NAD c270 bee Lack of bass

[mel_valkeneers]

Hey , so i have a little problem ...
I recently bought a set of b&w 685 S2 speakers , they sounded great in thé store but when i conected them at home to my Amp/reciever they showed a lack off bass , it's there but just not thé way i heard it in thé store .. so at first i thought that they were flawd ... But when i conected them to my friend's Onkyo Amp they sounded like they should ... This way i discoverd it was about thé cross-over settings... Only on my NAD Amp i have no idea how to set those settings ... My manual isn't of any help ... There is a bass and trebble knob but those don't have any effect ... So here is my cry for help ...

That model number is a power amp not an integrated.
There may a tone defeat button on your integrated amp.
If you boost the bass too much you can damage the speakers.

I don't need my room shaking ... But there is almost no bass comming from my speakers .. and there should be some lows in place .. which there are none

Your speakers have bi-wire speaker terminals. If the jumper plate that connects the upper and lower terminals is missing and you have connected your speaker wire to the upper pair then the woofer isn't connected at all.
If the plate is missing then you can replace it with some speaker wire. Some people feel that sounds better anyway.
