Comiso are producing a very nice, quality sounding bluetooth speaker for £59.99 on Amazon, which I’ve had a listen to. “COMISO 30W Bluetooth Speakers with Super Bass, Bamboo Wood Home Speaker with Subwoofer, Up to 20 Hours Playtime.” 

If you want a cheaper option you cannot go wrong with this one from Anker, which I used to have. Incredible sound and quality for £16.99. SoundCore Mini. It’s small but it has good clear output and quite good bass, compared to my more expensive Blaupunkt.
