The result is more energy in the gap, higher sensitivity, lower distortion and better overall performance. The 15DS115 features a 40mm long, 4.5 inch diameter (116mm) Copper Clad Aluminum Wire voice coil. With a 1600watt AES power rating, 96 dB sensitivity, and over 14 mm of Xvar, this high energy subwoofer is a significant step forward from similar models in the B&C range.", 15DS115, 697478495225, ALT15DS1154M"HIGHLIGHTS 3200 W continuous program power capacity | 116 mm (4.5 in) four layer aluminum voice coil | 35 - 1000 Hz response | 96 dB sensitivity | 60 mm peak-to-peak excursion before damage | Neodymium magnet allows a very high force factor and linear excursion | Double silicone spider with optimized compliance | Ventilated voice coil gap for reduced power compression | Aluminium demodulating ring for very low distortion | ""SPECIFICATIONS Nominal Diameter : 380 mm (15.0 in) | Nominal Impedance : 4 Ω | Minimum Impedance : 4.8 Ω | Nominal Power Handling1 : 1600 W | Continuous power handling2 : 3200 W | Sensitivity (1W/1m)3 : 96.0 dB | Frequency Range : 35 - 1000 Hz | Voice Coil Diameter : 116 mm (4.5 in) | Winding Material : Aluminium | Former Material : Glass Fibre | Winding Depth : 40.0 mm (1.57 in) | Magnetic Gap Depth : 14.0 mm (0.55 in) | Flux Density : 0.8 T | ""DESIGN : | Surround Shape : Triple Roll | Cone Shape : Radial | Magnet Material : Neodymium Inside Slug | Spider : Double Silicone | Pole Design : T-Pole | Woofer Cone Treatment : TWP Waterproof Both Sides | Recommended Enclosure : 80.0 dm3 (2.83 ft3) | Recommended Tuning : 40 Hz | ""MOUNTING AND SHIPPING INFO || Overall Diameter : 393 mm (15.47 in) | Bolt Circle Diameter : 375 mm (14.76 in) | Baffle Cutout Diameter : 354.0 mm (13.94 in) | Depth : 199 mm (7.83 in) | Flange and Gasket Thickness : 15 mm (0.59 in) | Air Volume Occupied by Driver : 7.0 dm3 (0.25 ft3) | Net Weight : 11.6 kg (25.57 lb) | Shipping Units : 1 | Shipping Weight : 12.9 kg (28.44 lb) | Shipping Box : 425x425x224 mm (16.73x16.73x8.82 in) | ""MOUNTING AND SHIPPING INFO || Overall Diameter : 393 mm (15.47 in) | Bolt Circle Diameter : 375 mm (14.76 in) | Baffle Cutout Diameter : 354.0 mm (13.94 in) | Depth : 199 mm (7.83 in) | Flange and Gasket Thickness : 15 mm (0.59 in) | Air Volume Occupied by Driver : 7.0 dm3 (0.25 ft3) | Net Weight : 11.6 kg (25.57 lb) | Shipping Units : 1 | Shipping Weight : 12.9 kg (28.44 lb) | Shipping Box : 425x425x224 mm (16.73x16.73x8.82 in) | "
