: This measures continuous power handling. Aim for a woofer that matches your amplifier's output, ideally with about 20% more amplifier power than the woofer’s RMS for "headroom".
: Expressed in decibels (dB), higher sensitivity means the woofer converts power into sound more efficiently, often resulting in clearer bass. buy woofer online
: Usually 2, 4, or 8 ohms . Your woofer's impedance must be compatible with your amplifier to avoid damaging your equipment. : This measures continuous power handling
