Very interesting , my aproach for what iit's worth , it probably has
some flaws.

Damping the room enough to,get rid of flutter echo ( the garage / cave
sound ) using some odd bits of acoustic material , mostly behind me I'm
sitting close to the back wall .

Use digital room correction for the bass , built in DRC in my
pre-processor .

Speaker placement L,R placed at 1/3 and 2/3 of the lengt of a long wall
in my rectangular room 1/5 of the depth out in the room.
Some fine tuning by ear mostly the angle inwards the listening position
.

Centre is in the middle but at ear high when I'm sitting in the sofa
,65" plasma above centre speaker .
Many have the centre very close to the floor this sucks midrange gets
really coloured .
I listen a lot in Meridian trifield mode actually using all 5ch for
stereo music .

Subwoofer at 1/5 of depth and length not in corner , probably a waste of
capability but excites less modes .
Low xover frequ to sub 50-60hz using the pre amp processors fillter .

Note sub is also filtered by the DRC ! This i think is essential for
good one sub integration the DRC makes it really gel together .
But xover must be at low frequency and main speakers must be able to
reproduce some bass . Xover filter must be steep

I don't think you can integrate to small main speakers with a single sub
xover would be to high and you need 2 subs close to the speakers , in
many cases I've heard the xover is a bit on the high side and sub still
has audible contribution at 2*fs and as the sub is not perfect it also
does other things like port sounds .

It still not perfect but very good but even better bass I need bigger
main speakers and 2 or more large closed box subwoofers :)

I imagine there is a lot of improvement to do to my aproach :)

Where is 1/3 coming from ?
I noticed that many speaker placement softwares simply suggest a grid of
positions at odd multiples of room dimensions they often has 1/3 near
the top of the list .
There is quite a lot of them so it may be hard to try them all manually
.
But a room has many other constraints it's a living room with furniture
and doors opening and windows , this often means that the side of the
room where the speakers will be is " given " and possibly also where the
sub will be .
