Suggestions for rebuild/upgrade of Smartwood Quaterwave radio

[jbraveman]

I purchased this Bluetooth capable speaker a few years ago as part of a kickstarter and never ended up using it. The sound from it was muddy and the wood finish was too yellow. I have been wanting to refinish it and upgrade the internals/drivers for better sound. My goal is to have a Bluetooth capable speaker with decent sound quality (similar to the Logitech boom or other higher quality bluetooth speaker). It would be used in an office or kitchen.

I’m looking for suggestions about what to put in it. Specifically speaker drivers and amplifier. I have experience soldering and have put together a bottlehead kit in the past (crack preamp). I would prefer something that comes in kit form and has detailed instructions. Speakers have to be 2.5 inches.

Thanks for any suggestions

bt module - 1
or
bt module - 1
Amplifiers .... for this one I would choose some chip based designs, LM1875 comes to mind. Buy pcb from ae or ebay and order original parts from digikey/mouser/farnell
pcb something along the line
or
D class TPA3116 based.
power to the bt module should be fed through isolating dc-dc for better results
something like so
or preferably something out of this list
speaker drivers a bit more complicated given the size and the fact that they need to be wide range. I assume that is a 3" driver or it is 4"?

Thanks for the suggestions. It’s a 2.5” driver.
