Bluetooth speaker upgrades

[.d7]

Hello all,
I'm looking for some advice on what drivers to buy as replacements for a portable Bluetooth speaker I have. They are 1-3/4" 4 Ohm 3 Watt drivers. Does anyone have recommendations of full range drivers at this size?

Tang Band W1-2121S perhaps?

Hmm, if they're rated for 6 W would the 3 W from the current system would be sufficient to drive them? I would have to check if the current system is pushing over the 3 W the current drivers are rated for.
