Hi,

I’m planning an audio setup for my living, dining & kitchen open space, which you can see on the plan and the 3D sketch above, with the measurements.

I was thinking to install Sonos architectural speakers:

 - 2 pairs of Sonos In-Ceiling 8” for the living and dining area (vaulted ceiling) and

 - a pair of Sonos In-Ceiling 6” for the kitchen area (flat ceiling).

Each speaker will have a dedicated ceiling-box it will be installed in and all 6 of them will be connected directly to a single AMP with a Helusound 400 2x2.5mm2 cables.

I read in Sonos guidance that the Trueplay won’t be possible if there is a mixture of speakers connected to the same AMP, which I’m planning to use here. I’m considering changing a pair of 6” to 8” but it may be an overkill for such a small area.

Speakers in these areas will be used for music only. Having a separate TV room for Home Theater setup.

Here are my queries, hope you will be able to help me or point me to the right direction on:

1. Would 2 pairs of 8” be enough to cover the living and dining area, and another pair (6” or 8”?) to cover the kitchen?
2. If I go with 6” in the kitchen, would it be better to go for a second AMP so I can have Trueplay enabled for the 8”s?
3. Where would the best place to install pair of speakers in the vaulted ceiling - in the middle of the slope, closer to the walls (lower position, speakers of the pair further from each other) or closer to the top of the ceiling (higher positon, speakers of the pair closer to each other).

Thank you for any comments and advices.
