Can room treatment improve bass accuracy?

Most of us can agree that a big part of a highly enjoyable system is it's ability to produce accurate, tight and full-sounding low bass. In an attempt to squeeze more bass out of my system I am considering making room changes. Looking for suggestions and comments on my considerations.
I am considering using a large amount of material through out the room that will absorb low frequencies therefore limiting or greatly reducing reflective low frequencies. Will this help and any suggestions on which materials will work best?
Also I would like to enclose the sub-woofer in a Five sided box with the one side that is open facing the listener. This box will be made out of material that has low resonance characteristics. It will reflect the sound waves toward the listener and not the back wall or side walls. Wondering since the box surrounding the sub is so near to the sub how will this effect the listening experience of bass. I expect the box to be heavy so that it will be solid and highly reflective of low frequencies and it will be suspended therefore avoiding transmission to the floor.
Would like to hear suggestions and comments. thanks

I found Ethan Winer's RealTraps, which uses solid fiberglass panels, to be very effective in cleaning up muddy bass in my listening room.

The open baffle subwoofer idea sounds like a nonstarter to me, unless the baffle is 8 ft. x 8 ft. You'll get almost no low bass because the front and rear radiation are going to cancel at long wavelengths. You'll end up with an inert, five-sided room divider with no extension below 100 Hz.
