The BestCarAudio.com team received a great question about subwoofer polarity and how a crossover affected the phase at the crossover point. Specifically, the question focused on whether the subwoofer polarity needed to be reversed if the sub amp used a -12 dB/octave filter. The short answer is yes. As always happens with audio systems, the full answer isn’t as simple once we Read more
Understanding how DC voltages combine is quite simple. They add linearly when we wire sources (like batteries) in series. But understanding how AC waveforms combine is complicated. AC waveforms don’t always sum intuitively unless the peaks and valleys align perfectly. We see many examples where people interchange the terms phase and polarity. In reality, those words refer to Read more
When it comes to high-end car audio systems, you may hear your system designer or installation technician talk about phase. A discussion of phase is a pretty high-level concept and not something that most consumers concern themselves with. However, it’s an important topic and getting it right requires proper system design and calibration to ensure that your music sounds its Read more
