And a few others. Most are not Bluetooth.

You have electrical outlets around your yard, but did you install and direct burial speaker wire from your house to the areas where you would like to place speakers?

Generally 14/4 direct burial works quite well.  Most landscape systems would have an amplifier located inside the house or an outdoor utility room where the amp and source, such as a Sonos Port would be located.  Then passive speakers, like you mentioned and shown above could be installed at the other ends of the speaker wire.  These would be systems like:

This system is powered by a Sonos Amp so it might be OK but depending on the size of your yard, it would run out of steam pretty quickly.  The larger systems have dedicated amplifiers and can have more satellites, 2 subs, etc., but the cost much more.

If you can't run wiring to the house, you could install something like this from Rockustics:

This would be installed outdoors, in a weatherproof box, near one of your power outlets.  Then you would run direct burial speaker wire from this enclosure to some speakers like:

The reason for choosing these speakers is they have a compression driver and an 8" woofer making them much higher efficiency compared to the other speakers and that small amp only has 40wpc to work with.  These speakers are rated at 97dB so they will make use of the amps limited capability.

Hopefully that helps.

Thanks so much. So helpful. I do need Bluetooth so I guess I’ll have to do that through an amp.
 

 Oh and yes, I have speaker wire throughout the yard as well! I also still have half of it trenched up lol so I can add what I need! :))

They you just need a passive speaker system with a location for the amp.  Also, if you go with something like Sonos for a source, you don't need Bluetooth.  It runs on wifi which is better anyway.  

If you go with a passive system that includes a subwoofer, which you should anyway, make sure you pour in a bag of pea gravel at the bottom of the hole you dig for the sub.  This will make water drain properly so that if and when the ground becomes saturated with water, the sub stays put and doesn't float/ heave upwards on it's own.

Thanks Paradisecom - do you have any recommendations on specific systems you would purchase? I’m a little bit lost on exactly which items to buy. :(  TIA!

Given your budget, the Sonance system shown above is a good option, especially since it's on sale, now.  

Perfect thanks. And here I thought my budget was good lol lol haha

so I should get that one, I’m assuming it comes with a base speaker, and then I don’t need any kind of amp?
