i dunno if you have seen my thread on the front wall SBA (single bass array), but with grills it can potentially yield the best WAF and best in room response…
Will check your thread out, it’s “Gavin’s build” right?
This one.

Oh interesting, just read the whole thread. Something to consider for my build. Thanks a ton.
You can use thick curtain as divider (place it at open arch there)… open/close so easy.
Can consider stacking it… if room small… but bigger room, 4 corners
Various brands of rockwool. If you are in midst of renovation, it is easier to get the contractor to order for you. For stuffing small walls like this can use 80-100kg/m3 density.
If you have any drop plaster ceiling, it is important to stuff with rockwool as well. Doesn’t need to be very dense or heavy, it just helps to damp any vibration. Usually the vibration and debris in the ceiling is what causes the rattles.

4 corners is out of the equation for me, 1) Left rear corner has a door leading to MBR, so no go for Subwoofer there. 2) I think 4 subwoofers on the floor won’t pass WAF 
I will probably start with two physical subs on the floor, will experiment front 1/4 & 3/4 wall VS diagonal corner (front left and rear right). Maybe might push for 3 subs down the road if WAF warms up to HT setup after few months of using it.
Yes, I am in the planning stages of reno, discussing with IDs/contractors now.
I do have drop ceiling and was thinking about acoustic ceiling solutions, they cost a bomb by the way. Will highly likely go with normal plaster ceiling with rockwool stuffing, that seems to be the most economical option. Came across this TIMBERIX ceiling solution and contacted local dealer (aralad), they quoted me $S16K for microperforated TIMBERIX panel supply & install with 60Kg/m3 rockwool solution for my 5.1m X 4.8m ceiling.
There’s a new material - combination polyester felt with wooden slats.
Looks very simple but it is actually very innovative. I haven’t been able to find a source anywhere…
It really transforms a bare looking space…
Installation in progress
Boom!
You could use this as a finishing over rockwool, to increase the lower end absorption over just the thin felt.

Wallhub Singapore has them, I have them as an option.

Have you confirmed on the 2x rel HT1003?
Thinking about it, the subs likely the first limiting factor in terms of output for the space.
Or course this is totally subjective. But worth a thought and perhaps move up to a pair of 1205.
Hmmm something to ponder indeed. The 1205 MkII aren’t that much bigger either, will consider when the time comes.
