Wilson Audio Sasha DAW’s or Alex 1’s?

Sorry, Alexia 1’s, not Alex. (Not my fault that Wilson uses variations of the same Russian name for all of their speakers!  :) 

So, to make the question more clear, they both are on the used market, so auditioning in my home isn’t an option. 
Used, for very similar money, you can get the newer Sasha DAW or the older Alexia 1’s, a larger, higher end speaker, but older tech. 
Not sure what speaker is a better speaker. My room is 16’ x 38’ with 8’ ceilings. (Basement man cave type thing.) 

Alexia 1’s are fantastic. They can fill a space, but can also work in a smaller environment. There is a certain member here that will tell you they have an “evil” load and only a couple of amps can run them. Which isn’t true. They do pose a challenging load, but not beyond what their own specs state. They are fairly sensitive 4 ohm/@90db. I have no experience with the Sasha’s, though there are similarities. I think sonically there would be a similar sound, but the Sasha’s don’t have the time delay adjustment that the Alexia’s have. That aspect is probably one of the key differences that need to be considered, and might make placement a little more critical with the Alexia v the Sasha. All Wilson’s are highly sensitive to positioning. Makes all the difference in the world. A friend has Alexandria XLF’s and it is shocking how much difference an inch or two in any direction can make with those speakers.

@jtasker the manual goes through the WASP process well. It is worth it to start there and then see how that works in your situation/environment. Then tweak as required from there. Room treatment makes all the difference as well and should be considered in the process.
