaker Panel has 4 6-32 rough thread studs per speaker. This means the supplies provided was insufficient to create this desired layering. I sent an update to Flipper Fidelity seeking input to get more of these 6-32 5/8" standoffs but didn't hear back nor are they for on their website so it was off to find these things in the wild.
Now for the frustrating part. It was quite difficult to find these standoff's but eventually found them on Amazon. Apparently they are out at the moment.

I would *gladly* pay the few extra bucks it would take to toss in 8 more of these standoffs to avoid scraping Amazon for parts that doesn't take 1-2 months to ship! Perhaps Flipper Fidelity and Speaker Light Kits can get in sync and document this "grill in the back" setup and offer these standoffs for sale
*edit - this install is possible without further purchases if you use the supplied female/female standoff. These were lost at the time of install.
If you wanted to go the way indicated in Speaker Light Kit instructions:
Speaker Panel -> acrylic insert -> grill -> Light Frame -> Speaker -> (alternately) factory nut
You can accomplish this same thing using 1-1/4" standoff for a clean install. It doesn't look as good externally, but I have posted it here in case anyone is curious.

Ok, now pictures of the right side, with stacked 5/8" standoffs. These are pretty self explanatory.
Here's the right Speaker with the Acrylic insert, Light Ring then the first 5/8" standoff

Next comes the grill, the next 5/8" standoff, then the speaker, ground cable and stock nut.

For the sake of documentation and comparison, here's the left speaker in the order of
Acrylic, grill, light frame, 1-1/4" standoff.

Finally the Speaker and the stock nuts.

Fire it up and you can clearly see the difference between the left and right speaker!

After fixing the left speaker to use the double 5/8" standoff and things look much better.

In case you wanted a closeup of the standoffs, here they are. Two 5/8" are stacked to show the same length as the 1-1/4"
standoffs (resized).jpeg
I hope this helps anyone in the future wanting to install the combination of Speaker Light Kit + Acrylic insert + Flipper Fidelity on a late model Stern SAM machine. Save yourself some headache and shoot for 16 total 6-32 5/8" aluminum standoffs. It will look much better and it allows you to use the stock nuts for a nice clean install.
*edit- again, headache is self caused by losing the supplied female/female standoffs.
If you don't lose the parts like I did then you don't have to fuss with this alternate method
Cheers
Dan
