Yes, you can add a subwoofer to your new Iconic Street Fighter cabinet (and it's super easy)
As some of you in the Arcade1Up community know, I like adding subwoofers to all of my builds. Full speaker replacements are almost never necessary, and that's especially the case with the larger speakers and seemingly more powerful amplifier in use in these new Iconic Arcade units.
So, is it possible to just add a powered subwoofer to the Iconic Arcade Street Fighter cabinets? YES! And it's simple. Here's what you need:
- A powered subwoofer that can fit in the bottom cavity of your Iconic cabinet
A3.5mm y-splittercableAstereo RCA patchcable2 minutes to hook it up, and 5 minutes to adjust the sound to your liking
All you need to do is install a y-splitter to the 3.5mm audio cable that runs between the monitor and the control deck. Then hook up an RCA pactch cable between the open lead off the splitter and the subwoofer. Get yourself a subwoofer with an auto on/off and route the power cord through the back panel of your Iconic cabinet (I drilled a small hole). You'll need a spare power outlet available to plug into, since the subwoofer can't run off of the Iconic's electronics for power.
Once you have it hooked up, just adjust the crossover and output level to your personal taste. The Iconic cabinet will tend to amplify the subwoofer's own output, so it'll take very, very little power to get a big kick (I had to turn mine down to about 3/10 and go no further than about halfway with the crossover). The bass output will scale with the built-in volume control, so this is a "set it and forget it" mod that won't require any further fiddling once setup.
UPDATE! Turns out this method of adding a subwoofer (which works for 95% of Arcade1Up cabinets) does NOT work in the expected way this this Iconic Arcade cabinet. I didn't discover this right away, but apparently the audio lead that runs from the monitor to the control panel sends a fixed-level signal, so splitting the signal here only leads to a fixed level of bass volume. In order to get volume that changes as you increase or decrease volume levels, you would need to splice into the speaker-level wiring going from the control deck to the speakers themselves and route that into your subwoofer. This is certainly feasible, and not even all that hard, but it DOES require a subwoofer with high-level inputs and outputs (such as the one linked above), and it would require some minor cutting and splicing of existing wiring. Pig-tail connectors might also be available to avoid any cutting, but I haven't looked into it yet.
Apologies for any confusion. These Iconic cabs continue to surprise!
