I've been using an earlier but not quite vintage model with my garage system. In the nearfield position, these are absolutely incredible but quickly lose their punch when used from a distance.
A little tweak I discovered is to shorten the captive power cord. The unit now gets up to operating temp quicker and an added bonus is the sound of the metal expanding has a purer tone.
My next tweak is to dim the lighted rocker switches for those quiet nights when they can be a distraction.
