A Bluetooth speaker that sounds really great?

Carz;  WHICH JBL speakers? They only make like 4 of them !

I think you can link the JBL stuff also for stereo. 

I like the Marshall offerings.

You didn’t mention a budget, but Edifier and Audioengine both make fairly highly-regarded and budget-friendly Bluetooth speakers.  Here are e couple examples but both make higher-priced models if you can spend and/or want more.  I have the Audioengine B2 single Bluetooth speaker and it sounds quite good.  The Edifier uses LDAC and the Audioengine uses aptX HD and not sure if you have a preference.  Hope this helps, and best of luck.

Soix; these options will be great in my man cave. but I need something a little portable and cased better for time outside. I will check these out regardless.
