P AUDIO GST 18 1500

P AUDIO GST 18 1500

The P Audio GST18-1500 is an 18 inch (457mm) diameter high performance very low frequency sub woofer transducer. The design utilizes a very large format 5 inch (127mm) nominal voice coil diameter with a very high power copper based coil configured in an inside/outside wind geometry. The large radiating area and deep bass performance insure that the GST18-1500 is capable of very high impact low frequency response. The transducer also offers a double silicone spider design that improves long term mechanical reliability and mechanical linearity. The large format ferrite based magnet structure produces very high conversion efficiency. The ferrite design includes a double stack permanent magnet geometry that increases maximum physical excursion capability. Inside/outside winding geometry assists in coil cooling and improves both transducer power handling and system reliability. The GST18-1500 also features a very long air gap height that improves transducer linearity.
