P.Audio GST15-500

The P.Audio GST15-500 is a 15 inch (381mm) diameter high performance low frequency woofer. The design utilizes a medium format 3 inch (76mm) nominal voice coil diameter with a very light weight aluminum coil configured in an inside/outside wind geometry. This light weight design, coupled with a low moving mass cone offers excellent transient response. The large format ferrite based magnet structure produces very high conversion efficiency. Inside/outside winding geometry assists in coil cooling and improves both transducer power handling and system reliability. The GST15-500 also features a very long air gap height that improves transducer linearity.

The GST15-500 offers very smooth and controlled amplitude response to 1500Hz and has a useable high frequency limit of 2000Hz. The rated low frequency limit of 40Hz will insure excellent low frequency extension and bass response. The GST15-500 is an excellent choice for high output two way system designs where extended low frequency energy is specified. It is ideally coupled with P.Audio BM-D series and SD series compression drivers. P.Audio offers a wide range of high frequency horns that can provide short throw or medium throw designs when coupled with the GST15-500.

The design features very large diameter impregnated spiders to insure long term linearity. The impregnated spiders and very high system power handling will insure excellent long term performance. The cone is waterproof to improve reliability in high humidity environments.

The GST15-500 features an aluminum die cast chassis that includes P.Audio's Auto Balanced Cooling design that minimizes coil and magnet structure heating, and further improves system performance.
