Bag End S15-D Vs NY151 / Mini CMD151P

For these compact enclosures, tweeters aside, how do they compare in volume handling and low B reproduction ?

I see the LMII + S15-D is a popular rig in the Bag End threads here, I wonder if anyone compared those to the LMII + NY151 or Mini CMD151P combo ?

 

For me here in AUs, the MB is a whole lot more $'s than getting Bag End shipped.

 

Anyone, I'm going to pull the trigger on one of these real soon.
