What is the pool house like? Open closed? If this were me I would do 2 zones. A pool house zone if under cover and a around the pool zone. That way you can control the audio in both sections. If you have 1 zone for the pool it might have to be too Lou day for the people under pool house and vise versa. Speakers just in pool house might be too loud for people in pool. I would do your setup like I did mine. I have 4 inceiling speakers in my pool house on 1 zone. Then I will have an array around my pool. It’s own independent zone. And my covered patio also has 4 speakers which is its own zone. That way I can balance all my volume so if people are in pool house pool and patio. Just how I usually design out setups. I like a lot of zones for proper control.
I have posted many times about different arrays. Pretty much the dealer you deal with with be in 1 of the camps of sonance, niles, Russound, Nuvo, triad.
Triad and sonance is nice cause they have matching amps. Nuvo is nice if you team it up with a Nuvo player cause their players can power their full 8 speaker array. Nuvo players can also power 4 speakers. Sonos players can only power 2 speakers but I think they have a larger amp player out there now. I don’t know.
The monoprice setup Brian found is pretty interesting for the price. I just bought my buddy’s shop a pair of monoprice speakers. Little 50 dollar bookshelves and we still can’t get over how clear and loud they play. Will be interesting to see what Brian thinks of the array.
