Occasionally I start researching speakers for the Astro City and Egret II, don’t find much, then give up for a few months and try again. The only drop-in solution I’d come across always seemed to be the Cambridge Soundworks SBS 52. Knowing this would work for the AC, I started focusing on what would fit in the Egret. There were a couple Egret tutorials for full on powered speaker solutions, usually involving modifying the original wiring and shoving in an ugly PC subwoofer behind the coin box. Yech. I didn’t want the cabs to sound unnaturally pumped, I simply wanted them to sound better. The stock speakers in both are actually pretty decent, but the Egret in particular could use a boost.
Cambridge SBS 52 are cheap on eBay so I thought I’d give them a shot in the AC. Removing the housings required a long Phillips screwdriver, with a fifth screw hidden behind the speaker grill. I removed the old solder, brought them upstairs and swapped them with the AC’s originals, using its quick disconnects. Sampling games I was familiar with I could hear maybe a very slight improvement, but the midtones had a kind of boxiness to them that wasn’t so pleasing. Or maybe they were fine and I just needed to give them more time.
I went ahead and took apart the Egret’s factory speakers which took a little more work to disassemble. They have their own brackets and speaker boxes, and their wires were soldered directly on to the driver’s tabs rather than using connectors. It turned out the Egret’s speakers are also 3″, same as the AC, and both are 4 Ohm ~10 watt. So sorta rushing things, I ordered another cheap pair of SBS 52. When they arrived I went through the same process, removing the housings, desoldering, then desoldering the Egret’s speakers, soldering in the new ones, back in their boxes with the bracket and back in the cab.
Since I’ve been playing a lot of DonPachi I threw the board in and played for a few minutes. It didn’t take long to realize it actually sounded a bit worse. I’m not sure how I thought swapping in unpowered PC speakers would be an improvement. I also realized that the Cambridge speakers were actually 3.5 Ohm — probably not a big deal but long term maybe not a great idea. In the end I put the factory speakers back in both cabs, annoyed with the whole project. Anyway, these were never meant to sit in someone’s office, but in cacophonous arcades pushed, by the dozens, side-to-side. This was another lesson in being happy with what you already have.
