Try before you buy. They are on display in every HIFI shop. somebody before was happy with the sound of Bose Soundbar 700 + Bose Bass Module 700 + Bose Surround Speakers -$2600

PMCs are not just good speakers, they are excellent. PMC ceiling speaker cost $1890 each, so not particularly cheap.

Sound separation walls are explain on CSR gyprock website, but I wouldn't go with that internal frame, the room is not that big. Try to use acoustic insulation between studs and 2 or 3 layers of plasterboard or firecheck. PMC are quite famous of having high level of details. With good amp just those 23s can fill up your room easy with music. I would go with PMC only and 5.1.2 maximum (including PMC centre and 2 ceiling). If you ever try power amp and set all speakers to large/full range you might want to sell subwoofer. Those PMC have strong and deep punchy high quality bass (with good power amp).

He's saying that setting it properly might take few days or weeks + a little bit of patience. Look up SVS website. 'The crossover frequency of your subwoofer is the frequency at which your speakers start to roll off and your subwoofer kicks in with LFEs and bass notes. Most modern AV receivers feature an auto EQ program that will assign the proper crossover frequency automatically based on the capabilities of your loudspeakers. It’s generally best to leave these settings where they are. If you’re using an AV processor, preamplifier or a DSP subwoofer to adjust the crossover frequency in a two-channel or surround sound set-up, here’s a few tips to get the best performance possible. As with any bass management functions, it’s helps to do some critical listening and experimentation to achieve the best sounding results. If you know your speaker’s frequency range, set the crossover point roughly 10 Hz above the lowest frequency your speakers can handle cleanly The most common crossover frequency recommended (and the THX standard) is 80 Hz. The numbers below highlight general guidelines for speaker/subwoofer crossover frequencies On-wall or Tiny 'satellite' speakers: 150-200 Hz. Small center, surround, bookshelf: 100-120 Hz. Mid-size center, surround, bookshelf: 80-100 Hz. Large center, surround and bookshelf: 60-80 Hz. Very large center, surround, bookshelf: 40-60 Hz. Tower speakers with 4”-6” woofers: 60 Hz. Tower speakers with 8”-10” woofers: 40 Hz or Large/Full-Band (i.e., full-range). If you’re unsure about your speaker’s ideal crossover frequency, try our SVS Subwoofer Matching Tool, which will recommend the ideal SVS subwoofer for your speakers and tell you the best crossover frequency. Listen for a smooth transition between speakers and subwoofer. Ideally, the blending will be so seamless, you won’t be able to localize the bass and everything will play in unison. If you’re noticing a bass bump at the crossover frequency, try adjusting the volume control to match the output of your main speakers. For a deeper dive into crossover frequencies, check out our Digital Bass Management Primer. "

It's not about the price, selling doesn't go that fast here.

So soon you will join our Focal owners club. Arias 936 are standing in my room so I know why you like them.

So you moved it to centre and run calibration again and than it's quieter than you previous speaker or setup? Maybe try manual level adjustment.

The problem is that you have 50m2 to fill up with music so those Excites might be too small. Also I think the combination of Rel + MF for metal and classic rock may not be the best solution. That Rel is rather smooth than punchy and probably too small for your space. MF is also smooth neutral , so I would say it's more for slow jazz, vocal, blues. Audition necessary like always. I would consider higher model of subwoofer, maybe (T7i). There are amps with good DAC and streamers build in, something like Naim, Primare or Hegel.

I would say Dynaudio Evoke 20 would be better for your space.

I don't think so your AVR has pre outs so it would be difficult to use power amp anyway.

Freya has great reviews, but matching integrated with speakers is complicated enough for me. I would try some integrated in$4000 - $6000 area.

Which Arias do you have in mind? I think Arias were made for amps like Naim (Focal and Naim are one company now). It doesn't mean that Naim is the best choice for Aria but it has a rely good control over those speakers. There are few other options for Arias on the market as well. General rule is to get speakers first and then amp unless you already auditioned Arias with Naim.

I would move sitting position to 3.5m or even 3m. Also I would skip projector and investment all $12k in speakers+ AVR. 5.1.4 is enough or even 5.1.2 - quality over quantity.

Definitely run cables before plastering.

it's much faster and easier to get it custom made (the stand) me think. You can even get a bench top from Bunnings and cut it to suite the TV and speaker. Alternatively any carpenter or joiner can do it for you.
