unbalanced kasi 2 wires lang yun, balance di ba 3?
may effect yung pagreverse ng polarity kung nag add ka ng 2 signals (e.g. mic + woofer) kailangan reverse polarity yung isa dun kasi mag cacancel out yung bass mo. ninipis yung tunog nun imbis na ma reinforce nya. no need to reverse the polarity kung speaker lang gagamitin mo though be conscious yun sa ibang mics na malapit sa bass
try to export your recordings to mono, listen if the bass sounds weaker on mono than on your stereo mixdown, if that's the case then you need to reverse the polarity of your speaker cum mic. or simply move it farther or closer to the bass. imho just use mics, its simpler hehehe
havent tried sa balanced, baka magwork din yun kung gagamitan mo ng DI
