“It’s time for some serious bass” says Steve Withers in his recent AVForums review of the awesome SVS PB4000 sub. Awarding 9/10 and a Highly Commended badge he says “the PB-4000 is beautifully engineered…and…a bit of a bargain when you consider its build quality, features and performance. “It can deliver big bass moments with a visceral sense of scale but it never feels forced, retaining an organic cohesiveness that’s a joy.”
