About the D130

The JBL D130 is a 15-inch (38 cm) cone type wide-range speaker unit first introduced in 1948 and designed by James B. Lansing. It features a lightweight, shallow paper cone with an aluminum center dome that extends the mid and high frequency response. The voice coil is a 4-inch flat wire aluminum ribbon coil, edgewise wound with a diameter of 10.2 cm, immersed in a strong Alnico V magnet magnetic circuit weighing 5.4 kg. The frame is made of aluminum die-cast. It was widely used in home hi-fi systems from the 1950s through the 1960s, in early Fender amplifiers, and in commercial sound reinforcement. The D130 is known for its outstanding sensitivity, range, and dynamic response, with a sound pressure level of 103 dB at 1 kHz and a recommended enclosure volume of 114 to 338 liters. It handles approximately 50-60 watts RMS power and has an impedance of 8 or 16 ohms depending on the version. The speaker depth is about 143 mm, and it weighs approximately 8.6 kg (19 lbs). The D130 remains highly regarded for its tonal qualities and historical significance in audio and musical instrument amplification.
