The PD 1890 is an 18-inch raw bass driver built for serious low-frequency work in professionally built subwoofer cabinets. Its cast aluminium chassis provides the rigidity needed to keep the moving assembly aligned under stress, and the double suspension design helps the cone return true after hard excursions. With an AES power rating of 800 watts and peaks up to 3200 watts, this driver is intended for scoop bins, bass reflex cabinets and horn-loaded subwoofers used in churches, clubs and concert systems. Sensitivity of 98 dB (1W/1m) means it converts amplifier power into audible output efficiently, an important factor when running long events on limited amp channels. Power compression of just 1.6 dB at rated power helps the system hold its tonal balance as levels climb. For Nairobi's sound rental firms and church technical teams, the PD 1890 is a proven choice for cabinets that must deliver deep, controlled bass night after night. Fit it into a recommended enclosure volume of roughly 90 to 220 litres and pair it with suitable amplification.
