Is my 30hz ported box robbing me?

[Tehgregzor]

My box is tuned to 30hz...i listen to all Alternative/Rock/Metal, no rap ever plays through my system...so am i robbing myself of output because of the low tuning of my box?

Equipment list in Sig.

BTW..this is my first real install, did it with leftover scholarship money, therefore no real cash for me to upgrade anything just yet.

i think 40 hz would work better for you.

36hz, 29 inches port area 2ft for 600 watts 2.25 with 31 inches pa if you have less power
