The room is 15x12 dedicated media room and yes it is a closed area, pretty much rectanguler with a small cut out on the sidewall for a bar.
Mostly will be using for home theater set up with a pioneer VSX-LX303.
5.1.4 atmos set up.

My opinion is that you can get a better sub, especially if you're going to be digging into movies with true LFE. That little Tannoy is looking good for a small listening room where you need LF music support for speakers that can't truly hold their own.
Assuming in your case, 8' ceilings, your room is just under 1500'3. A PB1000 would work better for you, I think. PB or PC 2000 would be the way to go, frankly. Also worth considering is Hsu VTF2mk5. The new Speedwoofer (i'm not very familiar with it yet) has been getting some raves and may work well for you.
In the end, any of those should work pretty well as a single sub. I definitely recommend multiple subs because they smooth out your bass response in the room. Either way, taking shortcuts on a subwoofer can leave you wanting more. One good sub is worth way more than 2-3 'meh' subs! Consider: buy the best single sub you can allow yourself to afford now, then if needed, start saving for a second matching one.
