A Bluetooth speaker that sounds really great?

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.

I have the JBL Boombox 3 WiFi Wireless Bluetooth Streaming Portable Speaker and it is outstanding !   When using wifi, you can stream Hi Rez to it.  Battery last forever, and there is nothing louder, and with more bass.  It is a little heavy and big, but, the sound is outstanding.  Note: With WIFI, the JBL app supports the streaming services like Qobuz, so, you can use your playlist in the JBL app and stream HI REZ, otherwise, you just use Bluetooth resolution to stream from any app. 

+1 on JBL Boombox portable wireless blue tooth waterproof, cary it anywhere, yard work, garage, around the fire, down on the dock   Holds charge for days and days.

Get the big one, Boombox 4 is current model.   They go on sale for -100 often.

i have a small one for travel.

Sonos satellites and sub move in and out easily. We do it all the time when bbqing. Plenty of fidelity. Sub adds icing on the cake and easy to grab with one hand. We also have the big JBL disco boom box with the stand and microphones. More for the kids and karaoke and can blast from 50 yards away. Not my cup of tea. 

I really like my ultimate ears wonderboom.  It is surprisingly musical.  I tried using two for stereo, but actually, listening to one alone sounded better. Strange. It only does Bluetooth, not Wi-Fi.
