Has anyone done this before? I’m thinking about a modern Stern (I own GoT). How difficult would it be to remove the base cabinet speaker and install a powered sub in its place? You could use the existing speaker wire, install an amp and new speaker and your good to go; right? It could be plugged into the service outlet or tapped in, to get power from the game.

Would it be better to leave the original cabinet speaker and add a 2nd speaker (powered sub) into the back of the pin. Either cut a new hole for the 2nd speaker or use an in-wall induction speaker that mounts onto the cabinet. If it’s just for bass sound quality shouldn’t be to much of an issue.

What about upgrading the stock speakers to a flipper fidelity package. Would that be enough that you wouldn’t want to add an external sub.

I understand that this is the easiest way to add some bass, but I’m not keen on having a sub on the floor under the pin. I’d prefer an option enclosed in the game.

I have a shaker on my game and I guarantee you that no speaker would move a cabinet as much as a shaker motor does. Unless of course it’s a 15” sub playing a loud 20hrz signal. Music playing bass wouldn’t have as noticeable of an effect as a shaker motor.

So the flipper fidelity package is a huge upgrade over the stock speakers, but is it as noticeable as a sub on the floor? My stock speakers are loud enough for the room, but I’d prefer a more full sound with rich deep bass.

Oh, I agree that the glass may rattle, but noting like a shaker motor will do. IMHO

I built a virtual pin from scratch and used a 2.1 plate amp with 2 coax speakers and a sub in the bottom of the cabinet. That worked out well. I didn’t notice and glass rattle; although I do currently hear the glass in Game of Thrones when the shaker goes off. (Maybe my build quality is better then Sterns)

This is very true. For great sound you need to have an enclosure tuned for your speaker. I have great sound from my home theater, this is just pinball. It could be better but I’m not hoping for anything to spectacular.

Ok. I agree that a stand alone sub would sound the best. ( but for sake of argument let’s say that a sub on the floor won’t work for this location)

I always thought that FF systems came with an additional amp to power them. If not then they’re outta the question. What’s their special sauce? Just A crossover?

I think that it would work fairly well and could sound much better then original. Just by adding a powered amp like Spooky Pinball does and swapping out the cabinet speaker with a matched sub. Something with a variable crossover so that you could tune it to sound best for the game it’s in.
