I'm looking to connect my phone/tablet/mp3 player to multiple speakers to play around the house. Is there an app or do I need to get a hub and connect to all them?
I can think of two very real solutions, one of which i've used and the other a very popular solution. First you stated you wanted to connect using your phone/tablet/mp3 player - so going with that premise the suggestions below based on a Mac, while cool and useful - don't meet your requirements like the following:
BLUETOOTH: There are speakers from Ultimate Ears that are pretty popular called UE BOOM. They have 3 "flavors" that can do what is called Party Up Mode. They are the UE BOOM, UE BOOM 2 and UE MEGABOOM speakers. The really cool thing about Party Up Mode is you can add up to 150 speakers together and control them from one phone. I have 2 of the UE BOOM 2 speakers and pair them together and it is actually very cool. I do need to put a caveat in place - they aren't always without glitches, but when they work i freaking love it. The range is decent. I know that the speakers are the one that create the "network" to talk to each other so i'd assume they can stretch out pretty far away from the source as long as the main speaker that is Bluetooth is close. Hope this makes sense. Oh, and they are waterproof, etc.
Cool video showing many connected together:

WIRELESS: The other option is Sonos, which is a very popular solution and it uses WiFi to connect to your phone, but if you connect one of the speakers hardwired to your router it turns the Sonos system into a Mesh Network, which means instead of getting the connect all from WiFi they are linked together, which is a more elegant solution in my opinion. You can add all kinds of different sized speakers for awesome sound, even linking them in stereo (which the UE BOOM does as well when 2 are connected).
Because it isn't Bluetooth it isn't dependent on the phone so phone calls wont interrupt it, you don't need to turn the phone ringer to vibrate to keep the music from cutting out, etc. Plus you have a ton of services from Sonos that are pretty cool. I haven't played a lot with them, but I've researched them a lot because i really want some!
