The Mordaunt-Short Avant architect AC161 fits neatly into any ceiling void allowing it to be installed almost anywhere in the listening environment. The AC161 incorporates an infinitely adjustable tweeter to meet demanding dispersion requirements created by the disparity in ceiling height/floor ratios to produce an incredibly consistent performance. This means treble energy is directed exactly where it is needed. It also means the AC161 can be located in various places whilst still delivering the ultimate high frequency performance.
