Like its big brother, it keeps the dual tweeter design and selectable bipole/dipole configurations. It’s a little smaller so it will fit in more places the FXi A6 does not, but still fully matched to the RTiA series speakers.SURROUND LOUDSPEAKERQty Included PairOrientation HorizontalHeight12″ (30.48 cm)Width11.375″ (28.89 cm)Depth7.437″ (18.89 cm)Weight9 lbs (4.08 kg)Driver Enclosure Type Acoustically Tuned VentDriver Complement• (1)  5.25″ (13.34 cm) d (Round) Dynamic Balance driver with polymer composite cone and rubber surround – Mid/Woofer• (2)  1″ (2.54 cm) d (Round) Dynamic Balance silk polymer composite dome – TweeterMounting Type Keyhole HangerAvailable Orientations HorizontalTotal Frequency Response50 Hz → 27,000 HzNominal Impedance8 ohmsNominal Impedance60 Hz → 26,000 HzAudio Inputs-Speaker Inputs(1) Pair of 5-way Binding Posts – Gold PlatedRecommended Amplifier Power Per Channel20 watts → 150 watts
