Which woofers (B&W/SVS/Other?) and placed where (all corners, back corners, behind AT screen) - choosing the best alternative

[Defrost44]

Smaller room. 11.6ft wide, 17.1ft deep (long?) and 6.7ft high. So app. 200ft2 and 1330ft3. AT screen 2.35:1 filling most of the width. Seating between 2/3 and 3/4 way down - one row only. Budget allows for various options, and I'm considering those available to me in Denmark. Planning for 3 x B&W CT7.3 as LCR and 8 or 10 x B&W CWM7.5 S2 as remaining speakers for my Denon 8500HA in a 7.2.4 or 7.2.6 configuration. The CWM in the Denon Auro3D type setup, as the room height and concrete construction doesn't allow for any in ceiling speakers. The CWM's have build in backbox, and I'll build my own housing to get the angles right. AT screen will only have depth to house the B&W CT SW subs - none of the SVS's.

What do you think I should choose from these, or am I thinking wrong about the subs? Should I consider different brands? My budget for sub allows roughly for these options.
Opt A: 2 x B&W CT SW15(*) behind AT screen (the dreaded Left-sub-Center-sub-Right setting that AudioHolics don't recommend). Cost DKK 35.400,- ($5313) including B&W SA1000 sub amp
Opt B: 2 x B&S CT SW12(*) behind AT screen (the dreaded Left-sub-Center-sub-Right setting that AudioHolics don't recommend). Cost DKK 31.000,- ($4653) including B&W SA1000 sub amp
Opt C: 4 x SVS SB3000. One in each corner. Cost DKK 38.000,-($5704)
Opt D: 2 x SVS PB3000. I fear these are a little too high and will cover the screen, so they would have to be either on their side (can they??) or placed one in each back corner. Is this valid placement? This is the one I'm currently most positive about, also because it might be "plenty enough" for the room size and the cheapest at the same time. Cost DKK 28.000,- ($4203)
Opt E: 2 x SVS PB4000. One in each back corner. Cost DKK 40.000,- ($6003) This is the most expensive, so there has to be gooooood arguments over for instance the 2 x PB3000.
Two x SVS SB4000 would cost app. DKK 32.000,-($4803), but I don't think this is interesting when looking at the other options.

(*) Can't find any online review part from SpareChange youtube review, where the SW15 "weren't slouches", but weren't the best for the price either. B&W unfortunately also only describe FRQ response as -6db from 16Hz to 140Hz. Nothing about the -3db cutoff, that I can find. I've heard them myself in HiFi-klubben here in Denmark, where they sounded fine to me. But I'm not a very experienced subwoofer listener
Alternative placement for the B&W subs could be back corners.

Any tips, recommendations or other comments welcome

What about Arendal Subs?

What about Arendal Subs?

Don't know much about them, and how they stack up against the SVS's. Can't find Danish distributor, and also no place to listen to them - at least when I have looked. They could be something to consider though.

Reviews of their product have been pretty good. I think they are following the ID business model and have shipping and in home trials built into their cost (similar to SVS here, stateside.
Also in Europe is XTZ. BK Elec in the UK.

I would avoid B&W Subs. They are not known for them. Most Speaker manufacturers, really, don’t do Subs very well; they come across more as an afterthought when you see performance reviews and measurements.

Also from previous conversations, I know SVS gets real expensive over there in Europe… just might not be the best value.

Regardless, you can’t really judge a Sub by its performance in a showroom, so not getting to hear it in your room prior to buying isn’t a big deal. In the end, if you can understand the performance metrics in reviews with measurements, most Sub buying comes down to ergonomics… how does it fit your room and system, user controls, connectivity. FR, CEA 2010 BurstTesting, long term compression sweeps and Group Delay tell the tale, and most well designed modern subs do these quite well. Including Arendal.
