New Astro city. New power supply and jamma harness

While that's true, I didn't think this was a secret
maybe not a secret but something a lot of people don't seem to realize. I often see people buying $4 drivers and proclaiming that they must be high quality because they're the same ones that Bose use... :/
Oh God... are they in for a surprise.. :S
 
Bose has never been about drivers, Bose focus 100% on the electronics. Actually they have always said that they don’t release and will never release any kind of technical information about the drivers they use.

so yes, if you take a driver out of a Bose speaker. It’s no longer Bose.. it might sound like crap or it might not, but if it sounds like crap, you can’t blame Bose about it.
 
I just use cheap Visaton ones. They're the correct size. You'll have to cut the positive terminal though with a pair of snips, as the terminal is too wide for the connector.

I think they sound fine? If you're running jamma games, most of them have terrible sound, so it's not like super expensive speakers will make much of a difference (or even any).

Good quality speakers (and amp) only highlight the terrible stuff in sound even more ;)
But of course they highlight the good in proper sounding games as well…
 
I blew my amp because the cab's speakers were still wired to the main 18 pins AMP UP connector (through the 4 pin connector with the white loop) when I connected it to the NVS-4000 (green rect on my picture). Both the inline fuses on the stereo amp card were blown as well as the amp. Replacing these parts fixed the issue so at least it could be repaired.

The cabs speakers must be connected to the NVS4000 Audio Out (4 pins AMP connector), in the end what happened for me was more about forgetting to remove the speakers connector from the "main" AMP rather than being mislead by the informations on the PSU.
I’m having a few issues, and was pointed here.
I’m very confused.
R1 was fried on my amplifier, and since has been fixed, fuses are good.

Are you saying …
NEVER PLUG SPEAKERS IN the looped female that comes from the DC OUT Port?

Like this?
And always have them in speaker out port, for jamma and rca stereo to speaker in use?
If so, for jamma mono, is anything else needed? Such as… does anything need to be in speakers in?
 
Check the attached picture :

The looped female port is left empty.
The cab's speakers are plugged to "SOUND OUT".
I do have a cable with RCA connectors (for PCBs that have Stereo sound) that is connected to "SOUND IN".
For regular Jamma mono you don't need anything as the AMP will route the Jamma sound to the speakers.

In the case I play a PCB without Stereo sound with my setup I just leave the RCA cable laying inside the PCB compartment (making sure it does not touch any metal for good measures).

Bumping this thread with information about the Astro City 2 speakers.

The cab I bought came with some nice aftermarket 4ohm/15watt speakers, whereas the AC2 takes 4ohm/40watts. The upgrade to these are amazing. Definitely the loudest and boomiest sound out of any traditional candy.

The speaker boxes are marked with the model speaker inside the box, these three are "302", the other one (not pictured) was a totally different number.

I swapped the boxes around from this set from China with the ones originally in the cab as they were rust free.

I guess it is safe (and sad) to assume that this set of speakers is rotting away from age/being on site? Or it could be dust? I didn't want to pry any further in case I started doing damage to the cone. The sound doesn't seem to be affected at this point (as compared to my Blast City speakers which are toast).

Apparently, the status quo is that these speakers are Bose, however I couldn't find any markings to suggest so, and a google search shows up empty with the model number.

One of the best things about AC2 is that it's just the red and black wire to install, no need for having to pull out the soldering iron or crimp some wires.

Hope this brief insight is helpful to someone. My AC2 is a dedicated DoDonPachi machine, now my "Power Up" comes with a lot more punch and bass.

Sorry for bumping an old thread.
Ive owned an Astro 2 since 1999 as well. A few years ago I uploaded an English user manual to the popular arcade websites (got the manual from Sega UK).
Looking in there, I was surprised to see in fact that the parts list had options for either 130-5096 , or 130-5078

The 130-5096 speakers are the ones rumoured to be 'BOSE'
The 130-5078 are 'YST' Yamaha manufactured. Exterior cosmetic only difference is the casing is gloss black instead of flat black

I have my current 130-5096 connected to an amplifier and they have a nice deep bass sound to them.

Ive just made a purchase from Italy for a pair of 130-5078 as Im genuinely curious of what the difference in sound will be like, even though this is all very old technology to today standard :D

ill report back when they finally arrive.

Bumping this thread to see if anyone has recommendations for replacing the Astro City speakers on current day. Older posts recommends US speakers but I'd like to see if there's any Ali Express speaker that can be a drop in replacement.

I've been playing with an Logitech Boombox on top of the machine so using the stock speakers became disappointed. I want to find where to buy new AMP UP connectors to make a new stereo mod from an amplifier and also replace the speakers at the same time.

Ps.: found the speaker system @djsheep shared from the Astro 2 super super cool!

Thanks!

Back in the day i fit z5500 speakers into an Astro City 1, which were actually Tang Band W3-593SF
Not sure if theyre still available as easily anymore, but in case you find an old z5500 set on marketplace, would be worth picking up if cheap.
Post I done in 2015:
https://www.aussiearcade.com/topic/...ro-citys-consoles-updated/#findComment-860152
Otherwise id use the specs from that tang band speaker in terms of measurements if youre looking for another full range 3" speaker, for ease of mounting.

Hey mate. The ones linked in this post -
https://www.arcade-projects.com/thr...wer-supply-and-jamma-harness.6092/post-114300 - are amazing.

I have them in my Astro now, they have good definition and loudness. A bit lacking on the bass but a massive improvement to the originals.

Never found a replacement for New Astro City (4ohm) but have gotten used to the OG’s.
 
Figure out the existing outout specs, size and spacing between mounting holes. Search parts-express.com and make sure you select a model that is shielded.

I've bought all my speakers this way and they are usually peanuts as there isn't much of a use case for a lot of these now.

I use these same speakers in my Astro and also in my Wangan speaker boxes and they are excellent. Parts express stocks them https://www.parts-express.com/HiVi-B3S-3-Shielded-Aluminum-Driver-Square-Frame-297-427?quantity=1

Definitely more bass than stock but nothing beats adding a subwoofer inside your cabinet :)
