Looking for a good speaker system.

You would likely be better off getting a wifi receiver to drive the speakers. Yamaha makes some good network controllable receivers that can stream music from wifi or Bluetooth.

If you were looking to signal each speaker via Bluetooth or wifi then only 1 speaker would work per source, AND they would need their own amplifier and power source for each speaker. Running speaker cable from a receiver to the speakers will be much easier/better overall.

Your needs are very unclear. First of all we don't even know how many speakers you want, nor do we know if these are supposed to be in one room or multi-zone setup throughout the house.

If you're renovating the house you're far better served getting some in ceiling speakers like these:

And then wiring them to a SONOS connect

That AMP can run 4 speakers if you run them in series, or buy this:

And connect it to a nice 4 channel amp like this:

Yeah so then definitely follow my idea, you will get good solid power out of the speakers, and all the connectivity you want by using the sonos. Personally I would do the Sonos Connect and the amplifier I mentioned with those 4 JBL speakers. I have them in my house they are great. Wire each speaker to the speaker outs of the amp, and then connect the sonos to your network and an RCA cable from the sonos to the amp. On the back of the amp is an auto on switch which allows the amp to switch on and off on its own depending if it gets a signal. So you can hook this all up and control it right from your phone, from the SONOS app.

You don't need a subwoofer unless you really want one, if you do you can hook it to the line 2 out from the amp via RCA cables. IMHO its not worth it.

EDIT:

if you don't have a flat roof check out these:

And then just use wall mounts and run the wiring to the amp across the tops of the beams and then through the wall. If you want top double the speakers you can get a second amp like the one I mentioned, run the SONOS connect into the line 2 in, then the line 2 out of the amp to the line 2 in of the second amp, now you have 8 channels off your sonos.

Wall mounts such as these:

Want to bump?

2 of these:

And 4 pairs of these:

Controlled by the SONOS i mentioned earlier.

Yeah you can just turn off the amp to those 4 speakers manually. If you wanted to go fancier you could run 2 SONOS boxes 1 to each amp, as the app allows you to sync or seperate the signal they are playing so you could just disable the one you don't want playing.
