1) Do you have outdoor speakers at your home? If yes, how do you get music to them? Can you control the volume and source while outside?
No -- I use a self-powered "portable" speaker that is sourced wirelessly from my receiver. I can control the volume but not the source itself (have to go inside and change the source on my receiver itself).
If no, why not? (e.g., not necessary, can't make it work, etc.)
Having dedicated outdoor speakers just hasn't been a priority for me...
2) Please choose and rank the top 3 most important features to have for outdoor speakers (1 being the most important):
1. Ability to adjust volume without going inside your house
2. Hidden into decor or landscape
3. Sound quality
3) Do you have a power outlet on your deck or patio?
Yes
4) Where do you have /or would you want outdoor speakers? (e.g., deck, under an eave, in the garden, around pool, other, etc.)
On my patio, probably mounted up near the roof.
