How much can bad speaker positioning affect to bass performance? I bought pair of cerwin-vega 12" speakers, and they are lacking bass, until I give it +6 boost, and even then they sound poor. It lacks the punch, that you feel in your chest and rumble in your gut. They sounds just like basic multimedia speakers. I have double checked everything (polarity, settings, sufficient RMS). May the bad room shape eliminate all the power of the bass this bad? Should I try the outdoor?
