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.

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.
Check out the Nola boxer. If you decide to go with the boxer
you should also get the Sound Anchor loudspeaker stands. This is very important. This combination won "best of show" award at RMAF 2012. It was driven by a Rogue integrated tube amplifier.
