Buying Guide

Match impedance and size

Choose a replacement driver or subwoofer with the same ohm rating and physical diameter to avoid amplifier mismatch or mounting issues

Check diaphragm and magnet type

Phenolic, aluminum, and neodymium components affect tonal character and durability; select based on desired sound and heat tolerance

Consider horn flare and exit size

Horn geometry and exit diameter influence dispersion and sensitivity—1" exits suit focused high-frequency projection, larger exits broaden coverage

Confirm accessory compatibility

Protective grilles, service packs, and replacement diaphragms must match model-specific mounting patterns and connector types

Prioritize power handling and application

Match RMS or nominal power handling to your amplifier and intended use—car, pro PA, or studio monitoring—to prevent damage and distortion
