I am not super fimliar with 70v systems. I thought they were designed for places like offices and retail stores that want to have background music and an overhead paging system. Will it be able to produce enough sound for my situation? What's the advatange of this vs a traditional system?
How many speakers would you recommend? How do yo deal with the transformer for each speaker? Does it attach to the wall as well?
Can you still use a volume control for each room?
Again, I can't thank you enough for your help!

In your situation with cinder block walls you will have a lot of reverb problems. I would place a speaker at each stall with a wall bracket. Your ceilings are too high for ceiling speakers.
You can use any speaker you want and might a 70 volt transformer by each speaker, or get speakers that already have transformer.
In your situation I would use mono and not stereo. In your situation that works best. If you want it loud you will need speakers bigger than 4.5 inches.
If you do not use a 70 volt system you will have to use impedance matching volume controls. This wastes a lot of your amp power.
With a 70 volt system you can wire with cheap bell wire and have no losses.
Now you can
distribute power to individual speakers, so some are louder then others.
You take the power of your amp, and the sum of all the taps must equal the amp power, with a fudge factor for losses.
You can
control the volume to each room with a
stepped auto transformer control.
In your situation this is the way to go. It is safe and reliable and will do the job for you over the long haul.
Your volume will depend on your amp power, power handling of your speakers and their efficiency.
If you are not experienced you should consider a professional installer, although working with 70 volt systems is actually very straight forward. You just must understand the really very simple rules of the power distribution by transformer tap.
