18″ (460 mm) nominal diameter — large woofer for powerful low-frequency output suitable for PA sound reinforcement.
Heavy-duty paper or composite cone — rugged construction to handle high power levels.
Large voice coil (often 3″–4″) — better heat dissipation and higher thermal power handling.
Ferrite or ceramic magnet — common in professional drivers for strong magnetic fields.
Cast aluminum or robust frame for stability and reduced resonance.
High power handling, often from ~800 W RMS up to 1200 W or more, depending on the design.
Wide frequency range to cover deep bass and low midrange when paired correctly with a crossover and tweeter/horn.
Sensitivity typically ~96–98 dB or higher — efficient output with strong sound pressure.
Ideal for live sound reinforcement, concerts, DJ systems, halls, auditoriums and portable PA setups.
Often used in multi-way passive cabinets where the 18″ driver handles low/mid lows while a horn or compression driver handles high frequencies.
A speaker with a designation like PZ 18-H 83-C would be an 18-inch professional PA (public address) speaker driver or component, usually used as the low-frequency woofer / bass section in larger PA speaker systems. These are commonly used in pro audio setups — such as concert sound systems, DJ rigs, stage speakers, halls, and live public address systems.
