Upcycling speakers Answered

Hi all! I came across an old aluminium briefcase (the kind you'd transport a million dollars in if you were a spy), and I was thinking of converting it into a battery-powered multimedia platform. Details aside, the first milestone would be to make it into a glorified bluetooth speaker.

Now both as concerns for the environment and my own wallet, I plan on reclaiming components when I feasibly can. Bookshelf speakers (with no amp) tend to go for really cheap in second-hand stores where I am, so that's my starting point. The plan is to open up a pair of speakers and attach them to the case somehow, with a wired power source and eBay amplifier circuit to begin with.

So my question is, what's it like re-using bookshelf speakers? I know there's a lot of projects online converting them to battery power, but what if I open them up and take out the actual speaker inside? Are there any issues, or much loss of sound quality when the wooden case is discarded? I'm no audiophile here, even a fuzzy sound is okay as long as it has a bit of bass to it. If I use it a lot and I really have the chance, I'll buy a proper pair of speakers to replace the older ones (and maybe consider proper audio engineering where I route frequency ranges to different woofers etc). But that's not happening right now!

If anyone has experience with this kind of project, any advice is appreciated :)

And if anyone's curious, I was planning on bolting the speakers directly onto the front of the case (which is solid plastic), allowing it to be used closed or open. Then add Bluetooth support and eventually a Raspberry Pi with a HiFiBerry card, then with cool mini MIDI controllers the sky's the limit.
