Far too busy trying to have a system people might think is cool. Ditch the Io and that belt driven nonsense for a start.
And then there are those hideous speakers.
Then youâre not really toyboy material then 
And bmtell is?

Concrete floor, and what of the walls are they brick/block or timber stud? And the ceiling?
If itâs bass resonance issues then foam panels is not the answer.
1st step is to locate the speakers and listening seat to best avoid standing waves, next step is LF absorption, which are often triangle items to go across corners.

Itâs a flat roof extension with brick walls and patio door at one end. I canât really alter the listening position. The speaker s fire across the room which is quite narrow so Iâm limited with how far they can be placed away from a rear wall.
sub 200Hz the roof and patio doors should offer some absorption, but the rest will be non-absorbing, so there is a chance you are getting LF energy build up as the modes wont be absorbed much
If you cant move the speakers, then you either need speakers which donât excite the room modes, a bunch of LF absorption, or digital box to notch filter the mode frequencies down.
if the speakers are along the long wall, try this as a quick and dirty test.
- measure the length of the wall behind the speakers - corner to corner
- work out 23% of this, and move the speakers so the centre of the bass driver is this distance from the outside wall.
if they must be backed against the wall, then you will get room gain, otherwise try pulling them out to 23% of the length of the short wall - again measured form the centre of the bass driver.
its a quick and dirty way of finding a reasonably benign location for the speakers. have a listen and see what you think. if there is an improvement, you know it is room modes and not speakers.
for LF absoprtion you would need something like these in the corners:

or possibly the tube traps MAX is selling off

if you want to go DIY then a tuned panel absorber is the way forward
best of luck

Have these made any difference?
Yes - the speakers have just toppled over and now they donât produce any sound so the bass issue is resolved - Yay!!
I did think it was a bit early in the year for spring.

Hard to say but I think so however it doesnât resolve the issue at specific frequencies. I need time to experiment a bit but too much work on at the moment.
I have an xtz room measurement thingummy if you want a borrow.
