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.

THANK YOU ALL on your opinions.
I narrowed my choice to the Carbon 7se and the Proac D2.
Mr.Fritz confirmed that Carbon 7se would sound nice with the
NAD. How about the Proac D2, or should I stay away from the
Proac since they require more powerful Amplifier.
You might have enough power, but the Proac's deserve a much better amplifier...
I have a 12' x 24' living space and the Wharfedale Jade 3s fill that room and have amazingly deep bass. They're pretty much like a sealed design and very easy to place. Also a very neutral speaker, if that is your preference. Good luck.
Have you considered the KEF LS50? I heard these at AXPONA this year, pulled very much into the room and they produced nice bass. Here is a video of the setup I listened to - not for the sound, but to show how far they were from the rear wall and still had nice bass.
