One look at the back of a subwoofer amplifier and your first thought might very well be “Yikes! What did I sign up for?” But relax – while each knob, gizmo and switch does have its own job, it’s easy to understand what they do once you hear an expert explain it to you. Listen as Andrew Welker, Axiom Design Engineer, explains the Axiom subwoofer amplifier settings.

It’s impossible to understand what the choice before us is without understanding the different classes of amplifiers. We turn to our guru, Alan Lofft, who explains in an article elsewhere on this site entitled Ten Things You Always Wanted to Know About Amplifiers : Log in
