This is fourth order for an fi bl 10. About .502 cu ft sealed and 1.05 net cu ft ported tuned to 45 hz. Its going where the center console is in a chevy silverado. The picture displays the port on the bottom but it will actually be firing upward.

Well without dimensions it hard to tell exactly, but your port looks to be significantly undersized.

How much power are you going to be running this on? Why not just use a ported box?

i get that the sketch is a top view and its missing the lid... but i can't seem to find the port?. anyways i dont think you need 45's on the sealed section it will give you a little bit more of volume.

Would he need the high qts for a fourth i have been wondering that myself whyn i was looking at the qs

x2 on this.... what do you think Triticum Agricolam? would the sub be better suited if it was built with the option of high qts or regular?

Yeah the high QTS option would be better for 4th order bandpass box use. In a 4th order bandpass enclosure low QTS subs are much more peaky/have smaller bandwidth than a higher QTS sub would, all else being equal.

OP BL or Q?? The BL series don't have a high QTS option.
