Increasing bass on floor standing speakers


I have some floor standing speakers that were a Visation kit from 30? years ago. 
The treble and mids are amazing but the bass is a little weak. And suggestions on increasing the bass? 
Concrete floor 
Room 3.5 x 11 meters... Speakers on the long wall. 
Rotel ra-01 amp
Project rpm 4 (I think) 
Currently listing to Stevie wonder hotter than july.
Thanks for any suggestions

Do you have another music source to try, aside from the TT?

It could be the TT/cartridge setup.

Also, what cartridge?

I asume that you meant Visaton and if so see if anything looks similar here in order to let us know what general type of speaker you have.

Don't know if it's been mentioned, but you could try placing them on soft footers (I usually recommend first trying something from around the house like cutting up an old mouse pad/rubber mat, et cetera).

Does the Rotel's LF boost (6dB @ 100Hz) help?

As far as moving the speakers goes sometimes just a few inches will make a difference.
