Wilson Sasha DAW vs. Sabrina X

The DAWs are reputed to be more coherent and revealing as a tribute to dear old dad. I bought a pair recently and love them, but could use another 1/2 octave on the bottom. Subs would be awfully nice. 

Is he running the subs under the mains or using the Lokes internal highpass? If he is highpassing at or above 60hz I would pass and save the money. 
 

the Sasha are a lot more dynamic but once highpassed the dynamics of the Sabrina should be greatly increased. Larger speakers are almost always better but subs used correctly make such a difference it might not matter. 
 

the Sabrina’s measurements show cone break up in the mids, or a least a very strong peak at 3k off axis. Oddly people don’t seem to complain about it though. 

Wilson is a quality speaker manufacturer and has a house sound. I expect there to be a difference - I can’t say if it would be worth the money. And I’d be willing to listen and find out.
