I wouldn't combine the NV115 with a CN or HD cab. Totally different flavours! The NV is sealed. Tight low end, lots of sub bass roll off. More like the tone of the classic 8x10 sealed cabs, but smaller.
The CN cabs are again punchy, but will have a bigger sounding low end, and a bump in the mids that really allows the bass to be heard.
The HD cabs are more classically voiced. Eg, probably the fullest lows, smoother mids.
If you are going down the Berg route I'd recommend the CN212 or 2 x CN112s.
