QTS is the subwoofers response time. Its the actual measure of the drivers free air resonance. Your qts is .561 but they recomend those subs for both sealed or ported. =D
If i can remember correct, my qts on my 15s are like .31
I have heard that the SQ is as good an alpine R if it is in a sealed box. I am getting 4 of these 12"s and 2 amps I was thinking about porting 2 and sealing 2 for my lows and everythig else. How do you all think that would sound?
