Your question was about placement of your sub. If a sub is placed near a wall away from corners it has two surfaces to work with boosting the subs efficiency by 2 decibels, if you corner load ( placement ) your sub you get a 3 decibel increase in efficiency. If calibrate your system with an sound pressure level meter you won't hear the difference but you sub won't have to work as hard, if you sub had an efficiency of 98 decibels @ 1 watt @ 1 meter to increase the sound output of your sub 3 decibels you would have to double the power to the sub, 3 decibels more 4 watts and so on. The breakdown of these numbers are as follows in watts ( 1 - 2 - 4 - 8 - 16 - 32 - 64 - 128 - 256 - 512 - 1024 ) A note on human hearing our ability to hear a change in volume is 3 decibels, so when you push the volume up you must double the wattage to actually notice a difference in volume. hope this helps corners are the best location for you sub it's like doubling the power of your sub for free.

Umm, the human is quite capable of discerning volume changes much smaller than 3 dB! Yes, you need to double the wattage to get an increase in volume of 3 dB, but that's not the point.

See my other post for why the corner is about the worst place you could put a half-decent sub.

Anyone elses glass break detector go off when the sub gets rolling?
