The Mordaunt-Short Avant architect AC261 features a switchable Mid/HF level which gives the listener ultimate EQ adjustment. Like all Avant Architect in-ceilings, it fits neatly into any ceiling void. The AC261 incorporates an infinitely adjustable tweeter to meet demanding dispersion requirements created by the disparity in ceiling height/floor ratios for the ultimate in consistent performance. This means treble energy is directed exactly where it is needed. It also means these in-ceiling units can be located in various areas of the room to maximise convenience.
