No home cinema is complete without a good center speaker, because this is where most of the acoustic action takes place. The Signature Center 73 naturally features an identical chassis and perfect tonal coordination to ensure a homogeneous all-round sound. The Hi-Res dual tweeter module in the center speaker is flanked by two 170 mm bass-midrange drivers, making it a true 3-way system. Like all of the speakers in the Signature 700 series, the Center 73 also features a bass reflex port in an Airflex configuration to prevent flow noise.
