I will have to disagree this time with my good friend Bigtee. The 2W is not an HT sub (that's the V2W) and it has an low-intermediate Q, which IMO is pretty damn good and can't be beat at the price.
Vandersteen 2WQ vs 2W
Is it worth paying extra for the 2WQ? I am limited on funds so I am considering the 2W since they seem to be going for around $500 used. I am leaning toward the 2W, but would pay more if the 2WQ has substantial changes from the 2W. Any opinions on the adjustable "Q" feature would be helpful.
