Bookshelf Speakers with the decent bass

Looking for the bookshelf speakers with the decent bass that would sound nice in 17'x 12' room. Listening preference:
Smooth/Uptempo Jazz; Acoustic Jazz and Ambiental music.
So far I am using Focal 807W Speakers and the NAD C356DAC.
Good sound, just missing "that" lover bass (hate sub woofers).
I really like how NAD sounds, especially after I replaced the
stock Pre/Amp jumpers. Nice open highs.
Or, should I try Floor standing speakers. Thank you in advance
on yours opinions.
