Current setup i can feel the floorboards vibrating, so i assume that theres not much i can do in that aspect.

 

If its being transmitted down your stands, best you can do is sitting speaker stands on two layers of 600mm by 600mm concrete pavers to add some mass, with some matting under the concrete in the corners onto the floor. The comparably flexible floor has derrated the stiffness of your stands. Stands that aren't sufficiently rated can reduce base. Whether its from the floor radiation giving cancellation or speaker movement relative to the driver, I'm not certain. 

 

But everything vibrates to some extent from acoustic loading. Eg I can record conversations of people in a room with an accelerometer on a ground level concrete slab. If its vibrating from acoustic loading, then it is acting more as a panel absorber. 

 

Although if its this dramatic, gut feeling is its positioning in the room. I'd start by saying stuff aesthetics, just see if you can position to get the sound back, then go from there as at least you have some direction as to the issue. Perhaps do some tones/sweeps to see of there are any big holes that change with speaker and listening position. Then at least you know its a room response issue, and you could then treat to the problem.

Previous house was double brick and concrete slab, and even though it had a tile floor, the depth and response of the speakers was substantially better.

I have a lightly constructed room also and keeping bass in has always been the biggest issue... 

 

A big pair of JBL's is the only way I can get decent bass in my room. I have had some success with Sonus Fabers in my room but even my Duntech Sovereigns struggle to make bass, it just disappears.

 

My experience has been different.

I love lightly constructed rooms from the perspective of managing "in room" bass - they're significantly easier to get the bass right, as all the low bass leaks out instead of bouncing around the room creating long decay times.

 

Of course a lightly constructed/leaky room isn't so great for other house occupants and neighbours - but from an "in room" bass perspective only, IMHO a lightly constructed room that lets low bass out is vastly superior to a more acoustically rigid room that keeps bass in by reflecting it off the boundaries.

 

Well mixed outdoor concerts achieve wonderfully dry non-reverberant bass - clearly impossible to replicate in our small rooms, and the more rigid the room boundaries, the more the bass bounces around taking ages to decay

 

@kelossus bass doesn't disappear - if your speakers produce it, you hear it - and if it decays immediately, that's gold, as it's not bouncing around the room!

 

I cross between my TD18s and sub at 60Hz - there's not much going to the sub, and the TD18s produce amazing tight/dry bass in my lightly constructed room.

 

cheers,
