Buying Guide

Match driver size and throat

Confirm the compression driver throat diameter and horn throat match your existing horn or enclosure to ensure proper acoustic coupling and avoid installation issues

Check magnet material

Neodymium magnets offer high flux in compact packages for lighter compression drivers, while ferrite magnets are heavier but often lower cost for subwoofer drivers

Confirm impedance and power handling

Choose drivers and subwoofers with impedance (ohms) and RMS power ratings compatible with your amp and crossover to prevent thermal or electrical mismatch

Consider diaphragm and horn materials

Phenolic or aluminum diaphragms and aluminum horns affect timbre, durability and dispersion; pick materials that suit stage or FOH use and expected SPL

Factor mounting and basket dimensions

Verify bolt circle, cutout diameter and basket depth for subwoofer replacements to ensure the driver fits into your existing cabinet without modifications
