    there is another guy that did one similar, but without the tangband.

    I have the 2inch sub and matching PR's, just cant fit all the pieces of the puzzle together at the moment

    I have thought about that too. It occurred to me that a cheaper rather than more expensive set of ear buds would probably be better, since they are less likely to have any system specific DSP applied.

    I think about that video all the time. I keep thinking I need to try it.

    Maybe not Hi-Fi enough for us 'speaker types' but here is a YT video I remembered watching where the DIY Perks guy turned old earbuds into a bluetooth speaker.

    BTW, I purchased another BT speaker recently, the Stormbox Micro 2. This one's more of a clip-on personal BT speaker, rather than something the size of the Wildbox. It's truly amazing what they've managed to squeeze out of a 2" speaker in a gnat-sized box. And 10W of power - that's likely more than my old Sanyo massive boombox was able to do - both channels.
    Perhaps a well calibrated piece of fabric in front of the tweeter?

    Thinking about the firmware and its EQ settings. I'll bet it's borderline machine code. The thing is, what we think of "+3 dB boost at 500 Hz" or whatever needs to be translated into a filter, which basically is a big pile of math. I imagine the math was done earlier on, and then that generates a bunch of code which constitutes "a filter," which is what get saved as the firmware file.

    I could be wrong, but it just seems more likely that the more human-understandable stuff happened further upstream. OTOH, if we were lucky, it would be like reading the config for Cisco IOS device. Like, everything you want is there, in human-readable language. ¯\_(ツ)_/¯

    Might be able to build one cheap enough. If you go amlow powdered CSR or qcc by module you can hook it up to a PC and modify eq and other settings to make a.bass shelf.

    Not what you asked, but it's what I've been going for fun and cheap enough

    I downloaded it and tried to open the .FW file once I read the instructions - looks like machine code - not likely to hack it.

    Maybe someone smarter can tell us more?

    I tried that - Notepad wasn't very happy trying to open it at all, LOL.
    I think I was hoping too much that it would be something like a simple INI file...

    At 3MB, the file's a bit too large to load here, but it can be downloaded from the Support link at the Mifa site, www.mifa.net.

    Can you open the config file in notepad or some other text editor?

    The last firmware update that I loaded on the Wildbox boosted the treble a bit too much for my liking, so I was wondering if it was possible to hack the firmware to undo the boost.

    The Wildbox goes on sale from time to time and can be found for less, and is comparable to the JBL Extreme, which costs significantly more.

    I did purchase it with the idea of enjoying it for awhile and then moving the electronics, etc. to a DIY enclosure, but the damned thing sounds so good (with a bit of EQ on my Android phone) that the only real "hack" I've done to it is to add some polyester fiberfill damping behind the bass drivers. I also did some measurements of the Wildbox - see here : The Subwoofer DIY Page - The Mifa Wildbox (diysubwoofers.org)

    What about the firmware are you trying to hack?

    I'm not sure if I'm following you exactly, but I think hacking bluetooth speakers all the time. Or, at least being able to salvage the bluetooth/amp portion of them. I keep hoping to find cheap ones worth ripping apart. I hadn't heard of the Mifa Wildbox, so i looked it up. It's a bit more expensive than I was expecting. Honestly, in my mind, once the bluetooth box costs $100, it's too good to pilfer for parts. Like, I've hard some bluetooth mini speakers at this price point that, honestly can be pretty darn good. (I still use a Sony SRS-X33 that I got like 7 years ago--it travels with me in my laptop bag. I think the retail on that was like $100-$120 when it was new.)

    If you do choose to hack the Wildbox (or any other bluetooth speaker), please keep us posted. I'm very interested.
