ported enclosures tend to sound less "tight" than sealed. toss the SA in a sealed enclosure and the W6 in a ported enclosure and then make your comparison...i vote w6 just to **** everyone off lol i love it but i own both currently and love the sound of my w6' in a sealed box but the sa's i use ported abd they dont sound bad at all just not as "tight" as the jl
