Better sound, better speaker

So I know most folks are happy with the default GB speaker, or that one from Adafruit but how about a REAL speaker? I've had these ones for a while sitting in a drawer and decided to see if I could make it fit in the GBZ: https://www.parts-express.com/dayton-au ... m--285-103

It's got a rubber surround, metal diaphram and an actual spider. Frequency range goes down to 240Hz as opposed to the 600Hz for the Adafruit one. It does sound a lot "fuller" compared to the tinny sound of the built-in speaker. The only problem is that it's a little thicker than stock. Okay, a lot thicker:

Plus the mounting bracket is square and not round. A little help from Mr. Dremel takes care of that problem:

And after some polishing it fit right into the existing speaker bracket:

I haven't fully removed the battery compartment yet as I'm trying to make the minimum number of mods to the case as possible, but this larger speaker definitely requires some cuts so I took it to the drill press with a 1" bit and then massaged it in a couple of places with the Dremel afterwords:

I don't have my button circuit board yet, so either that'll require some modification or it might turn out there just won't be enough room for a speaker this large. But as of right now it's fitting great!
