Buying Guidance

Match cone diameter, voice coil impedance, and power handling to your cabinet's designed volume and crossover point — an oversized woofer in an undersized enclosure underperforms regardless of its individual spec sheet.

Maintenance

Inspect the surround and spider for cracking or stiffening with age, particularly in cabinets stored in high-humidity or high-UV-exposure conditions — these are the most common woofer failure points, not the magnet or voice coil.
