Wilson’s Alexx V vs Alexandria XLF

@carey1110 

my experience with Wilson Sabrina that can most likely be applied in your case

1. the farther away they are from the front wall the better the bass quality - these rear ported speakers need room to breathe

2. placement and toe in - I’d start with setting speakers 8’ apart measured from center to center of tweeter. Toe in to shoulders or even direct to ears. 
 

The Sabrinas sound much bigger than their physical size. I would expect the Alexx V to be similar in this regard. Will the bigger speakers fill the space better? Yes. But are you sure you have reached the full potential with your current setup? 

Also…if you are missing fullness and bass at lower volumes with the Alexx V to me that includes your current amplifiers may not be the right match. Wilsons go down to 2ohm and that can cause phase shifts with amps that aren’t stable or don’t have enough juice at 2ohms. You will most likely face the exact same issue at lower volumes with bigger speakers.
