DON’T GET BOOM-BOOZLED
Subwoofers – Watts the Word?
Most common amp spec used for marketing
Maximum power measurement, regardless of how short the duration. A single click, almost always measured at 1kHz. Utterly meaningless in subwoofer applications.
Usually 50% of PEAK
A vague rating indicating the maximum dynamic power, usually specified using very little bass content.
Repeating Burst RMS
A 25% duty cycle measurement. Below 125Hz, these amplifiers can only deliver as little as 1/4 their rated power. Output power at frequencies below 125Hz should be de-rated by up to 75%.
ALL BASSBOSS SUB AMPS
BASSBOSS subwoofer amps deliver 100% of their rated output continuously, as a sine wave, at sub-bass frequency range. There is no reduction in power at deep bass frequencies. Amplifiers rated this way can deliver up to 8X more power at low frequencies than amplifiers rated to have the same “number of watts”, specified by another method.
