above taken from https://www.loxone.com/enen/kb/tree-turbo/ so in my above example i can have the 3 rooms with 1 master speaker in each (with 1 or more client speakers connected) and then up to 7 stereo extensions (i have 4 already in the rest of the house with speaker cable already run) so i have plenty of room on my existing audioserver.

@joth i've just been reading about the whole master/slave thing. can you confirm something for me please. it looks like if i want to have speakers in 3 rooms in my basement i can have master + slave speaker in each room and run them all from the audio server tree turbo and 24V supply and i don't need extra stereo extensions for this? and each 3 rooms can run different sources at different volumes etc? so it basically reduces the need for the stereo extensions? and seeing as the stereo extension costs the same as a 7" master speaker it's like you get the speaker and the extension all-in-one? am i missing something? it seems to be too good to be true!

i've not used the master/slave loxone speakers. i have the audio server and my speakers will be passive so it's just a speaker cable from cabinet (assuming i ever get around to fitting them!) i'm sure someone will be along soon that has experience with those speakers. @joth and @Rob99 are both Loxone installers so might have some experience.

is that the one-way distance or round trip? according to the calculator i used they calculate on a one-way distance

So that’s 200W for 4 channels, so 50W per channel = 2A at 24V According to https://www.12voltplanet.co.uk/voltage-drop-calculator.html?srsltid=AfmBOooS_T6EeoNwm4mKssOsB77oXk5xoEFFhkeRZ4YgNKtO_lWPu_1X a 15m one way distance 1.5mm cable is sufficient.

It’s probably more the voltage drop at 24V over 20m that’s requiring the larger cable

Sure. But can I still use 12.5mm plasterboard with no top and bottom channel? I’m not sure of that as the white book doesn’t say it’s possible.

That is wonderful information!! I didn’t know that. Didn’t see anything in the white book either but I guess it makes sense. although I’m using 1800mm x 900mm boards so 400mm centres don’t work for me! 🤦‍♂️

Nope. Sign off already done.

Yeah. I’ve done the gypliner system without issues, I just wanted to try something different and cheaper as you’re not having to pay for the top and bottom channels and the brackets. but any savings will be wiped out if I have to use BG products as they’re twice the price of the alternatives

for my next walls I'm thinking of using the DriLyner Fix system as specified in the BG Whitebook. https://www.british-gypsum.com/documents/white-book/british-gypsum-wb-drilyner-fix.pdf this uses MF10 channels (https://www.british-gypsum.com/products/metal-products/gypframe-mf10-channel#standards) bedded in to dabs of adhesive. I'm struggling to find alternate manufacturers (as BG are stupidly expensive) for this sort of channel that can be bedded in to adhesive rather than fixed using GL2 brackets. anyone know of an alternative please? @nod will probably just tell me to dot and dab but I don't want to do that as I'm very very slow and by dabbing the MF10 channels to the walls I can do bits at a time and then plasterboard at my leisure!

totally different experience for us with Wren. very happy with the whole process and the support we've received.

Have a word with @Pocster as he has a grid tiled ceiling and says modern tiles look nicer than the old ones and might be able to suggest new tiles that don’t look as bad.

nice! welcome, congratulations and good luck!

I think we need to be a little bit. SWMBO thought me a little bonkers when I would vacuum in the studs before putting insulation in.
