Here's a review of 3 traditional subs and 3 modern (compact) subs by the renown Brent Butterworth in S&V Nov 2009.
However, I could not find this article on S&V web anymore. Is there a possibility that it was being pulled out of S&V website? My guess is that one of the heavy advertisers might have give an earful or whatever to S&V. If that's true, then it is sad (but, it's a reality of life) that S&V is going down the What Hi-Fi crap road.
