Exceptional control of proximity effect vastly increases working distance without on-axis coloration
Accurate frequency response due to controlled proximity effect which allows for neutral mid-and-high frequency reproduction
Off-axis attenuation is flat and broad resulting in superior quality of rejection of unwanted sound sources for increased vocal clarity
Shock Mount design for exceptional rejection of handling noise without any loss of low frequency response
Dent-resistant, hardened carbon-steel grille design lined with hydrophobic woven fabric provides exceptional plosive and wind protection, while offering virtually waterproof protection
