Increasing bass on floor standing speakers

Thanks for your reply. 
It's a kitchen and lounge long room with a hallway door at the other end from where I listen. The speakers are set up on the long wall 2.1metres apart starting 1.6m from the corner of the room. I sit opposite them 2.1metres away. 
Yes it's a relative thing... Too much mid and highs for the bass. Just using my ears to assess this and comparison to some tannoy m1 bookshelf speakers. 

Double check and make sure the speakers are wired in phase, using appropriate size cable. Move the speakers closer to the walls or corners.

Walls. Proximity to walls is the single biggest factor. Both for the speakers as well as for you. Speakers back against a wall and near the floor with you sitting near a wall, that's about as much bass as you're ever gonna get. Usually people prefer to move them around trying to get smooth and even, and for that it helps to bring things out into the room more.  

Another thing, what I described is very general. But bass isn't one thing its a range and a room isn't one thing either there's different shapes. It may be you are sitting in an area of suckout or cancellation. So try listening closer or further away if you can and see what that does.

I wrote a lot about getting more bass here:

Thanks everyone... I've got a few things to try. I noticed that the cable used to wire them was pretty thin so I'll fix this up when I check if they are in phase or not.
