Buying Guide

Match driver type to application

Choose compression drivers and horns for horn-loaded PA or car-audio mid/high duties, and cone woofers for low-frequency subwoofer replacement

Check diaphragm and material

Phenolic and aluminum diaphragms affect tonal character and durability—phenolic often adds warmth while aluminum can increase transient detail

Consider magnet and motor strength

Neodymium magnets offer strong flux in compact drivers, whereas larger ferrite motors can be heavier but cost-effective for certain woofers

Match impedance and power handling

Confirm 8-ohm or other impedance compatibility with your amplifier and choose a driver with power handling that safely matches your system's output

Horn geometry affects dispersion

Exponential and other horn profiles change coverage and loading—pick a horn type that suits the venue size and listening position for better dispersion
