For a patio system, powered Bluetooth speakers make perfect sense. Any of the choices in the line of Edifier speakers are excellent. The R1700BT model is hard to beat for that application.
Patio tunes
Hi I'm in quest for building descent patio system and my budget is $500 total
I need wireless bt amp/streamer and speakers. The amp should be portable enough to move it to the outside when nice weather cook-outs going on. I'm not planning to keep amp outdoors, but would collect suggestions here as well as experiences.
