Mass Loaded Vinyl (MLV) Acoustic Treatments - A Question

MLV comes in different thicknesses, from thin drapes to sheets inches thick

At this point in time - I have installed a vinyl roller blind that is very effective at preventing reflections and because it is installed at the ceiling-wall boundary, also traps/disperses reflections there - a bonus!

But unfortunately it is not effective are preventing the very low frequency "bass blooming" I am currently experiencing.

From what I have read, my room is the ideal size for the propagation of low frequency standing waves- 11.5' x 15' x 8'(high) 

So I was wondering if anyone out there had used the thicker versions of MLV in order to curb bass related issues and if so - what thickness did you find effective and how did you install it?

My system resides in my Living Room, so I am trying to "limit the visibility" of any device I install, either by design or concealment.

Many Thanks

I rarely post here but seeing that this is right down my alley, I thought I'll chime in.
I've been in the Industrial Acoustics field for almost 20 years and in my experience the best product for low frequency attenuation is Rockwool.
Fiberwool would be the next one, foam being the least effective among these three but does work once the density is suitably high.

I've treated my room accordingly and the sound is absolutely fantastic.
I will add some pictures of the back wall, to my virtual system, to try and show what I'm talking about.
Wooden diffusers have also been used to a great effect.

I don't think MLV would help in taming low frequencies

I'm not an engineer, just someone who's in the business of manufacturing Sound Attenuated Enclosures.

Apologies if I came across as condescending, just that I'm not used to writing here, prefer reading.
