Quoted from BallyKISS1978:It’s pinball not a high end audio producing format. That’s the point. Surround sound system benefits from a receiver to play high quality content from a Blu-ray. I don’t understand why you think you need to upgrade stock speakers for a pinball machine that runs 2.1 sound system fir audio that is not high digital quality. That’s my point. Just add a powered sub and the stock speakers are fine and not awful.
I have two sound systems and I know what really good quality sound sounds like, and for a pinball game stern speakers do a nice job. Added a Polk sub to my Elvira and adding a nice sub to any sound system makes a difference. You won’t hear much difference by changing the 4” stock speakers. It’s just a waste of time and money considering the source of the sound. If you don’t understand what I said oh well.
What you don't understand is that these machines have decent quality source material. Why would you not want to listen to this sound via better amplification and speakers? And that is the point. The source. Line-level outputs is as close as you can get to the source.
Since you have 2 home theater systems and that makes you an expert....(I don't like going down this road...) I personally own 21 a/v setups. Pinball is my 2nd hobby where A/V is my main hobby (I need to find cheaper hobbies). The majority of them use 4K HDR monitors and range from 7.2.2 to 5.1 audio systems.
I have personally designed 4 dedicated Home Theaters (1 for me and 3 for friends). 1 of them was featured in a Home Theater Magazine (the one in my home...of which I have pics in my profile). These ranged from mid end to high end. (separates with balanced XLR outputs etc...)
What you are saying is in effect this:
"The stock 4" speakers are fine for my purposes" If you'd actually say that, great.
But you are spreading your opinion as if it were fact. You haven't even heard a Spike2 with what I am talking about doing. How can you say it is a waste when you haven't even heard a pin like this? Also, note that I am talking about Line-level outputs. Doing anything to the sound at the boards speaker connectors is speaker-level outputs. At this point the sound has already gone through the boards cheap amp. This isn't an awful thing, but you always want to use line-level if you can. For example, Star Wars doesn't have line-level outputs for the subwoofer (only for the backbox), so for that I had to use the speaker level outputs to get a line-level output for the sub. But after Star Wars (or maybe the pin after it) they went to line level outputs for all of the sound channels.
I can absolutely assure you, if you grab the sound from these pins at the line level (which is before the sound goes through the cheap amp on the board) amplify it with a decent amp and push that sound to decent speakers, it is FAR better for most people. Stern added line-level outputs exactly for this reason. There is NO reason for the line-level outputs to exist for crap source material. Stern added them for a reason. Well, I am here to tell you about their reason.
I can't even believe that this is a discussion.
